The circuit in Figure 1 generates acurrent source that is ratiometric tothe voltage reference. The ADC usesthe same voltage reference to provide aratiometric digital output. Over temperature,the ADC ...

Therefore, a 4-wire configuration results in the best performance. RTD Configuration Circuit A high precision and accurate RTD sensor measurement requires precise signal conditioning, ...

RTD sensors are available using two-, three-, and four-wire configurations, which differ in their use of sense wires (Fig. 1a, 1b, and 1c, respectively).

It also cuts the number of RTD array connections (feedthroughs) from 4N to 4 + N. For 28 sensors, the resulting savings are 2N − 2 − N = 26 inputs and 4N − 4 − N = 80 feedthroughs.

The fine platinum wire used to wind the sensor has a characteristic diameter of 15 to 35 µm and is quite delicate. A damaged or broken RTD sensor wire may result in: Noisy signals An open circuit ...

Keep in mind that no one temperaturesensor is right for all applications.The thermocouple has an unrivaledtemperature range, and the RTD sensorhas excellent linearity. Table 1 summarizes the main ...
