The JUMO CALC application allows different calculations for thermocouples according to EN 60584, platinum - RTD temperature probe according to DIN EN 60751 and transmitter.

Thermocouple – calculations

The cold junctions. Temperature can be individually specified. Out of a specified thermoelectric voltage the associated temperature can be calculated. Or vice versa, out of a temperature value the associated thermoelectric voltage can be calculated. In addition, the standardized tolerance classes can be selected according to DIN IEC 60584. For each respective measuring temperature the admissible tolerance as well as the lower and upper limit of the temperature and thermoelectric voltage are displayed. The following thermocouple types are available:

•	Precious metal – thermocouples: R, S, and B

•	Non-precious metal – thermocouples: K, N, E, J, and T 

Platinum - RTD temperature probe according to DIN EN 60751

After selecting the nominal value Pt100, Pt500, or Pt1000 the user can calculate the associated resistance value from the specified temperature and vice versa.

After having chosen the tolerance class AA, A, B, and C the calculation of the admissible tolerance follows, the lower and upper limit of the class as resistance and temperature value to the specified temperature.

For the 2-wire circuit: after selecting a specific conducting material (copper, silver, nickel, and iron) the connecting cable and inputs of the conductor cross sections or diameter and the cable length of the lead wire resistance and the associated systematic temperature error for the entered measuring temperature are calculated.

Transmitter – linearization

Transmitters are used to depict the measuring range of a dimension to a standard signal in a linear fashion.

Different temperature ranges (that can also be individually adjusted) and the standard signals (4 mA to 20 mA, 0 V to 10 V) can be selected.

Subsequently the associated output signal can be calculated out of a temperature value or vice versa.
