PT100 Temperature Sensor
Price: Unavailable
 
 
1. Fundamentals

Thermal resistance is the use of material changes in temperature itself also changes with the resistance characteristics to measure the temperature. The heated portion of the thermal resistance (temperature sensing element) is a thin metal wire uniformly wound on the double skeleton made of insulating material, when measured medium in the presence of a temperature gradient, the measured temperature range where the temperature sensing element the average temperature in the dielectric layer.

2. The main technical parameters

Name platinum resistance
Indexing number Pt100
Temperature range -5 ~ 170 ℃
Tolerance class A ± (0.15 + 0.002|t|) ℃
    Grade B ± (0.30 + 0.005|t|) ℃
3. Thermal response time

Thermal response time is under the effect of temperature step, the output changes when the thermal resistance value is equivalent to 50% of a step change in the time required by τ0.5 to represent.

Thermal resistance thermal response time reference
Diameter (mm) Φ3 Φ4 Φ5 Φ6 Φ8
τ0.5 (s) ≤3 ≤5 ≤8 ≤12 ≤18
NOTE: When the armored element and outer protective tubes sheathed armored thermal resistance of the whole, since the protective tube diameter and wall thickness is much larger than the sheath, so the thermal response time depends on the dynamic response of the protective tube
4. Insulation resistance at room temperature

100MΩ "">Thermal resistance at an ambient temperature of 15-35 ° C, relative humidity less than 80%, the test voltage is 10-100V (DC) Insulation resistance between the electrode and the jacket pipe> 100MΩ
Insulation resistance:
        Room temperature ≥2000MΩ
        High temperature (500 ℃) ≥300MΩ
Configuration type measuring terminal

5. Protection tube material

    Generally 1Cr18Ni9Ti 0Cr18Ni12Mo2Ti
6. Product performance standards
