Type：assembly thermal resistance
Illustrate：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.
Assembly 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.
Feature
Spring thermal sensor with good shock-proof performance
No compensational wire, spare cost.
High measuring accuracy
High mechanical strength, good pressure-resistant performance
imported film resistor with stable & reliable performance
Operation theory
It is based on that temperature change of material results in charge of its resistance.
When resistance value change, the working instrument will display relevant temperature.
Main technical parameters
Executive standard
IEC751
IB/T8622-1997
JB/T8623-1997
Insulation resistance at normal temperature
The insulation resistance between electrode and protection tube of armored resistance shall be no less than 100M Ω
under condition that environment temperature is 15~35 C, relative humidity is no more than 80%, and testing voltage is D.C.10~100V.
