RPM-tester model 1206
This measuring instrument has been developed and built by ART-engineering after we found out that some older mechanical RPM-indicators could give a deviation of 200 RPM ore more. In cases where maximum RPM is needed to reach maximum climb, like on glider tow planes, a faulty RPM indication can result in a decrease of performance or even engine damage. When a substantial deviation is measured by calibration with this RPM-tester, either a deviation information card can be placed on the panel or the RPM indicator can be replaced.
The system is based on a photo tach sensor that reacts on a reflecting tape on one of the propeller blades. A digital RPM counter gives directly with a high accuracy the propeller RPM. This test equipment is developed for the non-type-certificated aircrafts, micro lights and experimental aircrafts
