PM710 is an intelligent digital display pressure measurement and control product integrating pressure measurement, display, output and control. The product has a fully electronic structure, and the front end uses a silicon piezoresistive pressure sensor. The output signal is amplified and processed by a high-precision, low-temperature drift amplifier, sent to a high-precision A/D converter, processed by a microprocessor, and displayed in the field. And output 2 switching values to detect the pressure of the control system.
CHARACTERISTICS:
1,High switching accuracy
2,Adjustable response time
3,NPN, PNP compatible, freely switchable
4,Button adjustment, one click for quick zero adjusting,quick unit switching
5,OLED display current pressure
6,Node action with luminous tube, easy to observe
