Ultrasonic transducer for calorimetry

摘要

The invention relates to an ultrasonic transducer having at least two electrodes 2, 3 which include a transducing member 1. According to the invention, one of the electrodes 3 is designed as a temperature measuring shunt having two terminals 3a, 3b. The temperature measuring shunt expediently has a meandering structure in this case. Consequently, the temperature measurement required for the calorimetry can be carried out using the ultrasonic transducer. It is possible to eliminate a special temperature sensor, so that the flow measurement carried out using the ultrasonic transducer produces no disturbance in the flow profile. <IMAGE>
