* For installation with heating element.
Otherwise, the minimum temperature is – 30°C.
All terminals are protected against improper termination with a supply voltage up to 40 V. If
the supply voltage is greater than 40 V the electronics will be damaged
Function
HBSR is a level switch for detecting common refrigerants, including NH
for oil return management in ammonia refrigeration systems.
Typically it is installed in/on the receivers, pump separators, economisers, heat exchangers, or as an oil-
accumulation-sensor on ammonia systems.
The sensor differentiates between refrigerant, gas, and oil, so that the electrical signal from the sensor
changes when the liquid level drops below/rises above the level that it was installed at.
The sensor is calibrated to switch in the centre of the sensor's cylindrical part, with a hysteresis of about 1
mm.
When the refrigerant is on the same level or above this point, 4 LEDs light up (irrespective of the output
relay NO/NC).
