RTD Data Loggers for Any Application
We have several models of RTD Data Loggers that are suitable for use with Resistance Temperature Detector (RTD)’s. RTD sensors provide improved temperature measurement accuracy over thermocouples. The main tradeoff is that they have a more limited temperature measurement range than thermocouples. An RTD Data Logger works by changing resistance in a very predictable way in a proportion to changes in temperature. To make the measurement, these RTD Data Loggers will source a known current or through the RTD and measure the voltage across it. From this it can calculate the resistance and then convert the resistance to temperature. Because the lead wires which attach the sensor to the data logger can cause measurement errors due to their internal resistance, 3 or 4 wire RTD’s can be used which allow the data logger to compensate for the effects of this resistance.
