Temperature is the most commonly measured of all physical parameters.

The dataTaker data loggers support all of the commonly used temperature sensors including thermocouples, RTDs, solid state or integrated circuit (IC) temperature sensors and thermistors.

Thermocouple types B, C, D, E, G, J, K, N, R, S and T

The choice of temperature sensor is determined by a number of factors, including the temperature measurement range, degree of accuracy needed, operating environment, and cost.

For each of these different types of temperature sensors the dataTaker performs all of the necessary compensation and linearization calculations.

Units of Temperature

The units of temperature measurement by the dataTaker may be degrees Celsius, Fahrenheit, Kelvin or Rankine.

The units of temperature required are selected by the Parameter36 command (See Section III - Parameter Commands).

The permitted settings for Parameter36 and the unit of temperature that each represents are listed below

P36=0         Degrees Celsius     (Default)
P36=1         Degrees Fahrenheit
P36=2         Degrees Kelvin
P36=3         Degrees Rankine

Using DeTransfer, the units of temperature are set by the command for example

which in this case defines the units of temperature as Degrees Fahrenheit.

Using DeLogger, the units of temperature can be set in the Program Builder. Click on the Settings tab, click on the Set Temperature button, and select the temperature units you require in the dialog which opens.

 

 

This selection is not transferred to the dataTaker until the next time that a program is sent to the logger. If you need to change the temperature units in the logger without sending a new program (therefore replacing the program already in the logger), then the Parameter36 commands can be sent directly from the Text View.
