Product Description

Brief introduction
1. This model intelligent pressure switch is a kind of intelligent digital pressure control products
2. It integrate pressure measurement, LED display and control. 
3. It is complete electronic structure, the former adopt pressure sensor which is diaphragm, oil fulfill and piezoresistive type. 
4. Application: Measure the gas and liquid. Suit for pump control, tank monitoring, level control, filter plug, monitoring, leakage monitoring. Also it widely used in hydraulic and pneumatic situation, like mechanical facility and process control. 

Main features
1.4 digits display the current pressure value, pressure preset switch point and delay switch output.
