GG-CO2
General Description
Installation
The GG-CO2 sensor is a +24 VDC, three-wire, 4/20
mA sensor for carbon dioxide which utilizes proven
infrared sensor technology for accurate and reliable
leak detection. The 0-3% (0-30,000ppm) detection
range of the GG-CO2 provides real-time continuous
monitoring of ambient carbon dioxide concentrations.
0-1% and 0-5% ranges are also available.
The GG-CO2 provides an industry standard linear 4/20
mA output signal compatible with most gas detection
systems and PLCs. The output signal is not affected
by drastic temperature and moisture variations that
occur during washdown, defrost cycles, etc.
The circuit board is sealed in potting compound,
completely protecting sensitive electronic components
and copper tracing from corrosion. The specially
vented chemical-resistant polycarbonate enclosure
protects the sensor from accidental damage, weather
and direct hose-hits from cleaning crews.
Locating the sensor
One of the most important considerations when
installing GG-CO2 sensors is that they must be easily
accessible for calibration and maintenance.
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 about five feet off the ground, which also allows
easy access. As a general rule of thumb, try to mount
sensors within 30 feet of potential leak sources.
