Measurement of thermoelectric voltage of semiconductor - used esp. to determine temperature coefficient of semiconductor temperature sensor

摘要

The semiconductor temperature sensor is touched by two different materials and the thermoelectric voltage lying between the points of contact is measured. The contacts between which the thermoelectric voltage is measured can be a measuring holder in which the temperature sensor is inserted. The contacts of different materials can be lined with a layer of abrasion-proof material. The contacts of the temperature sensor are themselves made of different material. Besides the thermoelectric voltage, the resistance of the temperature sensor is measured and the temperature coefficient is determined from the two measured values.
