Key Features
- Explosion-proof enclosure for classified areas
- Carbon Monoxide specific electrochemical sensor technology
- 0-200 ppm factory range
- Electronics potted to eliminate internal corrosion
- Industry standard 24VDC, linear 4-20 mA output
- Operating temperature from -4°F to +122°F
- Accurately monitor CO levels for important action levels
- No false alarms from interference gases
- Real-time continuous monitoring for early CO detection
The GG-CO-EXP is designed for detection of carbon monoxide vapors in hazardous areas. The standard detection
range of 0-200 ppm provides real-time
continuous monitoring of concentrations accurately down to 20 ppm with
no false alarms.
The GG-CO-EXP utilizes a proven hydrogen sulfide specifc electrochemical
sensor for detecting poisonous CO gas
concentrations. No false alarms due
to cross-sensitivities from other gases,
and no false alarms from temperature
or humidity fluctuations.
The GG-CO-EXP provides an industry
standard linear 4/20 mA output signal
proportional to ppm concentration
of carbon monoxide. Long sensor life
with minimal span adjustment can be
expected in most applications. The
sensor is designed for simple calibration and the sensor head is easily field
replaceable.
Applications
- Food Processing areas
- Tank Rooms
- Parking Garages
- Bottling Plants
- Warehouses
- Ventilation Ducts
- Chemical Manufacturing
- Air Quality Monitoring
- Breweries
- Modified Atmosphere Packaging
Benefits
- Low cost explosion protection
- No false alarms from interference gases
- Simple operation & calibration
Carbon monoxide gas is approximately
the same weight as air and will mix
evenly with the air in all spaces. For
personnel protection, mount the sensor at a height in the breathing zone
of the employees. It would typically be
4 to 5 feet off the ground, which also
allows easy access. As a general rule of
thumb, try to mount sensors within 30
feet of potential CO sources.
The GG-CO-EXP is intended for horn/
strobe and ventilation activation, and
is also useful for alarm outputs such as
phone dialers and other alarm functions.
Typical sensor element life is 5+ years,
with only a 20:1 cross-sensitivity to
hydrogen. Field replaceable sensor
element keeps long term mainte-
nance simple and low cost. Every
circuit board is potted to completely
eliminate corrosion to the electronic
components and copper tracing on
the circuit board. An explosion-proof
aluminum enclosure houses the transmitter.
