Pressure Transmitter (4~20mA, G1/2)

Product Code: APB3H / APB3HV

4~20mA Current Loop Output (pressure and vacuum options)

The APB range of 4~20mA high accuracy, low cost ceramic pressure transmitters are designed for use in most industrial applications and are suitable for the measurement of most pressure mediums.

The transmitters incorporate a high quality thick-film ceramic sensor and special amplified circuit. Output is configured to 4~20mA current loop. The pressure diaphragm is made from ceramic material and its wetted parts are made from 316L stainless steel.

Because of the thermal stability of ceramic and its thick-film resistance, the transmitter can be operated at a higher temperature range; at the same time, this also makes the zero and sensitivity thermal shifts over the whole operating temperature range of the transmitter very small.
