All 34 portable measuring arms offered in six-axis touch-probing and seven-axis multi-sensor variants by LK Metrology, are now available as standard with a 4.5-inch diameter mounting ring that allows the unit to sit on a larger base (3.5-inch ring previously). The new Version 3 Freedom arms are subsequently capable of measuring to higher precision. LK can supply a mounting ring adapter if an existing user already owns an LK tripod or stand with a 3.5-inch mount. Mechanical, magnetic and vacuum fixing alternatives are available.

As previously, the latest mobile metrology solutions feature a lightweight carbon-fibre tubular construction. Position feedback arrives courtesy of absolute rather than incremental rotary encoders, with the arms available in three accuracy categories: Classic, Select and Ultimate. Each is now capable of significantly higher accuracy measurement of size, position and form, whether using a tactile probe or laser scanner. Probing accuracy carries certification to ISO 10360-12 with functionality guaranteed up to 40°C.

The work-hardened six-axis arms offer full IP54 protection from water splashes and the ingress of dust and particles, delivering reliable, repeatable 3D inspection and measurement in harsh industrial environments. Also provided is enhanced RDS v6.4 software running on Windows for communicating with the arm via Wi-Fi or USB. The software offers improved monitoring of parameters such as ambient temperature and stress on the articulated joints, as well as base vibration, displacement, tilt and inclination.

The seven-axis Freedom Arm v3 does not offer IP54 protection but is able to deploy a laser scanner and a tactile probe to enable multi-sensor metrology. An OLED touch-screen display provides the operator with convenient fingertip control, raising inspection productivity by avoiding having to go back and forth between the arm and a computer.
