Pressure Transmitter

Pressure transmitter is a sensor that provides real-time measurements. To ensure the safety of working environment, many people monitor or control pressure to achieve their desired value. Pump systems, Compressor, industrial process monitoring, laboratory and petroleum as well as other applications all use electronic pressure sensors as reliable devices for their liquid or gas pressure measurement.

    Operating Principle and Applications
    Pressure usually plays an important role in various industrial processes. It is one of the most broadly measured variables in the process industries. The pressure transmitter, also known as hydrostatic device while measuring liquid level, is a sensor that not only can be used to measure fluid pressure, but also liquid level. It converts the physical variable pressure into an electrical output signal, which is then immediately transmitted to a device like digital panel meter, computer, PLC or HMI to ensure the result is delivered in real-time. A common application is open tank liquid level measurement, for example. It means that the tank or container is open to the atmosphere. When employing the pressure transmitter, you can install the device on the side of the bottom of a tank to get an accurate reading. The pressure sensor will detect the actual level of fluid in the tank and give the resulting liquid level. Please note that if the tank is closed (pressurized), a gauge pressure transmitter will not work because the sensor will measure both the pressure exerted by the liquid and the vapor pressure above the liquid.
    To briefly introduce the principle of the pressure transmitter, here we give an example of a common pressure sensor which has a pressure sensitive diaphragm with strain gauges bonded onto it. This kind of pressure transmitter uses the strain gauge to measure the force acting on them. When the strain gauge is deformed by the applied force, this deformation of the strain gauge causes a change in resistance. Then, through the designed circuit, the change of resistance is converted to voltage or current variations resulting in a corresponding output. Once the applied pressure releases, the strain gauge returns to its original state.
    It is important to select a pressure transducer that is suitable for the application. By mounting it, you can measure and monitor the pressure or liquid level to maintain an optimal value.
