Flygt's monitoring unit, 83 58 40, is designed for use in
pumps from model 3231 and larger models equipped
with drive units 680-945. Turbines equipped with
generators 705-935 are also covered by the monitoring
system.
The monitoring unit is connected to the standardized
range of sensors incorporated in all the products
covered.
Channel A, liquid level
This channel is used, for example, for monitoring of
possible liquid leakage into the stator casing. A sensor
is incorporated in the lower part of the stator casing.
The sensor changes resistance from about
1.5 kΩ to about 330 Ω if liquid enters.
Another sensor that can be connected to this channel
is the water in oil sensor, called CLS (capacitive
leakage sensor). The CLS-30 monitors the content of
water in the oil housing or the gear box and alarms at
a percentage > 35.
