Pressure Transmitter with LED Indicator Display (4~20mA, G1/4)

Product Code: APD / APDV

4~20mA Current Loop Output, 4-Digit LED Display (pressure and vacuum options)

The APD 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 have an integral bright red LED display with 4-digits each 9mm (0.36") high.

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.

* for the range -1...+0 bar a silicon pressure element will be supplied
