Technical Specification

The Vertex VMS range of digital height gauges supports both 1D and 2D measurement. Some of the key capabilities for 1D measurement are outlined below;

  • Comprehensive measurement of heights, drops, internal and external diameters, TDC (Top Dead Centre), BDC (Bottom Dead Centre), internal gap, external gap and centre to centre measurement
  • Multiple datum facility, up to 8 assignable datums
  • Comprehensive probe qualification
  • Squareness measurements from front and side of surface
  • Scribing facility for layout work
  • Print function for ‘ALL’ or ‘SELECTED’ output
  • The Vertex VMS performs all functions as fully autonomous routines with no pipes of trailing wires. If communications are needed with peripheral devices such as a printer or network, then this is achieved through the RS232C or USB facility.

2D Measurement

The Vertex range of digital height gauges also offers 2D measurement to supplement the extensive 1D functionality with powerful onboard processor firmware. 2D Capabilities Include;

  • Rectangular and polar coordinates
  • Alignment of features
  • PCD (Pitch Circle Diameter) measurement

Electronic Control Unit (ECU)

The programmable 3 axis ECU is reminiscent of a “hole in the wall” display. The viewing area is kept clear apart from the key information being displayed. An ‘orbital keypad’ as the description implies is active around the viewing area offering the user an intuitive aspect with regard to software commands.

The viewing screen is produced from a clear, robust polycarbonate material. The tactile keyboard indicates to the user that a command has been made.

Ergonomic design provides a platform for accessing the multifunctional application software.
