Brief Introduction

Differential pressure transmitter/pressure transmitter  is a measure of the difference between the two ends of the transmitter ,output standard signal ( 4 ~ 20mA) 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.
