Fabricated RTD

Fabricated RTD
Product name : Fabricated RTD
Item : Pors-TR
Details :
◆ Summary
     Pors-TR series RTD are generally assembled by temperature sensing element, protective sheath, installtion fixtures and terminal box, matching with indicator, recorder, PC, and generally used to measure temperature of liquid, steam, gas and solid’s surface within range of -200℃ ~ 500℃ in producing process.

◆ Working Principle 
     Resistance of RTD varies with temperature change; this feature is used for RTD to measure temperature. When resistance of the RTD changes, the connected indicator will display the corresponding temperature.

◆ Features
     Press spring fixed temperature sensing element, good vibration-proof performance;
     Compensation wire is no need, cost saved;
     High accuracy
     high mechanical strength, good pressure-proof capacity;
     Imported film resistance element used, performance is stable and reliable;

◆ Standard: The sensors are made complying with standard: IEC60751, JB/T8622-1997, JB/T8623-1997

◆ Measuring range and Tolerance
Model Type Measuring range ℃     class Tolerance
TRP PT100 -200~500 A ±(0.15+0.002|t|)
B ±(0.30+0.005|t|)
TRC Cu50 -50~+100 --- ±(0.30+0.006|t|)
Cu100
Note: t is temperature of the measured medium;

◆ Insulation resistance  (Normal temperature)
     In temperature of 15~35℃, related humidity is not more than 80%, tested voltage is 10~100V (DC), insulation resistance between electrode and external shetath is more than or equal to 1000MΩ.

◆ RTD without installation fixture
