4. Functionality
The MDTEK3705 operates on the thermoelectric principle, generating a voltage proportional to the temperature difference between its measuring (hot) junction and reference (cold) junction. The Type K thermocouple is one of the most widely used sensor types due to its broad temperature range, durability, and cost-effectiveness.
