ROMER ABSOLUTE 75 2.5 METRE ARM

The 6-axis ROMER Absolute Arm 75 Series is designed for tactile measurements on a wide range of workpieces. With a measuring range of 2.5 metres (8.2 ft), it provides reliable touch-probe measurement and inspection of parts including sheet metal, plastic components and carbon fibre structures.

Key Features

Absolute Encoders

Switch on and start measuring without referencing or warm-up time.

Automatic Probe Recognition

Intelligent quick-change probes and a repeatable mount allow touch probes to be exchanged without the need to recalibrate.

Zero G Counterbalance

Minimises torque at the base of the arm, supporting mounting options including lightweight tripods, magnetic bases and vacuum bases.

SmartLock

Locks the arm safely in its rest position when not in use. It can also hold the arm in an intermediate position.

RDS Software with SMART Technology

Supports management of checks in the field, alongside temperature and shock monitoring.

Instant Operator Feedback

Acoustic and haptic feedback provide immediate information to the operator during use.

(1) The Point Repeatability Test is the reference test to determine measurement arm repeatability with ball probe. The cone is in front of the machine. Points are measured from multiple approach directions. The average point and the deviation of each point to the average centre are calculated. The result is the maximum range divided by two.

(2) The Volumetric Accuracy Test most accurately represents the reasonable expectations for machine performance in practical measuring applications since it involves measuring a certified length standard many times in several locations and orientations and compares the resultant measurements to the actual length. The Volumetric Length Accuracy Test is the most appropriate test for determining machine accuracy and repeatability. The result is the maximum deviation of the measuring distance less the theoretical length

All specifications according to B89.4.22

All probing specifications are achieved with a ROMER Absolute Arm mounted on a ROMER base plate or magnetic base and using a 15 mm steel ball probe with a length of 50 mm under stable environmental conditions

Calibration



Includes one year’s calibration.
