KM3701 | 1-channel differential pressure measuring terminal -100…+100 hPa (-100…+100 mbar)

The KM3701 pressure measuring terminal enables direct measurement of pressure differences between two hose connections. The pressure difference is available in the fieldbus as a 16 bit value and can be measured between any points up to an ambient pressure of 10 bar. The status LEDs indicate proper function or errors such as over-range.
