The high-accuracy air pressure transmitters is an optimal solution for applications requiring high precision and reliability. The differential pressure transmitters of the  series are used to measure differential pressure, overpressure and vacuum. They provide one adjustable pressure range and one output signal.

A differential pressure transmitter is an instrument that can consistently and accurately create a pressure drop in a pipe and then use the pressure measurement on either side to provide the rate of flow within the pipe. A differential pressure flow transmitter can be easily installed in many applications.

How does a differential pressure sensor sense pressure? 

Typically, the two pressures to be measured are applied to opposite sides of a single diaphragm. The deflection of the diaphragm, either positive or negative with respect to the resting state, determines the difference in pressure.

Differential Pressure, also known as DP, measures the difference in pressure between the clean (clean air plenum) and dirty (filter side or dirty air plenum) sides of your dust collector. It is a measurement of the resistance to airflow between the chambers of the collector.
