Technical data: HBSR-HFC

The HBSR-HFC is a Level Switch designed for detecting common HFC, HFO, and CFC refrigerants in refrigeration systems. It is typically installed in refrigerant vessels, pump separators, economizers, or heat exchangers.

Features:

• Liquid temperature range: Operate across a temperature range of -40°C to 50°C (-40°F to 122°F).
• Pressure tolerance: Rated for pressures up to 100 bar (1450 psi).
• Power supply: The switch operates on a 24V AC/DC power supply.
• Split design: Simplifies installation and diagnostics; electronic parts can be removed with two screws.
• LED indicators: Provides clear visual feedback when refrigerant is detected.
