UHW280 Nireco | Ultrasonic Autowide Sensor
Cảm biến canh biên dạng siêu âm cho ngành sản xuất bao bì và giấy
Overview UHW280 Nireco
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 UHW280 Nireco
- 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
