Operating Information
The product is designed for use in air and is not intended for acoustic measurement in liquids. Actual detection distance and resolution depend on drive conditions, receiver gain, target size, target material, installation and ambient temperature.
Selection Information
For selection, specify the target size, working distance, installation space, operating temperature, drive voltage and connection requirements.
