    Product Details:
    Minimum Order Quantity1 Piece
    Thickness4..20mA
    HBDF is available in 3 variants10m, 20m, and 30m

    Made by HB Products of Denmark .

    HBDF is a simple solution for energy-optimal automatic defrosting of evaporators.

    It results in energy saving, gain more freezing capacity with optimal defrost periods.

    The sensor measures the thickness of ice building up between the fins and sends a 4..20mA or digital ON/OFF signal to the control systems.

    The Defrost sensors are based on capacitive measuring principles, in which an isolated steel wire acts as a conductor and the evaporator fins and tubes act as the second conductor jointly forming viable electrical capacitor.

    Change of the measured signal occurs when ice is build-up between the fins as the sensor is measuring the dielectric difference between air and ice.

    The sensor can be installed in less than one hour, on both new and old evaporators.

    It can be installed when the system is in operation, and therefore, a system shutdown is not necessary. The electronic part is mounted on the evaporator's frame using 2 screws.

    HBDF is available in 3 variants, with a 10m, 20m, and 30m wire respectively.

    After installation, the sensor should be calibrated/configured to the evaporator it is mounted on.

    BrandMetalex
    TypeSensor
    ApplicationUsed in connection with the HBLT-C1 controller for controlling pumps

    Refrigerant Ammonia Wire Sensor (HBLT-wire) is a capacitive sensor for level measurement of Ammonia refrigerant in industrial refrigeration systems. The sensor has an output signal of 4-20 mA, which is proportional with 0 and 100%. Its output signal is 4 mA for an empty container and 20 mA for a full container. HBLT-wire can be adjusted in length to the current application.
    The sensor element consists of a 2 mm steel wire as well as a Teflon tube. Both parts are provided with a length of 4 m and can be shortened with diagonal cutters or other pliers.
