HBX-DX-R-3-8 HB Products Vapor Quality Control Sensor

HBX-DX 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 to 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'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.  

Product Features:

• Measures vapor quality in refrigeration systems – measures the relationship between gas and liquid (Refrigerant Log Ph diagram).
• A dry suction pipe from the freezer minimises loss of pressure in risers and provides increased flexibility of the pipe installation. 
• The vapor quality sensor allows for the operation of DX ammonia technology with minimal "superheat".
• 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.
