Description
weFlux² two-wire pressure sensors with analog output are distinguished by their space-saving design and a short response time of less than one millisecond, making them ideally suited for quick pressure measurement applications – for example when monitoring pressure curves in hydraulic systems. Thanks to the temperature element integrated in the measuring cell, the sensors with a G3/4″ flush-mounted process connection are equipped with accurate temperature compensation.
Features at a Glance
- Compact, laser-welded stainless steel 316L housing
- Analog output: 4…20 mA
- Precise measuring accuracy: ±0.5%
