| Abstract | ||||
| This paper introduces a full study to extend the capacity of a force sensor to three times its original capacity based on the build-up principle. The force sensors that have good metrological characteristics are costly devices. Such devices could fail as soon as the load exceeds its designed capacity. For covering a wide force measurement range, several force sensors shall be available. The systems that are designed to work over a wide force measurement range such as the system under study are a good replacement for many force sensors. It is expected that using a build-up system based on a single-active force sensor will be an advantage from the cost point of view. The metrological validation of the system was proved through analyzing experimental results, which are obtained during the test of a single-active sensor build-up system. The system achieves class 1 according to ISO376:2011. Further, as an excess step for the validation of the system under study, the new system based on a single-active force signal was used as a reference to calibrate a 2500 N force measurement sensor. It is found that the maximum measurement error is about 0.23 %. | ||||
