Passameters can be described as adjustable snap gauges, which can also be used for measuring rotation-symmetric parts, as well as for measuring thicknesses and lengths.
Technical data
• Graduation precision indicator 1 µm / 2 µm
• Scale division size ~ 0,8 mm
• Display range ±70 µm / ±140 µm
• Constant measuring force 5 -10 N
• Free stroke > 2,5 mm
• Measuring surface diameter 10 mm
• Surface flateness = 0,3 µm
• Parallelism of surfaces 200 mm use series 820. Special versions upon request.
Benefits
• Replaces many fixed gauges
• Permits fast comparative indicating measurements thanks to gauge integration
• Very easy to calibrate using the parallel gauge blocks
• Low measuring uncertainty
• Almost constant measuring force across the entire application range
• Comfortable series measurements by presetting measuring values and adjustable tolerance marks
• Requires little space during measuring thanks to precision indicator being integrated into external micrometer
Application
• to measure rotationally symmetric components, e.g. shafts, axles and bolts
• for thickness measurements and length measurements
