Quick Details

  • Brand Name: Explosion-proof thermal resistance
  • Model Number: Explosion-proof thermal resistance

Specifications

■ Application
Usually matching with display instrument, memorizing meter, electronic computer . Directly measure hydrocarbons which may cause explode 0 ~ 500 ℃ about liquid, steam,gas and  surface temperature of solid medium at the production site .
■ Characteristics
● Pressure spring type temperature sensing element, good vibration resistance performance;
● large measuring range;
● without payment of compensation wire, cost savings;
● imported film resistor, reliable and stable performance
■ Principle
Explosion-proof thermal resistance using gap explosion-proof junction box and other components of the design principles, with sufficient strength, all can produce a spark, arc and dangerous temperature components are sealed in the junction box cavity, when the cavity when the explosion occurred, can pass through the gap of joint surface quenching and cooling, the explosion of flame and the temperature sensor is not to outside of the cavity, thus the temperature.
■ Main technical parameters
Executive standard ● product
IEC751
JB/T86221997
JB/T96231997
JB/T5518-91
■ Cold insulation resistance
Explosion-proof thermal resistance is 15 ~ at ambient temperature of 35 ℃, relative humidity of not more than 80%, the test voltage is 10 ~ 100V (DC) insulation resistance than 100M Ω.M between the electrode and the outer tube
■ Temperature range and tolerance
● temperature range and tolerance
■ Selection guidelines
