Examples of usage
The HBSR switch is well suited to be used for
-
Indication of high and low refrigerant levels in liquid separators, pump separators, economisers,
and inter coolers.
-
on/off control of liquid injection in liquid separators, pump separators, economisers, and inter
mediate coolers
On ammonia refrigeration systems, it can also be used for
-
Indication of accumulated oil in oil sumps, oil pots, liquid separators, economisers, inter mediate
coolers. It is used here with a reversed contact function for automatic oil discharge/drainage.
Installation instructions
The following applies during installation:
1)
Where the sensor is installed in a threaded sleeve/pipe stub, this should be welded at a 5-10°
upwards angle
relative to the horizontal, so as to prevent the formation of liquid pockets.
2)
The installation length of the sensor must be taken into account, since there must be at least
2mm between the sensor's mechanical part and other fixed or moving parts.
