Ultrasonic Autowide Sensor UHW051
OverviewConsistently 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 UHW051 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 UHW051 is a meandering web edge detector that saves time and labor, and is easy to use.
- Even if the detected material changes, the automatic thickness compensation function enables optimal detection
- An effective detection field of view of 56 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

ULTRASONIC SENSOR UH01 series
OverviewThe Ultrasonic Sensor UH01 / UH01A is designed especially to detect transparent film and photosensitive material in EPC(Edge Position Control)system.
It can detect the edge of a web with high accuracy, not affected by irregularities in the coating near the edge of transparent film and printed patterns, which is conventionally impossible by optical sensors. Combined with Nireco,s controller, an electrical EPC system and electro-hydraulic EPC system can be constructed. The UH01A is a version of our UH01 ultrasonic sensor with a longer internal length(the distance from the sensor center position to the inner side of the casing). Internal lengths of 200mm, 300mm, 400mm and 500mm are available. The internal length of the UH01 is 60mm (fixed).

Intrinsically Safe Anti-explosion Construction Systems
1. This field wiring shows connection with a Nireco-recommended safety barrier.
If a different safety barrier is used, be sure to select a suitable barrier and wire it correctly to avoid compromising the conditions for intrinsic safety construction.
2. Read "Instruction manual QJ3758.*-E" before beginning wiring work or using the equipment.
3. Carry out wiring work in accordance with the National Electrical Code ANSI / NFPA 70 and the Local Electrical Codes.
4. FM intrinsic safety construction Class I, Division 1, Group D, T4, Class I, Zone 0, AEx ia IIa T4.
