Description
â—†
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 ***0℃ ~ **0℃
in producing process.
â—† Working
PrincipleÂ
    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.
â—† 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;
â—† Standard: The
sensors are made complying with standard: IEC****1, JB/T********7,
JB/T********7
