I had an emergency, a branch took out my wire and hub and grounds. It was scary. Jason was very fast and responsive. He looked at the job and quoted a price, but then when investigating the job more in detail, he realized it was a more complex project. He worked with the permit dept, pge and kept me informed though out the process. It all went smoothly and he even followed up the next day to check up with me to make sure all was fine. He's local here in Felton and a wonderful human. Cherie

Pressure Transmitter Service in Felton, CA

A pressure transmitter is a robust industrial instrument that measures the pressure of a gas or liquid in a pipe or a vessel and converts that measurement into a standard electrical signal. This signal, most commonly a 4 to 20mA current, is then sent to a control system like a PLC. This allows for the continuous, real time monitoring and control of the process pressure. Accurate pressure measurement is often critical for ensuring the safety of a pressurized vessel, the quality of a product, or the efficiency of a process. Our instrumentation services ensure these vital instruments are installed and maintained correctly.

There are several different types of pressure measurements that can be made. The most common is gauge pressure, which measures the pressure relative to the local atmospheric pressure. This is what you measure with a standard tire gauge. Absolute pressure measures the pressure relative to a perfect vacuum. Differential pressure (DP) transmitters are a versatile type of instrument that measures the difference in pressure between two separate points. DP transmitters can be used to measure the pressure drop across a filter, the flow rate of a fluid, or the liquid level in a pressurized tank.

Our services include the complete installation of new pressure transmitters. This starts with the proper mechanical installation. The transmitter must be connected to the process pipe or vessel correctly, often using a block and bleed valve or a multi valve manifold that allows the instrument to be safely isolated from the process for maintenance or calibration. We also install the small diameter impulse piping or tubing that connects the process to the transmitter’s sensor, ensuring it is leak free and sloped correctly to prevent trapped air or liquid.

The electrical installation of a pressure transmitter is a task that requires precision. We will run a shielded, twisted pair instrumentation cable from the transmitter’s location back to your main control panel. It is critical that this low level signal cable is run in its own dedicated conduit to protect it from the electrical noise generated by high power motor cables. We then connect the two wires of the 4 to 20mA loop to the correct terminals on the transmitter and the PLC’s analog input card. We also ensure the cable’s shield is properly grounded at one end to prevent noise interference.

Calibration is an essential service for ensuring the accuracy of your pressure measurements. Over time, an instrument’s accuracy can drift. Our technicians can perform a two point calibration on your pressure transmitters to verify and adjust their performance. This process involves isolating the transmitter from the process and connecting a high accuracy pressure calibrator. We then apply a known low pressure (the zero point) and a known high pressure (the span point) and adjust the transmitter’s output so that it reads exactly 4 mA and 20 mA at these two points.

If you are experiencing problems with an existing pressure transmitter, such as an erratic reading, a reading that is stuck at zero, or a measurement that you know is incorrect, our skilled technicians can provide expert troubleshooting. We will use a systematic process to determine the root cause of the problem. The issue could be a plugged impulse line, a leak in the tubing, a faulty transmitter, a problem with the 24 volt loop power supply, or an issue with the wiring. We can quickly diagnose and repair the fault to restore your critical measurement.

Our technicians are experienced, professional, and safety certified. We understand how to work safely in an industrial environment and will follow all of your facility’s safety procedures, including lockout/tagout and hot work permitting. We know that accurate and reliable pressure measurement is critical to your operation’s success.

Most Common Pressure Transmitter Service Questions

Pressure is one of the most commonly measured variables in industrial processes. The instruments that measure it are critical for safety and control, but their operation can be a source of questions. The following answers explain some of the key concepts related to industrial pressure transmitters.

The difference between gauge pressure and absolute pressure lies in the reference point that is used for the measurement. It is all about what “zero” pressure is being compared against. Gauge pressure is the most common type of pressure measurement. It measures the pressure of a process relative to the surrounding atmospheric pressure. This means that a gauge pressure reading of zero does not mean there is no pressure; it means the pressure inside the pipe or vessel is the same as the atmospheric pressure outside of it. A standard tire pressure gauge, for example, measures gauge pressure.

