"Best-in-class“ Electronic Rotary Limit Switch: The Successful Cooperation of Baumer and B-COMMAND
Baumer Optronic GmbH Posted 04/23/2015
A common technology project in windpower was successfully completed: electronic rotary limit switch primeCAM with SIL2/PLd certification is the result of the joint development and close cooperation of Baumer and B-COMMAND. Merging the high innovation power and profound expertise of each partner, the project was successfully finalized with primeCAM certification and start of production. The outcome of common commitment: A "best-in-class" electronic limit switch with SIL2 certification that sets new benchmarks in precision and setup.
Baumer and B-COMMAND share a longstanding and close partnership which has brought up innovative and customer-oriented solutions for the windpower industry. Their core competencies in technology expertise, detailed application know-how and international alignment assimilated into the development of the new electronic limit switch and make primeCAM meeting all of the ever-growing specific requirements on safety, precision and system integration.
For many years, B-COMMAND has been developing and manufacturing systems for position measurement and cable-twist-protection at wind turbines. "Particularly when it comes to mechanical limit switches, we have been deploying Baumer encoders for many years since we trust in their very high quality standards“, explains Mr. Horst Lau, Managing Director B-COMMAND. An even more close-knit relationship in technology was the next logical step. The company headquartered in Hamburg is a leading manufacturer of rotary limit switch systems for yaw and pitch control with far-reaching contacts in the windpower industry.
Baumer, leading at international level in sensing technologies, has likewise established as a competent partner for reliable sensor solutions in windpower. "With this cooperation we further expand the Baumer market position and enhance our application knowledge for continued development of more high-innovation sensor solutions”, underlines Joachim Acker, Head of Sales of the Baumer product segment Motion Control.
primeCAM, the jointly developed electronic limit switch, combines the benefits and proven principle of conventional mechanical limit switches with cutting-edge encoder technology. Both companies are convinced that primeCAM marks the dawn of a new era of electronic limit switch systems with versatile function libraries, configuration options and installation capabilities. "With primeCAM we succeeded in creating a product platform combining safe cut-off by electromechanical relay with ultimately precise position feedback supplied by optical encoder", says Jan Schwonbeck, Key Account Manager B-COMMAND. Integrating even more safety tools and diagnostics for all safety-relevant components, primeCAM ensures extremely safe performance of wind turbines while improving existing safety concepts and simplifying implementation of the machine directive. Already in the standard version, primeCAM provides multiple interface capabilities and hence enables easy integration into existing contol and network systems.
Based on an optical absolute encoder developed by Baumer, primeCAM operates with an absolute accuracy of 0.1°. "And this way opens up a completely new potential in limit stop control and position feedback at wind turbines and other industrial installations“ adds Phillip Kaim, Product Manager Baumer. The primeCAM design and integrated components were selected under particular windpower aspects to match both onshore and offshore application requirements. This product novelty is the first to allow for limit switch contact monitoring by absolute encoder diagnostics.
