Captures displacement of transparent/ thin / reflecting webs in a wide view

The ultrasonic autowide sensor detects edges of transparent thin films etc. which are difficult to detect with an optical sensor in a wide view range. Ultrasonic Autowide sensor UHW051 is a meander detector having excellent features, including the functions of reducing the effects of change of the ambient temperature and humidity and correcting the ultrasonic permeation quantity automatically when the sensed material thickness changes. Ultrasonic Autowide sensor UHW051 is a meander detector which attains the "power and labor saving function" and easiness of use.
