Armored thermal resistance is a kind of temperature sensor, armored heater it is smaller in diameter than the assembled thermal resistance, easy to bend, good shock resistance, easy to use, suitable for installation in the assembled thermal resistance can not be installed occasions, our company produces WZPK series armored thermal resistance with imported thermal resistance temperature measuring elements, therefore, It has the advantages of precision, sensitivity, fast thermal response time, stable quality and long service life.
Armored thermal resistance outer protective sleeve is made of stainless steel and filled with high density oxide material insulator, therefore, armored thermal resistance has strong anti-pollution performance and mechanical strength, suitable for installation in harsh environment.
Armored thermal resistance can be used to measure temperature in the range of -200-600℃. It can be directly connected with copper wire and secondary instrument. Because of its good electrical output characteristics, armored thermal resistance can provide accurate temperature change signal for display instrument, recorder, regulator, scanner, data recorder and computer.
● Working principle
Working principle of armored thermal resistance: under the action of temperature, the resistance of thermal resistance wire changes accordingly, and the display instrument will indicate the temperature value corresponding to the resistance value generated by thermal resistance.
● Main technical indicators
The resistance value (R100) of the thermal resistance sensor at 100℃ and the R0 ratio of its resistance at 0℃ :(R100/R0)
Grading Pt100: Grade A R0=100±0.06 ω
Class B R0 = 100 + 0.12 Ω
R0 / R100 = 1.3850
