PT100 Platinum Resistor temperature probe 2 wires

Hot response time

The thermal response time is when the output variable value of the thermal resistance is equivalent to 50 % of the step change under the action of the order temperature, the time required is represented by τ 0.5.
Reference value of thermal resistance heat response time
Diameter (mm) φ3 φ4 φ5 φ6 φ8)0.5 (second) ≤3 ≤5 ≤8 ≤12 ≤18

Note:
When the armor component and the external protective tube form the armor thermal resistance machine, because the diameter and wall thickness of the protective tube is far greater than the armor cover, the heat response time mainly depends on the dynamic response of the protective tube.

N room temperature insulation resistance
The thermal resistance at the ambient temperature is 15-35 ° C, the relative humidity is not greater than 80%, and the test voltage is 10-100V (DC) electrode and the insulation resistance between the coat.

Protective pipe material is generally 1CR18NI9TI 0CR18NI12MO2TI
