Frequently Asked Questions

Q: What is an RTD?

A: An RTD (Resistance Temperature Detector) is a sensor whose resistance changes as its temperature changes.  The resistance increases as the temperature of the sensor increases.  The resistance versus temperature relationship is well known and is repeatable over time. 

An RTD is a passive device.  It does not produce an output on its own.  External electronic devices are used to measure the resistance of the sensor by passing a small electrical current through the sensor to generate a voltage.

Q: Why are there different types of alpha curves for platinum RTD element? 

A: Different agencies or organizations (i.e. governmental, industrial and trade) have defined curves in an effort to develop a standard by which all manufacturers can operate. Some were developed by individual manufacturers based on their own abilities to offer a reproducible curve.
