VISY-Reed Interstitial
The leak detection sensor for
double-walled tanks with reed switch
VISY-Reed Interstitial sensors
detect liquids in the intermediate chamber of double-walled
tanks. The level of the liquid is
monitored and an alarm will be
released when the threshold has
been passed.
VISY-Reed Interstitial is available
as ”Dry“ type for dry intermediate chambers and as ”Wet“ type
for intermediate chambers filled
with liquid.

VISY-Reed Interstitial Dry,

Function description
VISY-Reed Interstitial sensors
combine simple float switches
based on reed contacts with the
VISY-Sensor interface for connection to the VISY-Command.

The float follows the level of
the liquid as it rises, and a magnet opens a reed switch inside
the sensor tube. This alarm
message is transmitted directly

to VISY-Command. Thanks to
the low power input, VISY-Reed
sensors of different types can be
operated parallel to a VISY-Stick.
