Bourdon Tube Pressure Gauge with Switch Contacts - PGS21.100, PGS21.160

Brand: WIKA Alexander Wiegand SE & Co. KG

Wherever the process pressure has to be indicated locally and, at the same time, circuits need to be switched, the model PGS21.1x0 switchGAUGE finds its use.

Switch contacts (electrical alarm contacts) make or break circuits dependent upon the pointer position of the indicating measuring instrument. The switch contacts are adjustable over the full extent of the scale range (see DIN 16085), and are mounted predominantly below the dial, though also partly on top of the dial.

The instrument pointer (actual value pointer) moves freely across the entire scale range, independent of the setting.

The set pointer can be adjusted using a removable adjustment key in the window.
  • High reliability and long service life.
  • Up to 4 switch contacts per instrument.
