CGAS-SD-CO | Critical Environment Technologies | Gas & Specialty Sensors

The CGAS-SD-O2 is a self-contained Oxygen (O2) monitoring system is designed for use in rooms where compressed gases are used, such as in MRI and NMR rooms. Compressed gases and cryogenic liquids (usually nitrogen, helium and sometimes carbon dioxide) when dispensed, will displace Oxygen, creating an Oxygen deficient or hazardous atmosphere. Continuous monitoring of the Oxygen levels in these rooms is recommended to ensure the Oxygen levels remain safe and people inside the rooms are alerted in the case of a gas leak situation. In addition, the strong magnetic field inside MRI and NMR rooms can interfere with electronic equipment installed inside the room. The CGAS-SD-O2 system is designed to be installed outside the room, with sample tubing running from the monitoring system to the sampled environment. The air in the room is continuously drawn into the device by the sample draw pump, flowing over the sensor and is exhausted through the outlet port. If the Oxygen level drops below a specified set point, the cGas-SD will go into alarm. The CGAS-SD-O2 comes with an O2 sensor, a flow detector, a sample draw pump and an internal adjustable flow meter. Features include one field configurable milliamp or voltage output, one alarm level line voltage relay with field configurable time delays and trigger levels, a blocked flow alarm indicating a dirty filter or clogged tubing, a door mounted audible buzzer and an LCD digital display with LED indicators for channel alarm status and fault conditions. This system is accurate enough to measure to government established exposure levels for O2 deficiency for health and safety.
