Special-purpose BMD
2R BMD with 2 entry grooves (extra charge) This option prevents jamming when the BMD is retracted from ribbed workpieces or interrupted bores. Basic types: Nom. diameter range: Order suffix:
S, D, FB, S-FB, L 7.0 - 270 mm 2R
Sample order: Bore 10 H6
Order Code BMD-S6-CR-10.0-2R
3P 3-point BMD (extra charge) Due to its specific design, the gauging accuracy of the 3-point BMD is slightly less than that of the 2-point gauge (see 81). Therefore, a 2-point plug gauge should be used wherever possible.
3-point plug gauges are required in order to detect polygonal shape defects. The gauging contacts are spaced at 3 x 120°. Different spacing available on request. The inner probe is mounted on a pendulum bearing in order to allow the gauging unit to center itself in the bore. Basic types: Diameter range: Sample order:
S, D, L 8.0 - 100 mm BMD-S10-CR-35.0-3P
The dimensions of the BMD correspond to those of the basic types in Series 6 and 10.
SO-TA BMD with depth stop (extra charge) 3 carbide stop bolts set at 3 x 120° angles. Basic types: S, D, S-FB, L-FB, FB Order suffix: SO-TA-L3 Sample order: BMD-D10-CR-28.0-SO-TA-L3 = 11 Please indicate dimension L3 in your order.
