Adjustable snap gauge 3902

The digital Passameter 3902 for the inspection of narrow manufacturing tolerances is featured by very high accuracy and a big, direct measuring range of 4 mm. Technical data • Measuring surfaces 10 mm • Flatness / parallelism < 0,3 µm / < 0,5 µm • Repeat accuracy < 0,3 µm • Resolution 0,1 µm • Measuring stroke of the measuring probe 4 mm • Measuring force 12 - 18 N • Weight of the 0 - 30 mm model 0,9 kg • Protection class IP 65 System description The digital Passameter with a solid measuring equipment body and a novel inductive measuring system achieves a very high measuring accuracy and repeatability. The weight of the measuring tool rests on the workpiece due to the anvil which can be adjusted from the top. The measuring probe which is moved in from below has a free stroke of 4 mm and ensures a very high repeatability thanks to its constant measuring force. The display resolution is 0.1 µm. The large measuring surface of 10 mm ensures stable support on the specimen. All recorded measuring values can be processed externally with an optional wireless module. The adjustable tolerance function simplifies the use in serial measurements. Programable with the optional software FMS-SD1 direct via cable. All internal functions like calibration, LED function and colors, indication bar, measuring mode or password lock can be done via PC.
