ESS201 Intelligent Pressure Switch
ESS201 Series Intelligent Pressure Switch is an intelligent digital-displayed product for pressure testing & controlling. It integrates functions of measuring, display, output and control all in one. It has a complete electronic structure. Oil-filled piezoresistive pressure sensor with diaphragm is applied in the front part. The output is processed by high-precision and low-temperature drift amplifier, then transformed by high-accuracy A/D converter into digital signal that could be processed by MPU(Micro Processor Unit).The processed signals control two switches then to test & control the pressure.
With flexible application, simple handling, easy debugging and high reliability, this product is widely employed to test & control the pressure of fluid medium in many industries including areas of hydroelectricity, city water, oil, chemical, machinery, hydraulic system etc
