Product introduction

The PN70 series of electronic pressure sensors utilise a high precision diffusion silicon core to ensure high accuracy and durability. With field display, LED digital display of the field pressure or setting menu.
Maximum measuring range: -1...600 bar. .600 bar, digital LED display of pressure value and switching status, menu setting of switching point, analogue start and end points, output function, memory function and display function, so that setting does not need to be done on site. Highly reliable, the output can be used directly for PLC, M12 locking type connector, easy to disconnect, high degree of protection. Positive or negative pressure can be measured. With both switching and analogue outputs, the sensor can be used as both a pressure switch and a pressure transmitter.
