The Edgetech Instruments Model SENTRY monitors conditions in compressed air systems for dew point and pressure at the system header or dryer output. The SENTRY alarms when a loss in pressure or high dew point is detected. This information is valuable in detecting compressor failures, system leaks, or drops in dryer performance. A pulsing audible alarm and strobe lamp provide quick notification of upset conditions. The SENTRY also provides a local display of pressure, dew point and system status as well as 4-20mA analog output and alarm relay contacts.

The Edgetech Instruments "SMART" Multi-Sense Polymer Probe is mounted into the pressurized gas stream and provides pressure and dew point analysis using a single penetration point into the process. Since the measurement is done at pressure, the SENTRY automatically pressure compensates the Dew Point calculation.
