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.Continue reading RTD vs. Thermocouple

Can I use a Thermocouple Simulator to calibrate my thermocouple based data logger?
Thermocouple calibrators do not work reliably with most MadgeTech thermocouple loggers. The data logger will pull down the voltage of the thermocouple calibrator enough to alter the reading. While the thermocouple calibrator will recover quickly, the data logger will take the reading before the calibrator has corrected itself. This will lead to an inaccurate reading. Due to this, using a thermocouple simulator is not recommended when calibrating MadgeTech loggers.
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.
