Ultrasonic Autowide Sensor UHW280
Overview
Consistently detects changes in the edge position of transparent/thin/reflective webs - over a wide field of view.
The ultrasonic Autowide sensor is able to detect -- over a wide field of view -- the edge of webs that are transparent or are thin films or have other qualities that make them difficult to be detected by optical sensors.
Not only is the ultrasonic Autowide sensor UHW280 resistant to changes in ambient temperature and humidity, this sensor for the detection of meandering web edges has outstanding features, including a function that automatically corrects the level of ultrasonic transmission when the thickness of the detected web changes.
The ultrasonic Autowide sensor UHW280 is a meandering web edge detector that saves time and labor, and is easy to use.

Feature
- Even if the detected material changes, the automatic thickness compensation function enables optimal detection
- An effective detection field of view of 280 mm
- An automatic correction function which minimizes the influence of changes in ambient temperature and humidity
- Can detect the edges of thin transparent films (3 μm or greater) over a wide field of view

The receptor is a CCD linear image sensor with 4,096 pixels. It is a fixed imaging element with 4,096 photo cells arrayed in rows at intervals of 7μm. Light that is partially shaded by the measurement subject passes through the lens to form an image on the receptor. Pulse signals are output with varied levels proportional to the amount of light falling on each pixel. That is the video signal, and it is output as a time series of pulse signals. From that video signal, the number of pulse signals exceeding a certain level is measured, and an analog voltage (0~5V) proportional to that measurement count (equivalent to the bright portion that receives light) is output.
