Resistance Temperature Detectors - RTD's
Microdaq.com offers several types of RTD's. An RTD or Resistance Temperature Detector is simply
a sensor that senses temperature by measuring the change
in resistance of metal wires. Using an RTD is a highly
accurate way of measuring temperature.
Tip Sensitive Industrial RTD's
The sensing tip of these probes is constructed of copper
alloy, twenty times more conductive than stainless steel. Sensors react
more quickly to changes and indicate tip temperature instead of stem
temperature.

Notes
- The accuracy specifications are for the
probes only, and must be added to the logger’s accuracy to determine
the combined measurement accuracy.
- Accuracy on RTD's are stated as the
deviation from what is the standard resistance for an RTD at a
certain temperature.
