LECTRONICS
The OMS incorporates a special electronic circuit that continuously monitors
sensor operation. With the addition of the alarm relay option, any cell degradation
or complete failure will be detected immediately. This smart circuitry alerts the
user to sensor faults and other electrical problems that may interrupt surveillance
through the standard mA signal output signal or through the optional fault relay
option.
Ideal for continuously monitoring oxygen levels in confined spaces or areas
where inert gases are used, the OMS does not drift or lose sensitivity with
weather or temperature changes. The electronics are housed in a
NEMA Type 4X enclosure.
Standard Configuration
The OMS must be installed outside of the shielded enclosure.
