THERMOCOUPLE APPLICATION ADAPTOR FOR EMANT300

The Thermocouple Application Adaptor allows users to connect thermocouples to the EMANT300 Low Cost USB Data Acquisition Module without soldering or breadboarding. It is ideal for use in hands-on teaching laboratories and projects that require temperature measurements.

Comes with example programs in LabVIEW and .NET C# and Visual Basic.

FEATURES

  • Accepts up to 2 thermocouples
  • Types J,K,T,E, R,S,B Thermocouples
  • Onboard Cold Junction Compensation
  • Accepts Thermistors, RTDs

Thermocouples produce an output voltage which depends on the temperature difference between the junctions of two dissimilar metal wires. It is important to appreciate that thermocouples measure the temperature difference between two points, not absolute temperature.

In our example, we measure one of the junctions the cold junction temperature using a thermistor, whilst the other end is attached to a probe. We will use the Type K Thermocouple. The positive conductor is made of Chromel, and the negative conductor is made of Alumel.

The NIST ITS-90 Thermocouple Database gives temperature -- electromotive force (emf) reference functions and tables for the letter-designated thermocouple types B, E, J, K, N, R, S and T. These reference functions have been adopted as standards by the American Society for Testing and Materials (ASTM) and the International Electrotechnical Commission (IEC).

K Type Thermocouple

Together with the thermocouple application adaptor and EMANT300, it forms a thermocouple training kit. This K type thermocouple is only suitable for temperatures up to 150o C as the tip is soldered and not welded.

While stock lasts, every order of the Thermocouple Application Adaptor comes with one K Type Thermocouple at no additional charge
