In extractive gas analysis the sample gas must be conditioned
before it enters the measuring cell of the analyser. One of
these conditioning stages is moisture precipitating in so-
called sample gas coolers. Since the composition of the sample
gas can fluctuate, a condensate slip downstream from the
cooler cannot be entirely ruled out. Moisture detectors
installed in the cooler output indicate such slip. Combined
with suitable controllers this will generate the respective
signals/alarms in the control system.
The moisture detector series features a wide range of options.
FF-HM series for rail mounting:
Connect up to two parallel moisture detectors or one
moisture detector
Potential-free outputs for moisture alarm and cable break
on standby current (fail-safe).
LEDs for voltage, moisture and cable break.
Fault analysis settings: auto-reset or lock.
FF-x-U series inside a small casing:
Auto-resetting alarms, based on open circuit principle.
LEDs for voltage, moisture and cable break.
