QYK102 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.

1. 4 digital figures display current pressure values.

2. Pressure preset switching points and delay switch output.

3. The switch can be set into any figures from zero to full values.

4. The shell is provided with joint action light-emitting diode, convenient for observation.

5. The key can adjust and set various parameters conveniently.

6. Two-way switch output, 1.2A loading capacity.

7.analog output is 4~20mA.