Absolute pressure, on the other hand, measures the pressure of a process relative to a perfect vacuum, which is a state of zero absolute pressure. An absolute pressure transmitter has a sealed reference chamber on one side of its sensor that is at a permanent, near perfect vacuum. Therefore, its measurement is not affected by changes in the local atmospheric pressure. This is important for certain scientific applications or for processes that operate under a vacuum, where atmospheric pressure changes could introduce a significant error into a gauge pressure reading.

For most industrial applications that operate at pressures well above atmospheric, a simple gauge pressure transmitter is sufficient and is the most common choice. An absolute pressure transmitter is used in specific applications where the influence of barometric pressure is a concern or where a vacuum is being measured.

A differential pressure (DP) transmitter is one of the most versatile and widely used instruments in all of industrial process control. Instead of measuring a single pressure, a DP transmitter is designed to measure the difference in pressure between two separate points. It has two process connections, a “high side” port and a “low side” port, and its output signal is proportional to the pressure on the high side minus the pressure on the low side. This simple ability to measure a difference opens up a huge range of applications.

One of the most common uses for a DP transmitter is to measure the flow rate of a fluid in a pipe. This is done by installing a device called a primary element, such as an orifice plate or a venturi tube, into the pipe. This element creates a small, predictable restriction. As the fluid flows through this restriction, its velocity increases, and its pressure drops. The DP transmitter is connected with taps on either side of this restriction, and by measuring the pressure drop, it can accurately calculate the fluid’s flow rate.

Another major application for a DP transmitter is to measure the liquid level in a pressurized tank. By connecting the high side port to the bottom of the tank and the low side port to the vapor space at the top of the tank, the transmitter can measure the hydrostatic head pressure of the liquid while automatically compensating for any changes in the tank’s blanket pressure. DP transmitters are also used to measure the pressure drop across a filter to determine when it is clogged and needs to be changed.

The proper installation of a pressure transmitter is crucial for its accuracy and reliability. The installation involves both a mechanical component and an electrical component. The mechanical installation starts with connecting the transmitter to the process pipe or vessel. This is typically done by first installing a “process tap,” which is a small valved connection on the main pipe. Then, a small diameter tube, called an “impulse line,” is run from this tap to the transmitter’s sensor.

It is very important that this impulse line is installed correctly. For a steam or hot liquid application, the line may need to have a special loop or “pigtail” siphon in it to protect the transmitter from high temperatures. For a gas application, the line should be sloped to allow any condensed liquid to drain back into the process. For a liquid application, the line should be sloped to allow any trapped gas bubbles to vent back up to the process. Often, a special valve manifold is installed at the transmitter, which allows it to be safely isolated from the process for calibration or removal.

The electrical installation involves running a shielded, twisted pair cable from the transmitter back to the control panel. This cable carries the 24 volt DC power to the instrument and the 4 to 20mA signal back to the PLC. This cable must be run in a dedicated conduit to protect it from electrical noise. The shield of the cable must be grounded at the panel end only. An experienced technician will ensure all these details are handled correctly.

A three valve manifold is a special valve assembly that is commonly installed directly onto a differential pressure (DP) transmitter. It is a compact block that contains three separate valves: a high pressure block valve, a low pressure block valve, and an equalizing valve. This manifold is an essential accessory that allows for the safe and easy isolation and calibration of the DP transmitter without having to shut down the main process.

The high pressure and low pressure block valves are used to isolate the transmitter from the process. In normal operation, these two valves are open, and the equalizing valve is closed, allowing the transmitter to measure the process pressures. When a technician needs to perform a calibration or remove the transmitter for service, they first close both the high and low pressure block valves. This safely traps the process pressure and isolates the transmitter from the live line.

After the block valves are closed, the technician then slowly opens the middle valve, which is the equalizing valve. This valve connects the high pressure and low pressure sides of the transmitter’s sensor together. With the pressure equalized on both sides, the transmitter’s output should drop to zero (or 4 mA). This is a quick and easy way to check the transmitter’s zero point. The manifold also has a small vent port that allows the technician to safely bleed off any trapped pressure before removing the instrument.

Calibrating a pressure transmitter is the process of verifying and adjusting its output to ensure it is accurate. The most common procedure is a two point calibration, where the technician checks and adjusts the transmitter’s zero and span settings. This requires a high accuracy, certified pressure calibration device that can both generate a precise pressure and measure the transmitter’s milliamp output.

