Page 3: Function And System Design
These resistance thermometers use a Pt100 temperature sensor according to IEC 60751. The temperature sensor is a temperature-sensitive platinum resistor with a resistance of 100 Ω at 0 °C (32 °F) and a temperature coefficient α = 0.003851 °C Endress+Hauser... -
Page 4: Measuring System
IEC 60751 can only be observed with TF sensors at temperatures up to approx. 300 °C (572 °F). Measuring system Endress+Hauser offers a complete portfolio of optimized components for the temperature measuring point – everything you need for the seamless integration of the measuring point into the overall facility. -

Page 11: Overvoltage Protection
Overvoltage protection To protect against overvoltage in the power supply and signal/communication cables for the thermometer electronics, Endress+Hauser offers the HAW562 surge arrester for DIN rail mounting and the HAW569 for field housing installation. For more information see the Technical Information ' H AW562 Surge arrester' TI01012K and ' H AW569 Surge arrester' TI01013K. -
Page 12: Influence Of Ambient Temperature
In addition to the measurement current, the size of the measurement error is also affected by the temperature conductivity and flow velocity of the process. This self- heating error is negligible when an Endress+Hauser iTEMP temperature transmitter (very small measurement current) is connected. -
Page 13: Calibration
Endress+Hauser offers this kind of sensor-transmitter matching as a separate service. Furthermore, the sensor-specific polynomial coefficients of platinum resistance thermometers are always provided on every Endress+Hauser calibration certificate where possible, e.g. at least three calibration points, so that users themselves can also appropriately configure suitable temperature transmitters. - Page 14 If this is not possible for the calibration, it is advisable to use a connector. → 28 Advantages of iTHERM QuickNeck: • Considerable time savings when recalibrating the device (up to 20 minutes per measuring point) • Wiring mistakes avoided when re-installing • Minimum plant downtime, thereby saving costs Endress+Hauser...
