SENTRY Compressed Air Monitor and Alarm

Product Description

The Edgetech Instruments Model SENTRY detects upset conditions in compressed air systems by constantly monitoring 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.

 

An Edgetech 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.

The SMART sensor probe features a replaceable sensor tip that is factory calibrated and is provided with a NIST Traceable certificate. There is no need to send the probe back to the factory for calibration. Simply replace the sensor tip on-site! Save transportation costs and downtime by using tip replacement. The SENTRY system will recognize the new tip and automatically reset the system to accept the new calibration data stored in the sensor tip electronics. The sensor tip comes with a NIST traceable certificate for your quality records. Save time and Money!
