Manual Gauges for External Diameters

M1 STAR™ OD - M3 STAR™ - M4 - M4 STAR™ - QUICKSNAP™

Marposs offers a complete range of variable gauges for manual measurement, available with mechanical orelectronic measurement transducers, for high-precision control of external diameters, pins and between shoulders or close to shims on crankshafts, drive shafts etc. The Marposs range of products for external diameters represents the most advanced and reliable solution currently available on the market.

Manual Gauges for External Diameters
BENEFITS
  • best metrological performance guaranteed on every gauging diameter
  • intuitive and easy to use; the design ensures linearity over the entire measuring range and allows zeroing with a single master
  • robust and constructed to withstand shocks
  • it is able to meet every need by connecting, wired or wireless, with a variety of displays or data process devices (both analog and digital dial gauge or indicator; both Marposs and commercial industrial computers)
  • allows the transmission and storage of the data on industrial PCs for statistics analysis
  • components designed to guarantee serviceability and  reparability in the event of wear or failure 
  • wide range of options for optimum measurement ergonomics
DESCRIPTION

M4 and M4Star are the ideal solutions for external diameter measurements, with both mechanical measurement with use of an indicator, and electronic measuring, using hard-wired or wireless transmission systems. Using the customisable measurement depth, the system may be used to measure diameters in the proximity of shoulders. The gauges, which consist of a ring body and a sturdy nosepiece, were designed to maintain their technical specifications, even under the severest operating conditions.

M3Star and QuickSnap are manual snap gauges designed for measuring external diameters between shoulders on crankshafts, camshafts and similar components. These gauge models are simple to retool, so that it is possible to measure different diameters using the same device, and  are available in indicator, hard-wired and wireless versions.

M1Star OD is the solution for external diameter located in a recess (e.g. the external diameter of a collar located in a recess inside a transmission case). It is designed for compatibility with the M1Star range of accessories.

TECH SPECS
  • repeatability: <1 micron
  • application range: 4 mm to 125 mm for M4, M4Star and M1Star OD
  • application range: 3 mm to 150 mm for M3Star and QuickSnap
  • the contacts are available in a variety of materials and radius, depending on the material and the roughness of the diameter to be measured
  • only one master  is required for zero-setting
  • Lumberg SV50/6 connector
  • compatible with Marposs and other manufacturers’ electronic units
  • the electronic gauges can be supplied with LVDT or HBT transducer
  • M4Star  allows the user to customize the measurement depth between 1 mm and 6 mm
VERSIONS

Both M4Star and M3Star external diameter gauges can be equipped with analog and digital dial indicator, either analogue or digital, and hard-wired or Bluetooth® wireless transmission systems, whereas the M4 gauges are available in hard-wired and LVDT signal versions.

M1StarOD was designed to be compatible with the M1Star range of accessories, i.e. handles for comparators or linear probes, handles with cables, or the innovative I-Wave2 handle, complete with colour screen for displaying measurements in real time and Bluetooth® transmission system.
