CTS差压压力表主要用来检测两个检测测点压力的差值，仪表采用弹簧管作为测压元件，不同压力的介质分别进入弹簧管内，弹簧管产生位移，经过机械传动机构，直接从仪表度盘上指示出差压值。广泛应用于机械、冶金、石油、化工、电力和水利等行业。
CTS Differential Pressure Gauges are intended for measurement of a pressure differential that exists across two pressurized media of a system. Two Bourdon tubes are used to measure the jpressure of two points of a system according to a mechanical device a pressure differential can be indicated. It is widely used in mechanical、 metallurgy、 petroleum、 chemical industry and so on
