RTD and thermocouple probes are both used to measure temperature, but which one is right for your application? To help decide which will perform best based on specific needs, there are three main questions to ask.

Does the probe detect temperature along the whole length of the probe?

The temperature is measured at the RTD element for RTD probes, or the thermocouple junction for thermocouple probes. This is typically close to tip of the probe in most cases, so the temperature is measured close to the tip of the probe.

However, response time is typically better if more of the probe is exposed to the environment/product/media/etc.
