bks-Sensor - Great performance on the edge

microsonic: Edge sensors are required for web control to detect the edge of the web material and maintain it on the correct lateral position. With materials such as highly transparent foils, light-sensitive materials, materials with greatly varying transparency and paper subject to high paper dust loads, ultrasonic solutions offer considerable advantages over the optical measuring principle.

The web material covers the receiver more or less consistently. Depending on the coverage degree, the electronics issue an analogue signal of 4-20 mA.

The bks edge sensor delivers the analogue signal with a resolution of 0.025 mm and has an operating range of 6 mm. The manufacturer specifies an accuracy of ± 0.1 mm for constant ambient conditions. The sensor’s very compact design with a fork width of only 30 mm and a depth of 33 mm facilitates its application in control systems and machines with small mechanical dimensions.
