Vapour quality sensor
HB Products HBDX is a new revolutionary, patent-pending sensor technology, and it is the first sensor in the world capable of measuring the relationship between gas and liquid in 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 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.
