Temperature compensation is essential in applications where temperature variations of the sound medium are expected. By installing the temperature sensor close to the sound path of the associated ultrasonic
transducer, a signal representative of the sound medium’s ambient temperature is obtained. The tem-
perature sensor should not be mounted in direct sunlight.The TS-3 is used in conjunction with
ultrasonic transducers that do not have an integral temperature sensor. It is also recom-mended in
professional cases where the integral temperature sensor of the transducer cannot be used. The following conditions are typical for use of the TS-3 sensor: where a fast reaction to temperature variations is required, where a flanged ultrasonic transducer is used, or where high tempera-tures are encountered. The TS-3 is not compatible with devices using the TS-2 or LTS-1
temperature sensors. Refer to the associated transceiver man-
ual for more details.•Key Applications: For use in applications where temperature sensor measurement from transducer does not accurately represent vessel temperature. Used for applications requiring quick temperature response (open channel monitoring). >
