IntroductionRTD, also Resistance Temperature Detector,or resistive thermal devices, thermal resistance temperature measurement. 2. PrincipleThe principle is based on the resistance value of a conductor or semiconductor as the temperature changes and changes in the characteristics. 3. TypesCommonly used industrial heat resistance Pt100, Pt1000, Cu50, Cu100.Platinum RTD temperature measurement range is typically 200-800 degrees Celsius below zero, the thermal resistance of copper minus 40-140 degrees Celsius.4.Advantages:You can also remote electrical signal, high sensitivity, stability, interchangeability and accuracy are better. RTD do not need connection wire, and cheaper than thermocouple.3. Response Time: Response time is the sensors ability to react to temperature changes in the process. The ability to track process changes depends on the sensors thermal mass and proximity to the process. Direct immersion sensors generally are the fastest responding, but in many applications a thermowell is used so that the process does not have to be drained to change a sensor.5ParametersTypeTemp RangeRTD SensorPT100PT1000CU50-200~+650C-200~+650C-200~+650CPairs of Sensor WireSimplexDuplexMounting & Fixing1:without fixing device2:fixed thread3: movable flange4: fixed flange5: right-angle movable flange6:fixed thread in wimble shape protection tubeConnection Boxwater-proofSensor End1: variable section2: sheathed elements3: flexible sheathed elements7.
