LED Display Hart Differential DP Pressure Transmitter

Differential Pressure / DP High Performance Transmitter

1. Overview

Differential pressure transmitters measure the difference between two pressures.

This equipment will sense the difference in pressure, between two ports and produce an output signal, with reference to a calibrated pressure range.

The industrial differential pressure transmitters are made of two housings.

The pressure sensing element is housed in the bottom half, and the electronics are housed at the top half.

It will have two pressure ports marked as “High” and “Low”.

It is not compulsory that the high port will be always at high pressure and the low port always at low pressure.

3. Technical Parameters
