Temperature Sensor TS-2
The TS-2 Temperature Sensor provides a current-source input for corresponding temperature compensation circuitry of the Open Channel Monitor, OCM III. Temperature compensation is essential in applications where variation in temperature of the sound medium is expected.
By installing the temperature sensor in close proximity to the sound path of the ultrasonic transducer, a signal representative of the sound medium's ambient temperature is obtained. The sensor should not be mounted in direct sunlight.
The TS-2 is used in conjunction with ultrasonic transducers that do not have an integral temperature sensor.
It inlcudes a passive circuit that varies its resistance linearly with temperature.
The TS-2 is not compatible with products using the TS-3 or LTS-1 temperature sensors. Refer to the associated transceiver manual for usage compatibility.
