Vapor Quality Sensor (DX systems)

Technical data: HBX-DX

HBX-DX is a new revolutionary, patent-pending sensor technology, and it is thus the first sensor in the world capable of measuring the relationship between vapor 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 HBX-DX measures the dryness of the gas in the range X = 0.85...1.05.
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.

The sensor cannot measure actual overheating, but with proper installation and system design, overheating can be reduced or eliminated, thus leading to substantial energy savings. 

Installation of HBX sensors 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.

Product features

The vapor quality sensor allows for the operation of DX ammonia technology with minimal "superheat".
A dry suction pipe from the freezer minimises loss of pressure in risers and provides increased flexibility of the pipe installation. 
30 to 50 times less refrigerant required (ammonia systems), following the installation of the vapor quality sensor and the construction of the system based on DX technology.
Measures vapor quality in refrigeration systems – measures the relationship between gas and liquid (Refrigerant Log Ph diagram).
