3 Product description
3.1 Product design
The sensor is designed for continuous in-situ determination of interfaces.
The sensor includes all necessary modules:
• Power supply
• The ultrasonic source emits the measurement signals.
• The ultrasonic receiver receives the measurement signals, digitalizes the signals and
converts them to a measurement value.
• The sensor microcontroller controls the internal operations and data transmission.
The preconfigured sensor can be used at a measuring point.
3.1.1 Measuring principle
A piezoelectric crystal is enclosed in a flat cylindrical plastic housing. When the crystal is
excited by an electrical voltage, it generates a sonar signal. This causes ultrasonic waves to be
transmitted at a frequency of approx. 650 kHz and at an angle of 6° to scan the separation
zones.
The measured variable is the time the transmitted ultrasonic signal needs to reach the solid
particles in the separation zone and return to the receiver. The separation zone is computed
after the maximum slope and the maximum signal amplitude.
A sensor version featuring a wiper is available to reliably avoid the buildup of deposit on the
sensor membrane.
