| SHERLOCK CERAMIC METAL
OXIDE SEMICONDUCTOR REFRIGERANT GAS
SENSOR (CMOS) was designed to detect for
the presence of refrigerant gas within an
enclosed space. The sensor is mounted
within the space to be monitored and
connected by cable to the monitoring
control system. 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 the
SHERLOCK 2-SERIES or SHERLOCK 4-SERIES
REFRIGERANT GAS MONITORING SYSTEMS or the
WIZARD EVAPORATOR CONTROL SYSTEM. The
CMOS Sensor is an economical method of monitoring for refrigerant gas leaks in
environments that do not normally have
air quality problems. The CMOS sensor
will false alarm in environments that
contain gasoline, diesel, and propane
exhaust and a number of solvents or
cleansers.
Typical applications include:
- HVAC Chiller Equipment Rooms
- Refrigeration Mechanical Rooms
- Refrigerated Rooms
