HBX-OVC

HBX-OVC - HBX Vapor Quality Sensor Flooded systems)

HBX-OVC is thus the first sensor in the world capable of measuring the relationship between gas and liquid a refrigeration system. The sensor measures the degree of dryness, “X”, of the gas in the gas pipes, and the value is converted into a 4-20 mA analogue signal corresponding to “X”. The measuring range for HBOVC is X = 0.6...0.9.

The sensor is available in two variants, "Rod Style” for installation in a pipe elbow and “In-line” for welding into the suction pipe.

The sensor offers very precise measurements and provides instant read-outs of the gas quality, making it useable in most evaporators (plate, pipe, and air evaporators). 

 

      

 

The sensor’s microprocessor also functions as a controller, enabling the direct control of a modulating motor valve, thereby bypassing the external controller or the PLC. The controller can be set up with all the parameters that are necessary for regulating a modulating motor valve or a stepper motor valve. The sensor is available with a cable for direct supply to and control of the motor valve, or as a sensor where the signal is sent to the external controller/PLC.

  • Can also be used in HFC refrigeration systems.
  • Measures vapor quality in ammonia refrigeration systems – measures the relationship between gas and liquid (Refrigerant Log Ph diagram).

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.

Installation of HBX rod style in strainer/filter houses
For proper functionality of X-sensor it is vital with correct installation. This has proven to be challenging when welded in to bends. We are therefore ready with a new solution with integration in strainer houses mounted at the suction line. The function is as on the inline sensor but the advantage is that the filter lid and sensor element can be removed and cleaned if necessary.
