Technical data: HBSC2
The HBSC2 is a Level Switch designed for detecting liquid CO2 in refrigeration systems. It can also be used to detect butane, isobutane, and propane. The sensor is typically installed in or on the receiver but can be placed in other locations where level indication is required. Its unique measurement principle and robust construction allow it to endure high pressure and low refrigerant temperatures, making it suitable for transcritical CO2 refrigeration systems.
