Strainer Housing - Vapor Quality Sensor

Technical data: HBX-ST-DX & HBX-CR-ST

With the sensor integrated into a standard strainer house, installation is straightforward, and functionality is enhanced. The butt-welded connection allows for seamless welding with the same size piping, simplifying the setup process. This design provides not only easy installation but also simple maintenance. The strainer's lid can be removed, allowing you to access the sensor conductor for cleaning when needed.

It's important to note that the flow direction for the Vapor Quality Sensor is opposite to the typical flow direction when used as a strainer. Incorrect installation can lead to functionality issues, so ensure proper alignment for optimal performance.

Key features

  • LED indicators: Provides clear visual indicators for power supply and alarm status.
  • Material options: The sensor integrated into a standard strainer house is available in both carbon steel (DN20 to DN300) and stainless steel (DN20 to DN65).
  • Flexible system compatibility: Works with both DX systems and overfeed systems.
  • Pipe sizes: Available in pipe sizes ranging from 20 mm to 300 mm.
  • Sensors for all types of liquids: Works with a wide range of liquids but is not suited for CO2, propane and butane used in DX applications.
  • Split design: Simplifies installation and diagnostics; electronic parts can be removed with two screws.
  • Easy configuration: Configuration with a PC using HB Tool software.

Product features

Measures the volumetric concentration of gas in a gas/liquid mixture
Balanced evaporator control to achieve semi-flooded operation with high heat transfer
Able to control an expansion valve directly with simultaneously analog 4-20mA output to a PLC
Can be used to optimize and control both DX systems and overfeed systems
Instant measurement and analog output
Split design which makes it easy to install and perform diagnostics on.
Can be used for all common refrigerants

Applications

Flooded system:

HBX ST flooded applikationstegning

Optimum efficiency at all loads is obtain by measuring the Vapor Quality in the outlet of the evaporator and use the signal to change the height of the driving head as shown, lower level will minimize the liquid amount  in the evaporator and secure balanced and dynamic evaporation  during part load and thus optimum heat transfer.

The HBX-OVC-ST Vapor Quality control signal (cable out, 4-20mA) is connected to DI 3 (pin 3) on the HBSLC liquid level sensor and used to change the desired set value for the liquid level in the recirculation vessel/separator.
