1.2 Application
The Sentry environmental monitoring system can be stored for long periods of time
in refuge chambers or confined spaces ready for immediate use if an emergency
event occurs. Plug-in pre-calibrated gas sensing eModules will then continuously
monitor a range of four atmospheric gases, operating a clear display of current and
historic accumulated data of all the measured gas concentrations. A waterproof
Navigation Keypad gives direct access to the information:
• Instantaneous gas concentration display
• Detail information display of each gas sensor
• Minimum and maximum readings reached
• Trend analysis
• 4000 points of data logging with time and date stamp
Inbuilt audio/visual alarms provide discrete alerts of gas concentration levels
exceeding factory configured thresholds. The Sentry is powered by a detachable
12 V dc rechargeable battery that will power the environmental monitoring system
for more than 192 hours. A manual gas pump operated gas manifold is temporarily
attached when specific measurement samples need to be taken from outside the
immediate area.
Sentry is housed in a robust shockproof housing and is dust and moisture proof up
to IP65 standards with integral EMC protection. Safety latches enable the front and
rear halves to be quickly disassembled for maintenance and ease of transport.
