Hardware & Sensor/Transducer selection for measurement

This course is designed to introduce participants to a range of different sensor technologies and their connection, installation, and configuration. The Sensor Fundamentals course will enable you to select the correct sensor for a given application. Unlike other training courses that is mostly theoretical, our courses emphasize skills. We focus on hands-on real time training so participants can learn by doing, not just hearing. Our instructors bring a wealth of application experience, practical tips, and best practices to make your concepts clear.
