Type：armored thermal resistance
Illustrate：The insulation resistance between electrode and protection tube of armored thermal resistance shall be no less than 100MΩ under condition that environment temperature 15-35℃ ,relative humidity is no more than 80% ,and testing voltage is D.C. 10-100V.
Armored Thermal Resistance
It is usually connected with display meter ,recording meter and computer, etc . to directly measure temperature of liquid ,vapor,
gas and solid surface ranging from -200℃ to 500℃ during various production process .
Features
1, With quick thermal response , reducing dynamic error
2, Small diameter , no limit length
3, High measuring accuracy
4, Imported film resistor with high reliability and stability
Operation Theory
It is based on that temperature change of material results in change of its resistance .When resistance value changes .
the working instrument will display relevant temperature .
