DCC-MRI Oxygen Sampling System
Available from Critical Environment Technologies Canada Inc.
The DCC-MRI is an Oxygen (O2) monitoring system developed for Magnetic Resonance Imaging (MRI) room applications and other locations where compressed gases and cryogenic liquids are used. Nitrogen, helium and sometimes carbon dioxide when dispensed, will displace Oxygen, creating an Oxygen deficient or hazardous atmosphere.
Since electronic equipment does not operate well inside the MRI and NMR rooms due to the strong magnetic field, the DCC-MRI system is designed to be installed outside of the room with a sampling tube running from the monitoring system to the sampled environment. The sample draw pump pulls in the air, flowing it over the sensor and exhausts it through the outlet port. If the Oxygen level drops below a specified set point, the DCC-MRI will go into alarm.
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 digital display with LED indicators for channel alarm status and fault conditions.
The system is accurate enough to measure to government established exposure levels for O2 deficiency for health and safety.
