How to Specify a
Computerized Gas Monitoring System
1 *) Select sensors by gas and type. Select sensor
accessories. Are dust covers or
splash guards required?
2 *) Select a transmitter (by gas) and a explosion proof housing, one
for each sensor.
3. Count the number of sensors you have chosen.
i. Decide how big a system you need, allowing for expansion. Choose that Sage
system. It will include everything that you need including: Computer(s) with VGA
display, keyboard, mouse, printer, base station radio, microphone, portable
radio, and owners manuals with local relays, power supply, and watch dog timer.
ii. Decide how many areas you will want to monitor gas in. Order one sensor

relays at the computer console. Relay satellites can be added at any time.
