Where
should the sensors be located?
This is the single most asked question of General
Monitors. Unfortunately, there are no hard and fast
rules for this since there are so many variables
that must be taken into account.
The following guidelines should be considered: 1.
The vapor density or relative weight of gases: Sensors
should be located near the floor for gases or vapors
three or four times heavier than air. They should
be installed near the ceiling or roof to detect
lighter than air gases.
2.
Ignition sources: Sensors should be located between
a potential leak source and a source of ignition,
preferably closer to potential leak sources.
3.
Air currents: The general guideline is to locate
the sensor where the prevailing air currents contain
the maximum concentration of the gas being monitored.
4.
Dispersion of gas: Generally, sensors should not
be far removed from any potential source of escaping
gas. Liquids of low volatility, in particular, require
the location of the sensor in the immediate area
of the vapor source. Liquids with high flash points,
or slow rates of dispersion may produce a low reading
if the sensor is any distance from the spill or
break.
5.
Temperature limitations: All sensors have ambient
temperature limitations and the installation of
the sensor must be within the specified range.
6.
Vibration: Vibration may be damaging to the sensor
and must be considered in selecting the sensor location.
In general, this means anchoring the sensor to a
wall or firm base rather than to a motor housing.
7.
Wiring: Good instrument wiring practices should
be incorporated in the sensor installation, and
wiring separate from other AC wiring.
8.
Accessibility: Since it is desirable to calibrate
on a periodic basis, sensors should be installed
in a location permitting reasonable access.
9.
Moisture protection: Sensors should be mounted where
they are protected from immersion or direct contact
with water.
10.Dust protection:
Sensor dust covers should be used if sensors are
mounted in dirty or dusty environments. Do you have
electronic copies of manuals for discontinued parts
available for download?
Yes. Scanned copies of manuals for discontinued
parts may be found in our Customer
Care Center. Does General
Monitors have a Waste, Electrical and Electronic
Equipment (WEEE) procedure?
Yes, any products manufactured by General Monitors
requiring WEEE disposal within the European Union
shall be returned from the customer to our local
European distributor. The local European distributor
shall return any collected WEEE quarterly
to General Monitors Ireland at General Monitors'
expense. General Monitors Ireland shall be responsible
for treatment, recycling, recovery and proper disposal
of WEEE.
