AirLink 6940XP Operator’s Manual
Remote-Mounted Kit
A remote-mounted sensor kit can be ordered if the sensor needs to be somewhere that is not
conveniently accessible for viewing the display screen.
The kit includes a second junction box on a cable with a cable bushing/cable gland. The cable can
be ordered in 1-foot increments with maximum cable lengths listed below.
The cable and cable bushing/cable gland are not explosion-proof. If the assembly is installed in a
classified location, the cable bushing must be removed and replaced with explosion-proof
conduit. You must meet local electrical codes and use appropriate construction technique to
maintain the explosion-proof classification of the assembly.
Installation
This section describes procedures to mount the AirLink 6940XP in the monitoring environment
and wire the AirLink 6940XP.
Mounting the AirLink 6940XP
1. Consider the following when you select the mounting location:
• The unit should be placed greater than 6.5 feet/2 meters away from a monitor in order to
ensure reliable communications.
• Select a site where the AirLink 6940XP is not likely to be bumped or disturbed. Make sure
there is sufficient room to perform start-up, maintenance, and calibration procedures.
• Select a site that is representative of the monitoring environment and where the target gas
is likely to accumulate or where it is most likely to leak. The AirLink 6940XP should not
be installed near an entrance, air intake, or exhaust point.
• When monitoring “light” hydrocarbons, such as methane, the unit should be placed near
the ceiling or ceiling corner.
• When monitoring “heavy” hydrocarbons, such as gasoline, the unit should be placed
approximately 2 to 3 inches from the floor.
• The sensor must point down.
