Manufacturer 4~20mA LED 4 Digits Display Smart Pressure Switch

Product DescriptionQYK102 Smart Pressure Switch is an intelligent LED displayed product for 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 used  in test & control the pressure of fluid medium in many industries including areas of hydroelectricity, city water, oil, chemical, machinery, hydraulic system etc. 1. 4 digits display2.
