Power source for pressure transmitter
Thread Content
I have a question: the power supply for the pressure transmitter is 24VD, and the pressure value is 0.14 MPa. What type of unit does this 0.14 MPa represent?
The air supply for the pneumatic pressure transmitter is 0.14 MPa, and the transmitted signal ranges from 0.02 MPa to 0.1 MPa. It might be impossible to find pneumatic pressure transmitters now.
Pressure transmitters come in pneumatic and electric types; the air supply pressure for pneumatic ones is 0.14 MPa, while electric ones are powered by 24 VDC.

Such instruments are generally powered by DCS cards or the loop-powered terminals of data acquisition systems. The gauge that the original poster is talking about is an old device from decades ago. Pneumatic pressure sources are divided into two categories: one is the conventional air pressure source with a pressure of 0.14 MPa, and the other is a pressure-amplified source with a pressure of 0.28 – 0.3 MPa. Some manufacturers that produce pneumatic components or actuators still likely have such products available; they are intrinsically safe devices that require no certification, are very precise and safe, but of course they are also expensive.
