M 3 aS防震型量表 M 3 S量表和M 3 aS量表通过高性能防震保护具有超常的使用寿命。通过附加在测量杆和轴套之间的防震机构，使轴套受到的振动不会传导至量表的传动轴。即使是震动条件下使用，也几乎不会对高精准度的的测量有所制约。 M 3 T和M 3 aT型具有相同的技术参数，但不防震，它们的结构图与M 2 T量表相同。 测量杆及下轴套由硬质不锈钢制成 M 3 S防震型量表 分度值                     0.005mm测量范围                         5mm周值                            0.5mm表径                          Ф58mm下轴套                          Ф8h6执行标准                   DIN 878测量杆                             研磨 Dial Gauge M 3 a SshockproofDue to their effective shockproof system these Dial Gauges have an exceptionally long service life. A gearrack sleeve covering the length of the spindle is arranged and sprung in such a way that shocks against themeasuring insert are not transferred to the movement. The Dial Gauges are robust in operation.Their precision is maintained with practically no limitations.Our models M 3 T and M 3 a T have exactly the same technical data, but are not shockproof.Spindle and stem are made of resistant stainless steel.Precision Dial Gauge M 3 a S shockproofReading 0,005 mmRange 5 mmRange per revolution 0,5 mmBezel-Ø 58 mmStem-Ø 8 h 6Dimensions and accuracy according to DIN 878Spindle lapped
