Key Features
- Explosion-proof enclosure for classified areas
- Chlorine selective electrochemical sensor technology
- 0-5 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 OSHA's TWA & STEL levels for personnel protection
- No false alarms from interference gases
- Real-time continuous monitoring for early leak detection
The GG-CL2-EXP is designed for detection of chlorine gas in hazardous areas.
The standard detection range of 0-5
ppm provides real-time continuous
monitoring of concentrations accurately down to 0.5 ppm with no false
alarms.
The GG-CL2-EXP utilizes a proven
chlorine specifc electrochemical sensor
for detecting toxic chlorine gas concentrations. These toxic fumes can be
from storage tanks, sanitizing or other
sources. No false alarms due to crosssensitivities from other gases, and
no false alarms from temperature or
humidity fluctuations.
The GG-CL2-EXP provides an industry
standard linear 4/20 mA output signal
proportional to ppm concentration of
chlorine. 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
- Compressor Rooms
- Tank Rooms
- Cold Storage
- Refrigeration System
- Sea Vessels
- Pulp and Paper
- Heat Treatment
- Chemical Plants
- Breweries
Benefits
- Low cost explosion protection
- No false alarms from interference gases
- Simple operation & calibration
Chlorine gas is more than twice as
heavy as air and will tend to accumulate in low-lying areas in poorly ventilated rooms. For optimum personnel
protection (representative concentration reading that an employee would
be exposed to), mount the sensor at
a height in the breathing zone of the
employees. It would typically be no
higher than 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 CL2
leak sources.
The GG-CL2-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 3 years,
with minimal cross-sensitivity to
other gases. Field replaceable sensor element keeps long term maintenance 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.
