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

Product Code: APB3 / APB3V

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 (0~5V, 0~10V and 1~5V also available). 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.
