Midas
®
uses patented Honeywell Analytics technology
to continuously monitor the health check status of
specific electrochemical cells and alert the user if a
cell enters a variety of fault conditions (such as open
or short circuit etc.) which would leave the cell unable
to detect gas and raise an appropriate alarm signal.
REFLEX
®
overcomes this unseen failure mode by
applying periodically a special electronic pulse
to the cell and reviewing the ‘echo’ from the cell
as it responds to the applied signal. If the cell is
deteriorating within certain pre-set limits based on
the received signals then Midas
®
will decrease the
REFLEX
®
sampling interval in order to establish the
actual viability of the cell. Within a relatively short time,
Midas
®
will be able to alert the user via fault codes
that the electrochemical cell is likely to be requiring
replacement and is possibly unable to correctly detect
gas.
REFLEX
®
is not required for pellistors or oxygen
electrochemical cells as these sensor cartridges
provide alternative electronic means to indicate open
circuits and other sensor cartridge damage issues.
