Model APGT43.100, APGT43.160 Absolute Pressure Gauge

Brand: WIKA Instruments Ltd.
The model APGT43 intelliGAUGE® (patent, property right: e.g. DE 202007019025) can be used wherever pressure measurement has to be independent of fluctuations in the atmospheric pressure. 

The instrument serves for the on-site display with a simultaneous signal transmission to a central control or remote centre.
Features
  • No configuration necessary due to “plug-and-play”.
  • Scale ranges from 0 … 25 mbar absolute pressure.
  • Easy-to-read Analog display with nominal sizes 100 and 160.
  • High overload safety, long service life due to metallic media chamber sealing.
  • Media chamber protected against unauthorised access.
