With its BMP series, Balluff (Florence, KY) has added a new intelligent displacement sensor which provides not only the absolute position signal for the stroke travel of a piston via IO-Link but also information about the sensor status and the current ambient conditions. For example, it monitors variables like sensor temperature and the number of starts, and issues warnings when a configurable limit value is violated. An internal counter continuously monitors the operating hours over the entire life of the sensor, both since the last service and the last start-up. This makes it possible to plan for a possible needed replacement at the next service interval.
Preferred applications include those where the exact execution of a defined piston stroke is essential for the process and product quality, such as assembly, handling and factory automation.
