IR SENSOR
(Also see manual 44-0295 IR Sensor (44-0221 Obsolete)
The SHERLOCK Non-Dispersive IR Refrigerant Gas Sensor
was designed to monitor for the presence of refrigerant gases
within an enclosed space. The sensor is mounted within the
space to be monitored and connected by cable to a SHERLOCK
System. The IR sensor is calibrated to a specific refrigerant
gas. The IR comes in two Temperature ranges depending upon
the monitoring environments: Machine room and Extended for
refrigerated applications in NEMA 3R Aluminum (Pictured).
Water-tight ABS fiberglass housing for Wash down protection
(NEMA 3R) and Stainless Steel enclosure are also available.
The IR Sensor is a reliable method of monitoring for refriger-
ant gas leaks in environments that have air quality problems.
The IR will eliminate many false alarms in environments that
contain gasoline, diesel, and propane exhaust and fumes from
solvents, paints, cleansers, and others.

APPLICATIONS
Typical applications include:
Wineries
Bakeries
Refrigerated Rooms
WARNING!!!! The infrared sensor is not to be
applied into all refrigerated storage applications
where other toxic gases are used in the same room.
Some installations are not suitable for Infrared
technology. Misapplication may result in damage
to sensor. Contact the factory for a specific list of
approved applications.
