SENTRY - Compressed Gas Alarm System - OVERVIEW
by EdgeTech Instruments

The SENTRY-Series Compressed Gas Alarm System is designed to detect low pressure or high dew point conditions within compressed air / dryer systems. It is typically installed at the main compressor/ dryer header, but in many moisture sensitive processes, the SENTRY is also installed at the point of use.

The SENTRY is similar to the SENTINEL Humidity Measurement Transmitter in that they both incorporate a sensor control display module with the four-measurement parameter capability of the HP125 Series Humidity Probe (RH, Temperature, Pressure and Dew Point).  The SENTRY adds audible and visual alarm functionality.
