Page 4: General Description
GG-CO2 General Description Installation Locating the sensor The GG-CO2 sensor is a +24 VDC, three-wire, 4/20 mA sensor for carbon dioxide which utilizes proven One of the most important considerations when infrared sensor technology for accurate and reliable installing GG-CO2 sensors is that they must be easily leak detection. -
Page 5: Installation Guidelines
GG-CO2 Installation Guidelines: • Always mount the sensor vertically. 6.5" • Must be easily accessible for calibration and 2.0" maintenance. • Mount the sensor close to the potential leak source. • For optimum personnel protection, mount sensor in the “breathing zone” (4’ – 5’ above floor). -
Page 6: Wiring
GG-CO2 Wiring Electrical wiring must comply with all applicable codes. Electrical Power: 24 VDC regulated, 350 mA. Output: Linear 4/20 mA output. Monitoring equipment may have a maximum input impedance of 700 ohms. Cable Recommendation: 20/3 shielded cable (General Cable C2525A or equivalent). Length of cable to sensor should be no greater than 1,500 feet. -
