Description
The weFlux²micro miniature pressure sensor with analog output is distinguished by its space-saving design and low weight. This enables precise pressure measurements in confined installation spaces and on moving plant components such as robot arms. The short response time (<1 ms) allows the sensor to be implemented in quick pressure measurement applications – for example, when monitoring pressure curves in hydraulic systems.
Features at a Glance
- Compact, laser-welded stainless steel 316L housing
- Analog output: 4…20 mA
- Very fast response time of < 1 s
- Very low weight at 13 g (without cable)
- Very small format at Ø 14 mm, SW13
