Measurement of the temperature transient response of the bimetallic thermometer

Mechanical parts in many field tested sensors are now replaced by electronic equipment. Such electronic equipment is sensitiveto ambient temperature and ambient temperature changes. One example is the bimetallic thermometer used for oil temperature measurement in an automobile oil pan. To replace the bimetallic strip with electronics, the mathematical model of the dynamic behavior of the bimetallic thermometer was constructed. The sensor measures the temperature of oil in automobile oil bath. The task serves as a pilot example for the larger project focused on the study of thermal load of sensors. This paper deals with verification of dynamics of temperature fields in thc bimctallic thcrmometer obtained by mathematical simulation of the sensor by the measurement. The measurement was made by infrared camera FLIR THERMACAM SC2000. The image processing methods will bc used to calculatc the correlation of the measured data with the data calculated from analytical model numerically by the finite element method in the future
