TS-3 Temperature Sensor

USA - TS-3 Temperature Sensor

Ultrasonic Level Accessories

The TS-3 temperature sensor provides an input signal for temperature compensation of specific Siemens ultrasonic level controllers. 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 temperature sensor should not be mounted in direct sunlight.

The TS-3 temperature sensor is used in conjunction with ultrasonic transducers that do not have an integral temperature sensor. It is also recommended in 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 temperatures are encountered.


The TS-3 is not compatible with devices using the TS-2 or LTS-1 temperature sensors. Refer to the associated transceiver manual 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).

What precision and reliability mean for your applications

Your facility is a busy place - and materials and conditions inside your tanks/vessels/wells are always changing. Siemens ultrasonics selects the correct echo after every measurement, giving you stable readings while still allowing rapid response to actual changes in the material level. The result? Operations are more cost-effective. Inventory monitoring is always precise. Processes can be better controlled. And expensive spill cleanups can be avoided.
