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. Preset temperature switch
