Description
weFlux2 pressure sensors measure the relative pressure of any desired media in closed systems. The pressure acting upon the sensor is converted to an electronic signal. The analog outputs read out the measured pressure and temperature values as 4 to 20 mA signals.
Features at a Glance
- Pressure and temperature measurement with a single sensor
- Compact, laser-welded stainless steel 316L housing
- 2 analog outputs: 4 … 20 mA
- Temperature-compensated pressure measurement
