In general, the pressure transmitter often refers to the pressure transmitter and the differential pressure transmitter, which are mainly composed of the sensor of the pressure measuring element, the measuring circuit and the process connection. which can convert the received pressure signals such as gas and liquid into standard current and voltage signals (4~20 mADC) to supply secondary instruments such as indicator alarm, recorder, regulator for measurement, indication and process regulation.
The pressure transmitter can be divided into general pressure transmitter (-100 Pa~120 MPa) and differential pressure transmitter (0.1~1.5 kPa) according to the range of pressure measurement.
3151 Intelligent Pressure/Difference Transmitter / Main Role
The principle of transmitting pressure signals to electronic devices and then displaying pressure on a computer is:
When a mechanical signal of pressure such as water pressure is converted into an electronic signal such as a voltage or current (usually 0-5 V or 4-20 mA), the pressure and voltage or current are linearly proportional.