The process begins by isolating the transmitter from the process, usually by closing the block valve on its manifold. The technician then connects the pressure calibrator to the transmitter’s input port. First, they will check the zero point. They will apply a pressure to the transmitter that corresponds to the 0% point of its measurement range. They will then check the transmitter’s output on the calibrator’s screen. If it is not exactly 4.00 mA, they will use a handheld communicator or the adjustment screws on the transmitter to trim the zero until it is perfect.

Next, they will check the span point. The technician will use the calibrator to apply a pressure that corresponds to the 100% point of the measurement range. They will then check the output again. If it is not exactly 20.00 mA, they will make an adjustment to the span setting. It is good practice to repeat this process and to also check a few intermediate points, like the 50% point, to ensure the transmitter is accurate and linear across its entire range.

An incorrect reading from a pressure transmitter can be one of the most frustrating problems to troubleshoot in an industrial plant. The issue can stem from the process, the mechanical installation, or the electrical loop. A very common cause, especially for low pressure measurements, is a plugged impulse line. The small tube that connects the process to the transmitter can easily become clogged with debris or solidified process material, which prevents the true process pressure from reaching the sensor.

Leaks in the impulse lines or at the manifold fittings are another frequent cause of incorrect readings. Even a very small leak can cause the pressure at the sensor to be lower than the actual pressure in the main pipe. For a differential pressure transmitter, an incorrect reading can be caused by the liquid level being different in the high and low pressure impulse lines, which creates an erroneous pressure offset.

From an electrical standpoint, a variety of problems can cause an incorrect reading. A low loop power supply voltage, a ground loop caused by improper shield grounding, or electrical noise being induced on the signal wire can all corrupt the 4 to 20mA signal. The transmitter itself could also be faulty, or it may simply have drifted out of calibration over time. A skilled instrumentation technician will systematically investigate all these potential causes to find the root of the problem.

The “turndown ratio,” also known as rangeability, is a specification that describes the flexibility of a pressure transmitter. It is a measure of the ratio between the maximum pressure that the transmitter can be calibrated for (its Upper Range Limit or URL) and the minimum pressure span that it can be accurately calibrated to. For example, if a transmitter has a URL of 300 PSI and a turndown ratio of 100:1, it means that its calibrated range can be “turned down” to a minimum span of 3 PSI (300 / 100).

This is a very important feature in modern “smart” transmitters. It allows a single transmitter model to be used for a very wide range of different applications in a plant. For instance, the same 300 PSI transmitter could be accurately calibrated for a 0 to 300 PSI application, or it could be re ranged for a 0 to 50 PSI application, or even a 0 to 10 PSI application. This greatly reduces the number of spare transmitters that a plant needs to keep in its inventory.

A higher turndown ratio generally indicates a higher performance and more flexible transmitter. It gives a plant engineer the ability to easily re purpose a transmitter or to fine tune its measurement range for better resolution without having to buy a new instrument. When commissioning a transmitter, the technician will use a handheld communicator to set the desired 0% and 100% range points within the transmitter’s allowable turndown limits.

HART, which stands for Highway Addressable Remote Transducer, is a widely used communication protocol in the industrial automation world. It is a “hybrid” protocol that combines a standard 4 to 20mA analog signal with a simultaneous digital communication signal. This allows a modern “smart” pressure transmitter to send much more information back to the control room than just the simple process pressure reading.

The HART protocol works by superimposing a low level, high frequency digital signal on top of the standard 4 to 20mA analog current. This digital signal does not interfere with the primary analog signal, so the transmitter can be used in a traditional analog control loop. However, by using a special HART handheld communicator or a HART enabled input card in the PLC, a technician or engineer can access this digital information.

This digital channel allows a technician to remotely configure all the transmitter’s settings, such as its range, damping, and engineering units, from the comfort of the control room or from any point along the two wire loop. It also allows the transmitter to send back a wealth of diagnostic information, such as its own health status, the temperature of its sensor, and detailed error codes. This makes troubleshooting much faster and enables a more proactive, predictive maintenance strategy.
