Armored thermal resistance is a temperature sensor, it is smaller than the diameter of Assembly thermal resistance, easy bending, shock resistance, suitable for installation in the assembly can not be installed thermal resistance of the occasion, I produced WZPK Series Armored thermal resistance with the introduction RTD temperature element, therefore, precise, sensitive, fast thermal response time, stable quality, long life and other advantages.
Armored thermal resistance of the outer protective sheath mining stainless steel, filled with high-density oxide insulator material, therefore, armored with strong anti-pollution thermal resistance and mechanical strength, suitable for installation in harsh environment applications.
Armored thermal resistance can be used to measure the range of -200-600 ℃ temperature, can be directly used copper wire and the second instrument connection, because the armor thermal resistance with good electrical output characteristics, for display instrument, recorder, regulator , scanners, data loggers and computer to provide accurate temperature change signal.
• working principle
Armored thermal resistance works: at a temperature of action, along with the thermal resistance wire resistance change, display meter will indicate the resistance value of thermal resistance generated by the corresponding temperature value.
• Main Specifications
Thermal resistance temperature sensing element resistance 100 ℃, the (R100) and its resistance at 0 ℃ R0 ratio of: (R100 / R0)
Indexing number Pt100: A grade R0 = 100 ± 0.06Ω
