FlatPack® Ultrasonic Sensor for Uneven Solid Material Level Monitoring

Massa Products Corporation: The MassaSonic® FlatPack® 95 kHz sensors is a low profile ultrasonic transmitter module. It is optimized to offer continuous non-contact distance measurement of pastes, fluids, or uneven solid materials in constrained working zones for application ranges from 4″ (100 mm) to 13′ (4 m). Featured here is the long range model, a shorter range model with a 1” (25 mm) dead band is available.

Adding customized dual-transducer ultrasonic technology and processing algorithms, all FlatPack® offer precision measurement for factory automation, warehouse materials control, pipe and conveyor belt blockage or tank and silo level applications. These Sensors perform extremely well in uneven surface or turbulent applications.

The FlatPack® 95 kHz sensor is ideal to monitor irrigation areas, solid material in silos or control feed rate into crusher equipment hoppers. The unique dual transducer design has a 15° system beam angle, so it’s not likely that the maximum range capabilities will be greatly affected by solid materials with non-uniform surfaces, as occurs with single transducer sensors with narrow beam angles.

The FlatPack® Sensors are IP68 rated, RoHS and CE compliant. These field proven designs come in a PVC housing ideal for use in all-weather resistant moderate chemical environments from -40°C to 70°C. An incorporated mounting plate with pre-formed holes is provided for easy installation and are powered by 12 – 24 VDC with an option for 0 – 10 V or 4 – 20ma output.  All models include continuous temperature compensation to guarantee measurement accuracy and precise speed of sound calibration. Other user-friendly features include diagnostic and monitoring outputs, protection from over voltage, short circuits, and reverse polarity.
