Infrared Sensor – Based Temperature Control for E.G.O. Induction Cooktop

In this paper, a precise real-time temperature control system based on infrared (IR) thermometry for domestic induction cooking is presented. The system is a part of the MSX E/2 network; the system exists in our patented solution, which is based on two IR sensors with filters and one emissivity measurement optical part. A real product is implemented in an EGO induction cooker with universal LIN interface with aim of testing cooking processes. A proportional-integral controller is applied to establish the output power level and a signal conditioning circuit has been implemented. A simple and necessary calibration procedure with a wireless MSX sensor is presented. Tests and their results are obtained through real cooking processes in range between 60°C and 250°C with a maximum temperature error of 5 °C (including tests for cooking soup, pasta, deep fry, roast etc.).
