Ultrasonic level sensor
0.3 - 4 m | NUK-4-T
E.L.B. Füllstandsgeräte Bundschuh GmbH + Co.
The ultrasonic level sensor transmits ultrasonic pulses in quick succession
which are reflected from the medium's surface. The time interval from transmission to reception of the reflected signal is measured exactly.
The impulse running time is directly proportional to the distance between
the level sensor and the medium surface. A microprocessor evaluates the echo signals and measures the filling level. Changes in the ultrasonic speed caused by changing temperatures are compensated.
The integrated software enables the useful echo to be filtered out and evaluated, even under unfavourable conditions. Thus it is possible to make reliable measurements in the vicinity up to a point just before the sensor. The electronics are accomodated in a waterproof plastic casing. The casing is resistant to corrosive materials and can tolerate high temperature fluctuations.
