The model PGS21 switchGAUGE is a combination of a Bourdon tube pressure gauge and a pressure switch.
It offers the usual analogue display, which can be read on-site irrespective of the power supply, and in addition the possibility to switch a potential-free electrical signal.Features
- High switching reliability and long service life.
- Design per EN 837-1.
- Switch contacts fixed to customer requirements.
- Increased ingress protection IP 65.
