1.0 Introduction
The ETS-Lindgren Sample Draw Oxygen Monitoring System (OMS™) is a
self-contained oxygen deficiency detection system suitable for remote sampling
of confined spaces; this single-point monitor is designed for the continuous
detection and measurement of ambient oxygen concentration levels.
As a compact gas monitoring system, the OMS is ideal for the continuous
monitoring of the air in MRI rooms, labs, freezers, confined spaces, and other
shielded enclosures where inert gases may displace the oxygen and create a
danger for patients and staff. The OMS is suitable for indoor and outdoor use,
and is intended to be installed outside of the shielded enclosure.
Each system consists of a long-life zirconium oxide sensor cell and 3-wire
transmitter. Unlike electrochemical sensor cells, the zirconium oxide sensor cell
provides stable oxygen readings even in areas where temperature and humidity
levels are changing. The OMS may be used as a standalone gas detector or
connected to your own centralized control and surveillance system.

The heart of the monitoring system is a zirconium sensor, which responds to low
oxygen conditions within seconds and provides accurate measurements over a
wide temperature and humidity range. The zirconium sensor will operate
continuously for eight or more years, requiring minimum maintenance. There are
no zero or span calibration pots to adjust, and when compared to disposable
sensors, the long-life zirconium sensor can save hundreds of dollars in annual
maintenance.
Unlike concentration cells, the zirconium sensor does not need an oxygen
reference gas for proper operation. The OMS can detect low oxygen levels in
confined spaces and process tools without the need of a reference gas.
