摘要： The invention relates to a device for detection and adjustment of the tension of a scraper chain of a chain conveyor, in particular of a face conveyor, having a tensionable return station, on which a spoked chainwheel to reverse the scraper chain, having chain links and scrapers attached thereto, is supported between the bottom race and the top race. The devices comprises having a sensor which determines the tension of the scraper chain at the return station. According to the invention, the sensor comprises a swivellable sensor body coupled with a shaft encoder, which sensor body in the top race is in contact with the upper face of the scraper chain in a measurement zone, with provision being made in the measuring zone for vertical play for the run of the scrapers and/or the chain links. The provided play preferably is being free or unlimited.
