What is and what is used for
The sensor in question makes use of the ultrasonic measurement principle, and is therefore based on the analysis of the time elapsing between sending and receiving the ultrasound or on the control of receiving the sent signal. The emitter and receiver are positioned in the same housing. Benefit: it is possible to safely read also non-reflecting or poorly reflecting objects.
Construction
The ultrasonic sensors can detect, with millimetric precision, objects made in different materials, regardless of their shape and colour. The sensor, managed by a microprocessor, bases its operation on an ultrasonic transducer that sends a pulse to the surface whose distance is to be measured, and then reads the resulting reflected echo.
Main features
- Compensation device: to remedy the systematic measurement errors usually occurring in the ultrasonic sensors, it is necessary to take into account the influence that the changes in temperature (and also in the atmospheric pressure and relative humidity to a negligible extent) have on the speed of propagation of the sound in the medium. This value does not influence the measurement of the hydrometric level in the ULS sensor produced because the changes in speed of propagation of the sound are compensated using a built-in temperature sensor. It is for this reason that the transducer is housed inside a pagoda structure that guarantees its ventilation. The measurement principle of the ultrasonic sensors is based on the analysis of the time elapsing between sending and receiving the ultrasound or on the control of receiving the sent signal. The emitter and receiver are positioned in the same housing.
- Easy maintenance: the benefits that our ultrasonic hydrometric sensor offers are not limited to precision, but also include simple and quick maintenance due to the engineering of the sensor that simplifies the phases. The only preventive activity consists of controlling the levelling of the sensor and in cleaning the target struck by the sensor. In fact, there must be no obstacles between the emitter of the sensor and the free surface of the water.
- Sturdy and reliable construction: lastly makes it an instrument with a long lifetime, which safeguards the customer’s investment. The instrument does not drift due to aging and requires no periodic calibrations.
- Components that can be added or be built into the product: none
