TCVoltsToTemp() [UD Library]

A utility function to convert thermocouple voltage readings to temperature.

Declaration:

LJ_ERROR _stdcall TCVoltsToTemp ( long TCType,

double TCVolts,

double CJTempK,

double *pTCTempK)

Parameter Description:

Returns: LabJack errorcodes or 0 for no error.
Inputs:

• TCType – A constant that specifies the thermocouple type. Below are the thermocouple type constants and their valid temperature ranges.
  LJ_ttB : 250 to 1820 °C
  LJ_ttE : -200 to 1000 °C
  LJ_ttJ : -210 to 1200 °C
  LJ_ttK : -200 to 1372 °C
  LJ_ttN : -200 to 1300 °C
  LJ_ttR : -50 to 1768 °C
  LJ_ttS : -50 to 1768 °C
  LJ_ttT : -200 to 400 °C

• TCVolts – The thermocouple voltage.

• CJTempK – The temperature of the cold junction in degrees K.

Outputs:

• pTCTempK – Returns the calculated thermocouple temperature in degrees K. If the temperature is outside the valid temperature range for the thermocouple type, the returned temperature value is -9725.85.
