Bourdon Tube Pressure Gauge with Electronic Pressure Switch - PGS25

Brand: WIKA Alexander Wiegand SE & Co. KG

The robust model PGS25 switchGAUGE is a combination of a Bourdon tube pressure gauge and a pressure switch. 

It offers the usual analogue display, which enables reading the process pressure on site, and in addition the possibility to switch up to two electrical signals.

The switch contacts are factory-set in a range between 5 % and 95 % of the scale range.
Features
  • Non-contact sensor (wear-free). 
  • Robust stainless steel case. 
  • Scale ranges 0 ... 1.6 bar to 0 ... 400 bar. 
  • NPN or PNP switching outputs. 
  • Both switch points factory-programmable between 5 % and 95 % of the scale range.
