Armored thermal resistance is a kind of temperature sensor, it is smaller than the assembled thermal resistance diameter, easy to be bent, good shock resistance, suitable for installation in the assembled thermal resistance can not be installed on the occasion, our company's production of WZPK series armored thermal resistance using the introduction of thermal resistance temperature measuring element, therefore, has the advantages of accurate, sensitive, rapid thermal response time, stable quality, long service life.

Armored thermal resistance outer protective sleeve is made of stainless steel, full of high density oxidizing 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 the temperature in the range of -200-600℃, can be directly connected with copper wire and secondary instrument use, because armored thermal resistance has good electrical output characteristics, can provide accurate temperature change signal for display instrument, recorder, regulator, scanner, data recorder and computer.

● Working principle

Armored thermal resistance working principle: under the action of temperature, the resistance of the thermal resistance wire changes with it, and the display instrument will indicate the corresponding temperature value of the resistance value generated by the thermal resistance.

● Main technical indicators

Ratio of resistance value (R100) of thermal resistance sensing element at 100℃ to resistance R0 at 0℃ : (R100/R0)

Grading Pt100: Grade A R0=100±0.06Ω

Grade B R0=100±0.12Ω

R0 / R100 = 1.3850
