The RTD Series Precision RTD (Resistance Temperature Detector) Simulator provides a very broad-range of absolute resistance values that replace RTD’s,thermocouples. Thermocouples present a re-sistance that depends on the temperature. The RTD simulator effectively replaces an RTD to test, analy

The previous equations define the RTD resistance as a function of its temperature, R. RTD (t). However, to implement an RTD sensor interfacing circuit, the RTD temperature must be deter-mined, instead, as a function of its resistance, T. RTD (r). This may be less straightforward, given the

Table 2 lists the coefficients used in this equation for each of the TCR values that the [c]FP-RTD-124 supports. If you have a nonstandard RTD that does not match one of these linearization curves, measure the resistance with the [c]FP-RTD-124 and convert the resistance to temperature in the manner suggested by t

So at 0 C the resistance is 100 ohms, at 100 C resistance 138.5 ohms. JIS standard platinum has a temperature coefficient, or (α) value, of 0.003916 ohms/ohms/ C. So a 100 ohm platinum RTD will increase in resistance by 0.3916 ohms for every 1 C of temperature in-crease. So at 0 C the resistance is 100 ohms, at 100 C resistance 139. .

4-wire RTD and ohms T/Cs and millivolts RTD with compensation loop (2) (1) Emerson provides 4-wire sensors for all single-element RTDs. You can use these RTDs in 3-wire configurations by leaving the unneeded leads disconnected and insulated with electrical tape. (2) Transmitter must be configured for a 3-wire RTD in order to recognize an RTD with a

RTD sensor elements are constructed from pure mate-rials that have their resistance at various temperatures documented. In other words, the material has a predic-table change in resistance as the temperature varies. It is this change that is used to determine the actual tempera-ture. RTD

the Resistance Temperature Detector (RTD), its construction, and how it operates. We saw that choosing one RTD type over another gave consideration to its physical construction, sensitivity, material and insulation, and temperature range. We also looked at the RTD Temperature Coefficient of Resistance (TCR)

RTD THEORY Page 3 2-wire construction is the least accurate of the 3 types since there is no way of eliminating the lead wire resistance from the sensor measurement. 2-wire RTD’s are mostly used with
