Product Description: QY Sealed Oil or Water Pressure Sensor


QST-201 series liquid level transmitters are consist of well-sealed immerging oil-filled liquid level transducers and special circuit for manometers . Have characteristics of high precision,good stability,long life and easy to fix. Adopt special sealed configuration,so with good capability of anti-leakage.

According the relation between pressure,density and liquid level, the liquid level transducers measure the liquid pressure which in direct ratio with depth of liquid, then via amplificatory circuit,the measured pressure is transferred to standard 4~20mA current signal(or standard voltage signal).

 

Feature:

1.Range:0~0.6 mH2O....0~200 mH2O

2.Sealed structure, IP68.

3.Accuracy: 0.1% FS, 0.25% FS(standard), 0.5% FS

4.There is two kinds of connector to be chosen: intracavity or flush membrane type

5.Integrated construction ,without external adjustment.

 

Dimensions: (unit:mm)
