Temperature (°C) to Resistance Charts (ohms).
Upgrading the site BMS, but retaining the existing sensors and the sensor resistance values are not known.
The resistance of a sensor at a specific temperature can be downloaded below, there are a number of tables collated from different sources for a number of Schneider Electric sensors and other BMS suppliers.
In EBO, the thermistor selection in the IO module or controller does not represent the thermistor bead type, an example is the Continuum Type I in EBO, but the bead is a Type 3,. For further information regarding this see the KB article Thermistor type selection in EBO.
The document All Sensors covers the following:
- Satchwell DxT sensors are replaced by STR600, STP660, STD600, STO600 type T with shunt, and use the Satchwell T range chart
- Drayton DC1000, DC1100 30K6A1 is now known as STR600D, STP600D, STO600D
- Andover 10K4A1
- TAC Inc. Vista 1.8KA1
- I/A series 10K3A1 with 11K shunt
- INET 10K2A1 (10k Dale)
- BALCO 1000 ohm RTD
Older Satchwell ranges:
- Satchwell DW1204, DW1305, DWS1202
- Satchwell DO
- Satchwell DD/DR
Other manufacturers included:
- Allerton 3K3A1

Further information for the Continuum ACC Temp 10K Type 3 also known as 10K4A1, the document Thermistor Temp Resist Chart (Precon Thermistors) is available.
For I/A Series Controllers (MNL/MNB)
Compatible sensors that have a built-in 11k shunt resistor include the
- 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.
