The Edgetech SENTRY Compressed Air Monitor features a smart multi-sense probe that continuously monitors the dew/frost point and pressure of compressed air systems to detect compressor or dryer failures and system pressure leaks. 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.

Applications for the SENTRY include:

• Compressed air headers
• Point of use compressed air
• Dry air systems for critical process
• Monitoring fluidized bed dryers
• Monitoring instrument air systems
• Pharmaceutical packaging
• Laboratories and clean rooms
• Sensitive product storage
• Monitoring purge delivery systems
