A differential pressure transmitter is an instrument that senses a pressure difference between two points and converts the pressure to a standardized electronic signal which can be sent to a control element. The transmitter can be configured so that its signal is either proportional to a pressure differential, a flow rate, or a level.

The Low Range version of the differential pressure transmitter is designed to operate in a range going from a difference of 0 kPa (0 psi) to an absolute difference of 50 kPa (7.3 psi).

This Differential-Pressure Transmitter includes a transmitter which is compatible with the HART communication protocol.
