TS-3 temperature sensor
TS-3 temperature sensor
1
Overview
The TS-3 temperature sensor provides an input signal for temperat
ure compensation of specific Siemens ultrasonic level controllers.
Benefits
•
Chemically resistant ETFE enclosure
•
Fast response time
•
Approved for use in potentially explosive atmospheres
Application
Temperature compensation is essential in applications where tem
perature 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 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 can
not 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 controller manual for
more details.
•
Key Applications: for use in applications where temperature
sensor measurement from transducer does not accurately repres
ent vessel temperature. Used for applications requiring quick tem
perature response (open channel monitoring).
