Pt100 increases its resistance as heat is applied. Read analog input as voltage. 4 bytes for a floating point object.

1000 ohm at 0c item2. A lookup table is a convenient way to convert a thermistors adc reading to temperature. As an example assume t1 in the circuit above to be part number ntcle413e2103h400 from vishaydale inc.

For example the resistance of a pt100 at 126c is 14832 ohms. Click here to download all of these tables. 44 029 20 734 040.

These temperature tables provide cross reference information for specific types of thermocouples and rtds at various temperatures both fahrenheit and celsius. To get celsius degree readings we must. The pt100 resistance lookup table uses unsigned 16 bit integers because.

Arduino can read voltage on analog input. Temperatures in multiples of ten can be found down the left axis whilst for more precise readings you must move along the horizontal axis between one and nine. This thermistor has the resistive characteristics shown in the table below.

44 029 20 734121 fax. Unsigned integers require 2 bytes vs. 100 ohm at 0c pt 500.

Resistance characteristic is described in pt100 resistance table. The table below can be used as a referencing tool to find the relationship between a range of temperatures and resistance for pt100 rtd sensors.
