Applications
This 100KHz ultrasonic transducer can be used in high-frequency ranging systems, precision distance measurement, flow measurement, liquid level sensing, object detection, industrial automation, robotic sensing, parking detection, tank monitoring, and waterproof ultrasonic measurement equipment.
It is suitable for OEM and ODM projects that require a compact high-frequency ultrasonic sensor with narrow directivity, IP68 protection, and stable operation across a wide temperature range.
Working Principle
The ultrasonic transducer converts electrical signals into ultrasonic acoustic waves and converts reflected ultrasonic waves back into electrical signals. In a ranging system, the controller measures the time between transmitted and received echoes to calculate distance.
The 100KHz operating frequency and narrow 12°±2° beam angle help provide directional echo detection, making the sensor suitable for applications where focused measurement and reduced side interference are important.
Design and Integration Notes
For best performance, the transducer should be driven near its center frequency and matched with a suitable ultrasonic driver and receiver circuit. The acoustic path should remain clear, and the sensor should be aligned toward the target surface.
Measurement performance may be affected by target size, surface angle, material, temperature, humidity, airflow, mounting structure, and echo interference from surrounding objects.
When integrating this sensor into waterproof or outdoor equipment, confirm sealing structure, cable design, housing installation, drive voltage, detection distance, and environmental requirements before mass production.
