Rod Style - Vapor Quality Sensor

Technical data: HBX-DX-R & HBX-CR-R

The rod style sensor has been a reliable choice for several years, providing consistent performance when installed correctly. Unlike other sensor types, this sensor measures the liquid inside the sensor element itself, not between the inner element and the pipe walls.

It is important to note that this design requires specific installation; it must be placed where the liquid flows at the bottom of a horizontal pipe, typically in an elbow with the sensor element at the lowest point.

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 50 mm to 200 mm.
  • Sensors for all types of liquids: Works with a wide range of 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.
