OxyDetect Oxygen Deficiency Gas Detector
2
05311001B / Revision 4
1.3
Description
The Instrument is a fixed wall mounted gas detector with an integral oxygen sensor
that outputs a linear 4-20mA signal that represents an ambient oxygen concentration.
Additionally, three changeover relays are provided to signal the following detector
statuses.
Measurement alarm level 1 (user configurable)
Measurement alarm level 2 (user configurable)
Instrument Fault and Oxygen measurement >23%
These outputs must be integrated into a gas detection management system as the
instrument gives no direct visible or audible warning or alarm of an oxygen-deficient
environment (internal audible alarm or visual beacon), its function being solely to
measure the ambient level of oxygen. It offers a measurement of ambient oxygen
based on the principles of paramagnetism, a non-depleting and inherently linear
measurement technique.
The instrument is designed to be installed within indoor working environments such
as laboratories, workshops or analyser shelters.
Gas sample measurements are shown on the instrument display, and can be output
as a 4-20mA milliamp (mA) signal and / or gas sample alarm levels indicted by relay
status, to a gas detection management system.
The instrument requires little routine maintenance, other than calibration which is
essential for the accuracy of the gas measurements.
The instrument is not to be used for process control or process
monitoring
L'instrument ne doit pas être utilisé pour le contrôle des
processus ou la surveillance de processus
The OxyDetect is not a medical device as defined in the medical
devices directive 93/42/EEC and is not intended to be used on
human beings for the diagnosis, prevention, monitoring,
treatment or alleviation of disease. Injury or replacement or
modification of the anatomy
