Armored thermal resistance main technical indicators released time: 2019 - 03 - 14 reading times: zero

Thermal resistance 100 ℃ when the resistance of thermal element ( R100中) And it is in 0 ℃ when the resistance ratio (R0 R100中/ R0) A grade dividing Pt100: R0 = 100 + 0. 06 Ω B R0 = 100 + 0. 12Ωr0 / R100中= 1。 3850 armoured thermal resistor is a kind of temperature sensor, it is smaller than the diameter of a prefabricated thermal resistance, flexible, good vibration resistance, suitable for installation in the case of prefabricated thermal resistance can't install, I WZPK series armored thermal resistance is introduced from thermal resistance temperature measurement component, therefore, is accurate, sensitive, fast thermal response time, stable quality, long service life, etc. Armored thermal resistance cases have stainless steel, with high density in oxidation material insulation, therefore, armored thermal resistance strong pollution resistance and mechanical strength, suitable for installation in harsh environment. Armored thermal resistance can be used to measure - 200 - 600 ℃ temperature range, can be connected directly with copper wires and secondary instrument use, due to the armoring thermal resistance has good electrical output characteristic, can be adjusted to display instrument, recorder, instrument, scanner, data recorder to provide accurate temperature signal and a computer. Integration of explosion protection work integration of the thermal resistance heat resistance profile integrated explosion-proof heat resistance and often display meter, recording meter, electronic computer, such as 4 ~ 20 ma output. Direct measurement within the scope of the 0 ~ 1800 ℃ in the process of producing all kinds of liquid, steam and gas medium, as well as solid surface temperature. Main characteristics of the two wire output 4 ~ 20 ma, strong anti-interference ability; Save the compensation conductor and temperature transmitter installation cost; Measuring range is large; The cold end temperature automatic compensation, nonlinear correction circuit. Working principle of the integration of explosion-proof heat resistance by using the theory of gap flame-proof, when an explosion cavity, can remove from heat and cooling by joint clearance, make after the explosion flame temperature less than outside the cavity, thereby for temperature measurement. Thermocouple ( Resistance) Production of thermoelectric potential ( Resistance) Unbalanced signals are generated from the bridge of temperature transmitter, after amplification into 4 ~ 20 ma dc signal to the instrument, the instrument will show the corresponding temperature value.
