Diameter Gauges A Novel Kind of Diameter Measurement Based on "Multi-Source Device" Technology

MSD SERIES – A NEW ZUMBACH CONCEPT With the MSD diameter gauges, ZUMBACH introduces a new series of measuring heads for on-line diameter and ovality measurement and control. This new line complements the high-precision laser diameter measuring heads of the ODAC® series. The MSD models achieve their ideal efficiency in terms of price and performance specifically for applications in the cable and plastics industry. The experience of 55 years with on-line and off-line measurement and control technology has led to a product characterised by the most current and sophisticated technology and functionality...

MEASURING PRINCIPLE The measuring principle is based on the latest CMOS technology with several point-like LED's as light sources. The shadow of the object to be measured, originating from the various light sources, is projected on a line sensor. The line sensor calculates the position of the shadow, thus resulting in different measuring points. These points generate four fictitious shadow lines, which define a square enclosing the object to be measured. MSD 100 & MSD 200 * * Both figures only show the beam trajectory based on 2 light sources. Both the MSD 100 and MSD 200 models are equipped...

TECHNICAL DATA Model Number of measuring axis Number of LED sources Measuring field M 2) Min. object diameter Accuracy centric 3) Accuracy measuring field 4) 1) 4 axes for smaller products: MSD 100: measuring field ø 20 mm (.8 in.) MSD 200: measuring field ø 54 mm (2.1 in.) 2) M is the measuring field height. In practice, the largest object diameter equal measuring field height minus biggest error, minus instability of position. 3) Valid for object diameter bigger than "min. object ø" and smaller than 95% of the measuring field M. The centre of this object is in the middle of measuring field...
