GENERAL
(See manual 44-0283 CMOS Sensor for more) SHERLOCK
CERAMIC METAL OXIDE SEMICONDUCTOR (CMOS)
REFRIGERANT GAS SENSOR was designed to detect for
the presence of a refrigerant gas within an enclosed space.
The sensor is mounted within the space to be monitored and
connected by cable to the monitoring device. Each sensor is
calibrated to a clean air base zero level at the factory prior to
shipment. There are three models of the CMOS sensor, one for
CFC/HCFC gases, one for HFC gases and one for Ammonia.
The CMOS Sensor should be utilized as a signal source for a
SHERLOCK Refrigerant Gas Monitoring System.
APPLICATIONS
Typical applications include:
Refrigerated Rooms
Wineries
Bakeries

LIFE EXPECTANCY
NOTE: These sensors, due to their nature, are susceptible
to detection of non-refrigerant gases and cannot distinguish
the presence of different refrigerant gases, only that there is
a gas present. The CMOS sensor will detect concentrations
of gasoline, diesel, and propane exhaust and fumes from
solvents, paints, cleansers, and others (Please call Genesis
Customer Support for more information.)
accuarcy is a best case and some refrigerant blends can be
off as much as 100% of the Sherlock Control ppm reading.
NOTE: The stated life expectancy for this sensor is 3 to
5 years, however, continued exposure to refrigerants and
other gases and humidity and other adverse conditions can
severely decrease sensor life.
