Portable Measuring Arms

ROMER Absolute Arm - Portable Measuring Arms. ROMER measuring arms stand for maximum mobility in industrial metrology.

Portable Measuring Arms

A first in the world of portable measuring arms: The ROMER Absolute Arm features absolute encoders and is therefore the first measuring arm which does not require referencing before measurement. When the arm is turned on, it’s ready to go. 

ROMER produces a portable coordinate measuring machine which combines the entire experience of the Hexagon Metrology network.

Description

A portable measuring arm is a good investment. The time required to train users is minimal – even unpracticed personnel will produce reliable measuring results in a short time due to the user-friendliness of the ROMER Absolute Arm.

Inspection and control throughput is increased dramatically, and because the ROMER Absolute Arm helps to ensure quality, there is a fast return on investment.

With ROMER Absolute Arm increase productivity and minimise off-spec production – in the long term and with absolute efficiency.

Features & Benefits

ROMER Feature Packs

ROMER Feature Packs unfold the full potential of a portable measuring arm. These optional feature packs utilise the ROMER Feature Pack Port interface. All extensions are perfectly coordinated with the ROMER Absolute Arm and are part of an integrated system.
The ROMER Mobility Pack includes a battery and WiFi communication – maximum flexibility for the ROMER Absolute Arm.
The ROMER Scanning Pack is the interface for laser scanners. They connect directly to the arm.
Feature packs are thermally and mechanically stable, easy to exchange for the user and open for new technologies and additional accessories.

ROMER Feature Pack Port for data communication

The ROMER Absolute Arm has a specific standard for data communication. If required, with the ROMER Feature Pack Port interface, the Absolute Arm can be used as a fully wireless CMM.

RDS – the ROMER tool for software integration

RDS is the virtual image of a ROMER measuring arm. This software with its intuitive operation facilitates probe calibration and includes a diagnosis function for checking the measuring accuracy of the arm in compliance with international standards.

ROMER ergonomics - accuracy made easy

Carbon fibre structure. Absolute operational safety with SpinGrip and a handle with incorporated mouse function. Illumination of the part and an integrated digital camera are available upon request. Overall weight only 7.7 kg/17 lbs (2.5 m/8.2 ft. arm). The ROMER Absolute Arm is an all-round balanced measuring instrument. Its operation is a matter of routine after only a few hours, even in locations where traditional CMMs would never perform.

Infinite Rotation

ROMER’s patented infinite rotation of the principal axes allows a comfortable inspection of hard-to-reach areas.

Integrated Zero-G counterbalance

An optimized counterbalance reduces operator fatigue and delivers effortless control in all positions, including above and below the centreline.
