LW4/5 incorporate a Hall-Sensor to measure liquid level of refrigerants and oil
in liquid receivers, oil separators, flash tank and oil reservoirs. A magnetic float
changes its position according to the liquid level. The hall sensor converts these
magnetic field changes into an equivalent signal, which is used by the internal
electronic to show with the LEDs the status of liquid level. If the level reaches
certain level range (high or low level range), LW illuminates RED LED and
activate a SPDT contact. If the liquid level comes back to normal level range, the
Green LED illuminates and the contact switch back.
Notes:
LW4 is developed for HFC refrigerants, subcritical CO
