Key Features
- Explosion-proof enclosure for classified areas
- Sulfur dioxide selective electrochemical sensor technology
- 0-20 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 SO2 levels for personnel protection
- No false alarms from interference gases
- Real-time continuous monitoring for early leak detection
The GG-SO2-EXP is designed for detection of sulfur dioxide gas in hazardous
areas. The standard detection range of
0-20 ppm provides real-time continuous monitoring of concentrations accurately down to 1 ppm with no false
alarms.
The GG-SO2-EXP utilizes a proven
sulfur dioxide specifc electrochemical sensor for detecting toxic SO2 gas
concentrations. No false alarms due
to cross-sensitivities from other gases,
and no false alarms from temperature
or humidity fluctuations.
The GG-SO2-EXP provides an industry
standard linear 4/20 mA output signal
proportional to ppm concentration
of sulfur dioxide. 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
- Wineries
- Perimeter Monitoring
- Refineries
- Wastewater
- Heat Treatment
- Process manufacturing
- Refrigeration systems
- Air quality
- Textiles
Benefits
- Low cost explosion protection
- No false alarms from interference gases
- Simple operation & calibration
Sulfur dioxide gas is twice as heavy as
air and will tend to accumulate in lowlying 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 SO2 sources.
The GG-SO2-EXP is useful 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.
