Resolution
The resistance of a sensor at a specific temperature can be downloaded here. The devices covered are Schneider-Electric's range including Andover, TAC and Satchwell and other manufacturers temperature sensors. All are detailed below.
For the standard thermistor, tables click here, where the INET, I/A, and BALCO resistance tables are detailed.
This is the chart for the Precon Thermistors - ACCTemp 10K Type III thermistor also known as the 10K4A1 Thermistor.
For EcoStruxure I/O Module universal inputs, the type of thermistor bead is classed as a: "10k Type I (Continuum)"
Satchwell T range is now known as STR600, STP660, STD600, STO600 10K3A1 with shunt
Drayton DC1000, DC1100 30K6A1 is now known as STR600D, STP600D, STO600D

For I/A Series Controllers (MNL/MNB)
Compatible sensors that have a built-in 11k shunt resistor include the TS-5711-850, TS-57011-850, TS-57031-850, and TSMN-90110-850 Series.
Any sensor that matches resistance to temperature curve for a 10K Thermistor Type G (U.S. Sensor), Type 9 (Dale/Vishay) or Type III (ACI Series AH) can be used with the I/A Series MNL and I/A Series MNB series controllers, provided that a 11k ± 0.1% 1/8 watt resistor is wired in parallel with the sensor. The input has a range of -10 to 135 °F (-23.3 to 57.2 °C) with an accuracy of ±1% of span.
