The DCC-MRI is a self-contained Oxygen sample draw 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.
Because the strong magnetic field inside MRI and NMR rooms can interfere with electronic equipment installed inside the room, the DCC-MRI gas detection 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 DCC-MRI will go into alarm.
The DCC-MRI comes with an O2 sensor (measurement range 0 - 25% volume), a flow detector, a sample draw pump and an internal adjustable flow meter. Features include one configurable 4 - 20 mA 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 side mounted audible buzzer and an LCD 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.
