Understanding Pressure Transmitters: A Beginner’s Guide
In the industrial world, pressure transmitters play an important role in providing smooth operations across applications such as oil and gas, aerospace, and automotive. These devices are important for accurate pressure readings to ensure the optimal performance in operations.
In this guide, we uncover the key elements of a pressure transmitter including the data extracted, sensor technology, and housing material.
What is a Pressure Transmitter?
A pressure transmitter is a device that measures the pressure of fluid or gas by translating the low-level output of a sensor to a higher-level signal which is suitable for transmission to a site where it can be processed further.
What Information Can Pressure Transmitters Provide?
With pressure transmitters, users can measure pressure efficiently and reliably in real-time. Pressure readings offer users different types of information such as output signals, pressure ranges, and accuracy.
Output Signal
Typically, pressure transmitters produce a voltage or mA signal output. The 4-20 mA output is the most common output signal.
Pressure Range
Pressure transmitters operate within certain pressure ranges. Depending on the application, the pressure range can vary.
Accuracy
Static accuracy is the most common type of accuracy provided from pressure transmitters which include non-linearity, hysteresis, and repeatability which are measured under static conditions at ambient temperatures. Additionally, the total error band (TEB) reflects the effects of temperature variations and other conditions on pressure transmitters’ overall accuracy.
Pressure Transmitter Piezoresistive Sensor Technology
Commonly, PMC-STS pressure transmitters are made up of piezoresistive technology through semiconductor strain gauges. With these strain gauges, electrical resistance is altered through mechanical deformation to ensure accurate pressure readings.
What are Pressure Transmitters Made of?
To provide durability, pressure transmitters are built with various types of materials that are best suited for challenging applications including:
- Stainless Steel
- Titanium
- Hastelloy
- Inconel
- PVDF (Kynar)
· FFor example, the ATM.1ST Pressure Transmitter is constructed of 316L stainless steel material. The modular construction offers manufacturing flexibility that can provide long-lasting durability in the long run. Alternative materials include titanium and Hastelloy.
