datatype_icon

type of excitation

The voltage and current reference.

Name Value Description
Voltage Reference 0 Specifies using a voltage reference.

Use the voltage reference and R1 inputs only with this option.

Current Reference 1 Specifies using a current reference.

Use the excitation current input only with this option.

Default: Voltage Reference

datatype_icon

voltage

The voltage read from a thermistor.

This input supports waveform and double-precision, floating-point data types.

datatype_icon

voltage reference

The reference you apply across a resistor of known value in series with your thermistor. Use this input only when you set type of excitation to Voltage Reference.

Default: 2.5 V

datatype_icon

R1

The value of the resistor in series with your thermistor expressed in ohms. Use this input only when you set type of excitation to Voltage Reference.

Default: 5000 Ω

datatype_icon

excitation current

The excitation current applied to the thermistor. Use this input only when you set type of excitation to Current Reference.

Default: 100 µA

datatype_icon

temperature units

The units of temperature this node outputs.

Name Value Description
Celsius 0 Returns temperature values in Celsius.
Fahrenheit 1 Returns temperature values in Fahrenheit.
Kelvin 2 Returns temperature values in Kelvin.
Rankine 3 Returns temperature values in Rankine.

Default: Celsius

datatype_icon

temperature

The temperature value in the units specified in temperature units.

This output returns a waveform or double-precision, floating-point data type depending on the data type of the voltage input.
