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.

Inputs/Outputs

  • cu16.png Temperature Units (C) —

    Temperature Units is the units of temperature the VI outputs.

    This input accepts the following values.

    0Celsius
    1Fahrenheit
    2Kelvin
    3Rankine
  • c1dsgl.png Voltage Array —

    Voltage Array is an array of voltages read from a thermocouple.

  • cu16.png ThermocoupleType —

    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.

    0B
    1E
    2J
    3K
    4R
    5S
    6T
    7N
  • csgl.png CJC Voltage —

    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.

  • cu16.png CJC Sensor(0) —

    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.

  • cu16.png Type of Excitation —

    Type of Excitation indicates the voltage and current reference.

    This input accepts the following values.

    0Voltage Reference
    1Current Reference
  • i1dsgl.png Temperature Array —

    Temperature Array returns the linearized temperature value in the units specified in Temperature Units.
