Differential pressure transmitter is measuring transducer at both ends of the pressure difference transmitter with standard output signals (such as 4 ~ 20mA, 0 ~ 5V). Difference between differential pressure transmitter and pressure transmitter is they have two pressure interface, differential pressure transmitter generally positive pressure and negative pressure ends, under normal circumstances, the differential pressure transmitter is a positive voltage terminal pressure should be greater than the negative pressure to measure.

 Remote pressure differential pressure transmitter is to know the pressure measured by a remote device mounted on a pipe or vessel.

Pressure by the capillary filling silicone oil ( or other liquid ) is passed to the main transmitter.
Throw the line amplifier board the pressure and differential pressure is converted into 4-20 mA DC signal.
Remote pressure differential pressure transmitter with intelligent amplification board combination may constitute intelligent remote pressure differential pressure transmitter.
The software running on PC has been designed to calibrate and adjust the circuit by software for sake of debugging the transmitter conveniently.
The calibration is done through the industry-standard HART communication method.
