    Product Details
    WZP-430, 431 Fixed flange Thermal Resistance
    Thermal resistance is measured by applying the principle that the resistance of the metal itself changes when the temperature changes. According to its protective tube structure, it is divided into assembly type(detachable) and armor type(non-detachable, packed platinum resistance). At present, there are two major types of installed thermal resistors used in the field: platinum thermal resistors with a fraction number of Pt100 and copper thermal resistors with a fraction number of Cu50.



    Industrial WZ series assembly thermal resistors can be used directly with secondary instruments. The temperature of liquid, steam and gas media and solid surfaces in various production processes can be measured from -200 °C to 420 °C.
    Due to its good electrical output characteristics, it can provide accurate temperature change signals for display instruments, recorders, regulators, scanners, data recorders, and computers.

     


    Structure of the Assembly Thermal Resistance
    Assembly heat resistance mainly consists of junction box, protective tube, connection terminal, insulation sleeve and temperature sensing element.

    Nominal pressure
    Generally refers to the static external pressure that the protective tube can withstand without breaking at the working temperature. In fact, the allowable working pressure is not only related to the protective tube material, diameter, wall thickness, but also to its structure, installation method, depth of placement, and the velocity and type of medium to be measured.

    Lmin-- minimum available insertion depth (mm)

    Ln-- length of temperature sensing element (mm)
