CO2 liquid switch - 90...240 V AC
CO2 - Sensor & Controls
HBSC2 is a level switch for detecting liquid CO2 in refrigeration systems. Typically, it is installed in/on the receiver, but it is also suited for installation in other locations where a level indication is needed. The sensor’s measurement principle makes it unique for these purposes, since the properties of the measurement principle as well as its special construction allows it to withstand high pressure and low refrigerant temperatures. The sensor is suited for use on transcritical CO2 refrigeration systems.
The switch has a built-in local power supply for direct use on net supply 90…240 V AC. A solid state relay can also operate a valve directly.
