Convert Thermocouple Reading VI

Owning Palette: Scaling VIs

Requires: Base Development System

Converts a voltage reading from a thermocouple into a temperature value. Wire data to the Voltage Waveform (waveform), Voltage Array (array), or Thermocouple Voltage (scalar) input to determine the polymorphic instance to use or manually select the instance.

Note  This VI does not work with the NI 9211 C Series module. Instead, use the NI 9211 Convert to Temperature VI located in the labview\examples\CompactRIO\Module Specific\NI 9211\NI 9211 Support Files.llb directory.

Use the pull-down menu to select an instance of this VI.

Convert Thermocouple Reading (waveform)

	Temperature Units is the units of temperature the VI outputs. This input accepts the following values. 0 Celsius 1 Fahrenheit 2 Kelvin 3 Rankine
	Voltage Waveform is a waveform of voltages read from a thermocouple.
	ThermocoupleType can be B, E, J, K, R, S, T, or N. This input accepts the following values. Refer to your thermocouple user manual for more information about thermocouple types. 0 B 1 E 2 J 3 K 4 R 5 S 6 T 7 N
	CJC Voltage is the cold-junction compensation reference voltage. The CJC Voltage parameter is either the IC sensor or the thermistor sensor, as specified by CJC Sensor.
	CJC Sensor is the type of cold-junction compensation sensor you are using. A CJC Sensor value of 0 selects the IC sensor. A CJC Sensor value of 1 selects the thermistor sensor.
	Type of Excitation indicates the voltage and current reference. This input accepts the following values. 0 Voltage Reference 1 Current Reference
	Temperature Waveform returns the linearized temperature value in the units specified in Temperature Units.
