Edgetech Instruments SENTRY Designed Specifically as a Compressed Air Monitor and Alarm System

May 18, 2017

The new Edgetech Instruments SENTRY is designed specifically as a compressed air monitor and alarm system. It senses both the dew/frost point and pressure in industrial compressed air systems and activates two alarm functions giving visible and audible indications if the compressed air dew/frost point increases or pressure decreases beyond user configurable set points.

Using a Smart Multi-Sense Probe to continuously monitor both parameters, the probe is inserted into the pressurized compressed air stream giving immediate warning of a system leak or failure of an air dryer or compressor. The Sentry’s highly visible strobe light and highly audible pulsing alarm activate if the air system goes out of predetermined ranges.

The SENTRY is easy to install using the available 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. The CAM provides a ¾ inch NPT female fitting for simple and safe connection to the compressed air system. Using the CAM, measurements can be made either at full line or atmospheric pressure by adjusting the CAM’s inlet and outlet valves. There is no need to depressurize the compressed air system for sensor maintenance.

The SENTRY with CAM is a turnkey alarm system, ideal for industrial compressed air monitoring and control, alerting personnel to upset air quality or pressure conditions quickly and reliably. It can be used to monitor utility source air for overall management as well as point of use air to protect sensitive processes or equipment.

Edgetech Instruments designs and manufacturers accurate and reliable absolute humidity hygrometers, relative humidity transmitters, humidity probes, dew/frost point analyzers, relative humidity calibrators, dew/frost point generators and oxygen measurement instrumentation. Edgetech products are designed,  manufactured and calibrated to the highest industry standards in a modern ISO 9001:2008 registered, ISO/IEC 17025:2005 accredited facility located in Hudson, Massachusetts. All calibrations are traceable to NIST
