bks ultrasonic edge sensors

Product catalog summary

Overview
The bks ultrasonic edge sensors are designed for contact-free web edge scanning of sound-impermeable materials such as foils and paper. These sensors are ideal for applications involving highly transparent foils, light-sensitive materials, and environments with high paper dust loads.

Key Specifications

Compact design with a fork width of 30 mm and depth of 33 mm.
Resolution of 0.025 mm and relative accuracy of 0.1 mm.
Response time of 4 ms and working range of 8 mm (±4 mm).
Analogue output options: 4–20 mA and 0–10 V.
Robust metal housing suitable for harsh conditions.

Functional Principle
The sensor operates using a fork design where an ultrasonic transmitter emits sound impulses detected by a receiver. The material passing through the fork attenuates the signal, which is evaluated to determine the edge position. Calibration can be done using a Teach-in button with two methods: either by freeing the fork from material or aligning the web edge for 50% coverage.

Technical Features

Operating voltage: 20 - 30 V DC with reverse polarity protection.
Transducer frequency: 200 kHz.
Class of protection: IP 65.
Operating temperature range: +5°C to +60°C.
Storage temperature range: -40°C to +85°C.
Weight: 140 g for the standard model.

Models and Variants

bks-3/CDD: Features two switching outputs, each with a capacity of 500 mA, and a response time of 2 ms.
bks-6/12/CIU: Offers a larger fork width and depth, with an analogue output of 4-20 mA / 0-10 V, and a response time of 2 ms.
bks-3/CIU: Similar to the bks-3/CDD but with analogue output capabilities.

Additional Features
The sensors come with a push-button for settings and can be parameterized using the LinkControl adapter LCA-2. They feature LED indicators for center position and deviation, and the LEDs can be switched off for light-sensitive applications.

Note
The specifications are subject to change and are presented descriptively without warranty of product features.

Description The bks ultrasonic edge sensor is a fork sensor for scanning the edges of sound-impermeable materials such as foil or paper. This is why the bks is ideally suited for the web control of highly transparent foils, light-sensitive materials, materials with greatly varying transparency and paper subject to high paper dust loads. The functional principle The fork’s lower leg is equipped with an ultrasonic transmitter which cyclically emits short sound impulses, which are detected by the ultrasonic receiver arranged in the upper fork leg. Material passing through the fork covers this sound...
