差压变送器是测量变送器两端压力之差的变送器,输出标准信号(如 4-20mA、0-5V)。差压变送器与一般的压力变送器不同的是它们均有2个压力接口, 差压变送器一般分为正压端和负压端,一般情况下, 差压变送器正压端的压力应大于负压段压力才能测量。
Sensys DPB model is ideal for the application (such as HVAC) with differential pressure, vacuum pressure, gauge pressure and especially low pressure of non-corrosive gases or air measured. Device for Low Pressure Gauge / Switch, which is using MICOM, improved Accuracy. Analog output 4-20mA, 2wire and it provides LCD display.
