KM3702 | 2-channel absolute pressure measuring terminal 7,500 hPa (7.5 bar)


The KM3702 pressure measuring terminal enables direct measurement of two pressure values at the hose connections. The pressure is determined as a pressure difference to the ambiance of the KM3702 and is available in the fieldbus as a 16 bit value. The status LEDs indicate proper function or errors such as over-range.
