The Edgetech Instruments SENTRY is a compressed air monitor and alarm system that senses both dew/frost point and pressure in industrial compressed air systems and activates two alarm functions giving visible and audible indications if either parameter goes out of user configurable limits.

The SENTRY features a strobe lamp and pulsing horn plus an alarm relay contact that activate when a programmable, low pressure or high dew/frost point alarm trip point is detected. Either condition triggers the alarms. It also has a local display of the measured pressure and dew/frost point of the compressed air system plus 4 to 20 mA analog outputs, one each for measured pressure and dew/frost point at atmospheric pressure. The SENTRY is a complete system, ready for out-of-the-box installation.

The SENTRY is easy to install using the Compressed Air Module (CAM). The CAM comprises an industrial ball valve, probe sample chamber and outlet valve at the compressed air sample point. Closing the ball valve isolates the probe sample chamber from high pressure air for service or inspection.
