Introduction
Pressure transmitters are essential instruments used in industrial plants to measure and monitor fluid pressure.
They convert pressure signals into electrical signals that can be transmitted to control systems such as PLC or DCS.
What Is a Pressure Transmitter?
A pressure transmitter is a device that measures pressure and converts it into a standardized output signal.
The most common output signal is 4–20 mA, which allows the measurement to be transmitted to monitoring and control systems.
How Pressure Transmitters Work
Pressure transmitters detect pressure using sensing elements such as diaphragms or strain gauges.
The detected pressure is converted into an electrical signal and transmitted to control systems.
Applications
Pressure transmitters are widely used in:
Steam systems
Water pipelines
Gas systems
Chemical process equipment
Conclusion
Pressure transmitters provide accurate pressure measurements that are essential for monitoring and controlling industrial processes.
