Inline Housing - Vapor Quality Sensor

Technical data: HBX-DX-IN / HBX-CR-IN 

The Inline Vapor Quality Sensor is designed to measure the flow of refrigeration systems efficiently and flexibly. Available in a straight configuration, it comes in sizes from 25 mm to 65 mm and accepts flow in both directions. Thanks to its smooth internal design, this sensor offers minimal pressure loss, making it a highly efficient option. It can be installed in either horizontal or vertical positions, providing versatility in various setups.

Key features

  • LED indicators: Provides clear visual indicators for power supply and alarm status.
  • Flexible system compatibility: Works with both DX systems and overfeed systems.
  • Pipe sizes: Available in pipe sizes ranging from 25 mm to 65 mm.
  • Sensors for all types of liquids: Suitable for all common liquids.
  • Split design: Simplifies installation and diagnostics; electronic parts can be removed with two screws.
  • Easy configuration: Configuration with a PC using HB Tool software.
