An overview of industrial thermal resistance thermal resistance as the temperature gauge and automatic temperature control of a temperature sensing element can be directly displayed with the display and recording instrument and supporting the use of instruments or temperature transmitter can also provide a signal to the host computer to the side volume -200 degrees - +500 degrees within the range of liquid, vapor and solid surface body temperature of the medium. Two categories Product Name Model No. indexing measurement range (℃) Industrial platinum resistance WZP Pt10Pt100 BA1 BA2 -200 ~ 500 ℃ industrial thermal resistance of copper WZC Cu50 Cu100 G53 -50 ~ 150 ℃ three basic technical characteristics of tolerance: WZP platinum heat A resistor allows ± (0.15 +0.002 | t |) ℃ B allows ± (0.30 +0.005 | t |) ℃ WZC copper heat resistance allows ± (0.15 +0.002 | t |) ℃ Insulation resistance: When the ambient temperature is 15 -35 ℃, relative humidity less than 80% when the insulation resistance between the warm feeling of documents and the protection tube is not less than 100MΩ. Thermoelectric effect: according to the method prescribed time change caused by platinum RTD depth between the electromotive force measured at the output of not more than 20uV self-heating effects: the excitation power is 5mA (for Pt100) temperature increments of not more than 0.3 ℃ four types of structural features and specifications form the junction box in the form of fixed protection tube diameter (mm) no fixed safety device is fixed at right angles to the threaded mounting flange flanges flanges splash waterproof Φ16 Φ12 Φ8 Code 12345230 12 protection tube material: stainless steel 20 # 1Cγ18Ni9Ti protection tube length (mm) :225-2000, such as: WZC120 copper thermal resistance, mounting no fixed way, splash protection tube diameter 16
