◆ Application
Pors-TR(K) series armored RTD are generally, matching with indicator, recorder, PC, used to measure temperature of liquid, steam, gas and solid’s surface within range of -200℃~ 500℃ in producing process; and can work as sensoring element of the fabricated RTD.
◆ 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
Rapid thermal response, dynamic error reduce;
Little diameter, no limit to length;
High accuracy;
Imported film resistance element used, performance is stable and reliable;
◆ Standard: The sensors are made complying with standard: IEC60751, JB/T8622-1997
◆ Measuring range and Tolerance
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.
