TESA TECHNOLOGY Swivel probe TESATAST type 4251

Design: Metal housing, with rotating scale dial and patented shock absorber in the measuring instrument. Two rotating clutch discs in the lifting system protect against overload. Measurement is possible in two directions due to automatic switching of the movement. The consistent running direction of the pointer permits error-free reading; not sensitive to magnetic fields, movement with 7 rubies. Ball bearing lever system with 240° pivot range of measuring insert, very low measuring force.
Measuring force with measuring insert 12.53 mm: 0.15 N, with 36.53 mm: 0.06 N. Monoblock housing with 3 milled dovetail rails. Supplied with measuring insert M1,4 with Ø 2 mm, a wrench for measuring insert and a clamping shaft Ø 8 mm, in plastic case.

Application: Ideal for difference measurements, e.g. on the test plate, measurement of shape and position deviations, in particular of concentricity and axial run-out.
