Differential Pressure Transmitter With ATEX

China differential pressure transmitter with ATEX

4~20mA micro pressure sensor differential pressure sensor is a measure of the difference between the two ends of the transmitter ,output standard signal (eg 4 ~ 20mA, 1-5V) differential pressure transmitter and pressure transmitter with the general difference is that there are two pressure ports,  the differential pressure transmitter is generally divided into positive and negative terminal end, under normal circumstances, Positive pressure side pressure should be greater than the negative pressure section.

Applications:

1.Widely used for measuring differential pressure (or pressure), level, density of liquid, gas or steam and convert the value of above into current signal output or digital protocol output.

2.The pressures are directly applied to the isolating diaphragm that provide isolation and resistance against process fluid corrosion.

3.Being microprocessor based, the electronic circuit is extremely versatile and accurate.

4.Combined with the sensor precision, it provides the high accuracy and range ability.

5.Transmitter performance is improved by continuous monitoring of the sensor temperature and corresponding corrections.

6.A local display permits easy reading and writing of data.
