Separate type VL-50S - B Because the measuring unit and the display unit are separate, they can be integrated into the user's measurement system. An optional dedicated stand is also available. Constant measuring force principle An unba lance d , para l l e l - l ink s t ruc tur e enab l e s t he L i temat i c to of fer a l ow and cons t ant mea sur ing for ce . The Litematic's measuring force is not provided by a spring but comes from a struc ture resembling a balance scale. We call this a "parallel linkage." A motorized slider carr ying the linked spindle moves down it s guideway while the linkage is suppor ted on a stop, as shown in Fig 1. When the spindle contac t s the workpiece (Fig. 2) it moves the linkage up of f the stop and the motor is halted. At this point the linkage is now suppor ted by the workpiece, and thus a constant measuring force is applied. Litematic VL-50S-B Litematic VL-50-B F i g. 1. T he sp indl e move s downwards towards the wo r kp i e ce. F i g. 2. T he sp indl e l i f t s the l inkag e of f the s top into the measur ing p o s i t i on. The contact point on the spindle touches the workpiece, lifting the linkage off the stop and halting the motor that was lowering the spindle, thus applying a constant force to the workpiece.

3 If the workpiece is soft the risk of indentation may be reduced by replacing the standard contact point with one of larger radius, such as an optional carbide-ball type. F or this t ype of workpi ece, the smal l es t measur ing force avai labl e is recommended. If the workpiece flexes, making accurate measurement impossible, using a type with a larger measuring force or adding a weight to the spindle may be effective. T he L i temat i c c an be us ed as a high - precision displacement gauge. Bec aus e the measur ing force is smal l, deformat ion of the workpi ece c an be minimized.

Mounting this contact point should be custom-ordered from Mitutoyo. Note: Motor life is approximately 100,000 operations, after which replacement is advisable. This maintenance factor is particularly important to bear in mind when the machine is used frequently, such as on a production line.

This requires special order. One of the notable characteristics of the Litematic is its small measuring force (0.01 N or 0.15 N models). However, depending on the characteristics of the workpiece, i t may not be possible to transmi t a sufficient measuring force and the contact point may appear suspended. To solve such a problem, optional weights are available that attach to the spindle to achieve the appropriate measuring force without damaging the workpiece.
