Measurement Software

Hexagon Manufacturing Intelligence (North Kingstown, RI) has launched PC-DMIS 2017 R2, the latest edition of their popular measurement software. This is the second of two major releases scheduled for PC-DMIS in 2017, with continued service pack updates to ensure maximum reliability of the platform.

PC-DMIS 2017 R2 introduces Slideshow for INSPECT software, allowing users to create unlimited customizable layouts with inspection results populated during measurement. INSPECT software was first introduced with PC-DMIS 2017 R1 in January 2017 as a simple front-end for PC-DMIS Measurement Routines. The optional Slideshow tab (additional license required), can display multiple slides of dimensional and informational labels whenever users execute a measurement routine. The native mesh resolution is improved from import to visualization. PC-DMIS 2017 R2 makes it easier to apply a color map to the mesh data object and create annotation points, align mesh data objects to the CAD model or align a mesh to another mesh object. The Vision Live View now displays which features have already been programmed.

Ultra-Low Noise Pluggable PSUs

Originally developed as a custom solution for highly sensitive electronic measuring equipment designed to capture experimental ring accelerator data, the new Eplax 3U 7HP 19” pluggable PSU with output noise levels below 4 mV p-p is now available as a standard product through Verotec Inc. (Manchester, NH) for any high sensitivity application where ripples and spikes on the output voltage must be as low as possible.

The dual output AC/DC power supply unit is rated at 45 Watts, with outputs of +15 V/ 1A and +24 V/ 1.2A. A special filter network for the output rails reduces ripples and spikes to the absolute minimum without violating the unit’s slimline 7HP width. The noise voltage for all loads from idle to full load is lower than 4 mV p-p. Using the filtering technology developed for this design, ultra-low noise power supplies with other outputs can also be supplied.
