A CALIBRATION SYSTEM FOR SURFACE TEMPERATURE SENSORS
Lucia Rosso, Vito Fernicola · Sensors and Microsystems · 2008
The calibration of contact surface temperature probes greatly depends on the interaction between the sensor and the reference measurement surface. A dedicated calibration system for such probes has been developed at IMGC. It enables the calibration on a temperature-controlled reference surface in the temperature range from ambient to 350°C. The paper describes the prototype, its main metrological features as well as the thermal-fluid-dynamic model of the system for simulating the impact of the various influence parameters on the measurement. The preliminary results of the comparison between the numerical predictions and the experimental values, as obtained from the metrological characterisation of the system, are also reported.
