| SHERLOCK OXYGEN
DEPRIVATION SENSOR (O2) was designed to
detect for the concentration of Oxygen
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 factory
calibrated to a sea level concentration of 20.9% oxygen clean air base zero level
at the factory prior to shipment. The O2
Sensor should be utilized as a signal
source for the SHERLOCK 2-SERIES or
SHERLOCK 4-SERIES REFRIGERANT GAS
MONITORING SYSTEMS. Typical
applications include:
- HVAC Chiller Equipment Rooms
- Refrigeration Mechanical Rooms
Features
ENCLOSURE -- NEMA 1 -
4.3"H x 3.4" x 1.2"D
ENVIRONMENT -- 50 to
95 °F (10 to 35 °C), 0 to 95 % RH non
condensing
POWER INPUT -- 12VDC,
250 mAmps
OUTPUT SIGNAL -- 0 to
5VDC
DETECTION RANGE -- 15%
to 25% Oxygen by volume
SENSITIVITY -- 0.5 %
of full scale reading
CALIBRATION -- Annually
WARM-UP TIME -- Readings
will stabilize after 3 hours.
- Can be read by the Sherlock
2-Series and 4-Series monitors
- Calibration is needed only once a
year.
- Reading Range: 15% to 25%.
- Long life time: expected 5 to 7
years at 20.9% Oxygen. Higher
concentrations will decrease life expectancy.
