Wide Array Sensors for Narrow Web Applications
BST North America will use Label Expo to demonstrate the many uses in narrow web for its AccuWeb brand WideArray edge sensors. WideArray sensors feature large detection ranges – up to 18½” - to accommodate variations in web width. As a result, web widths can be changed on the fly, eliminating the need to physically reposition edge sensors, which means time savings and reduced downtime. They also allow the operator to change web position with the touch of a button. WideArray sensors self calibrate, so they are ideal for applications with many web width changes or applica- tions needing frequent adjustments of the web position. Traditional optical edge sensors are highly sensitive to build up of dust and other contaminants, and traditional ultrasonic sensors react strongly to changes in air temperature and vertical web flutter. WideArray sensors eliminate both of these limitations.
New Dual Edge Technology
New DualEdge ™ Technology allows a single WideArray edge sensor to monitor both edges of the width web simultaneously, for highly
Every WideArray sensor features AccuWeb’s patented Compensated Array Technology, which automatically compensates for dust, changes in temperature and humidity, as well as web flutter variances. As a result, the Infrared WideArray is ideal for non-woven applications, where dust and lint are common problems. WideArray sensors also eliminate the need for mechanical edge seeking devices, and they have no moving parts, which means no maintenance.
accurate centerline guiding of web widths up to 18.4 inches. They are used with the EVO 150 controller, a very compact package that offers many communication protocols, and is capable of oscillation, electronic guide point adjustment, web width measurement and web position monitoring. WideArray Sensors can be seen at Label Expo in the BST North America booth, # 837.
