Atlas Copco ACTA 4000 Torque Calibrator – Precision Calibration for Industrial Tools

The Atlas Copco ACTA 4000 torque calibrator is a dedicated calibration instrument designed for verifying and adjusting torque tools used in assembly and maintenance operations. This calibration equipment combines robust mechanical construction with advanced electronic measurement technology to provide accurate, repeatable results that meet ISO and ASTM standards. The ACTA 4000 is suitable for calibrating manual torque wrenches, power tools, and torque sensors across a wide range of industrial sectors including automotive, aerospace, heavy machinery, and energy.

Key Features of the Atlas Copco ACTA 4000

The ACTA 4000 torque calibrator features a high-rigidity transducer mounting system that minimizes deflection during measurement. Its integrated electronics offer real-time torque readout with peak capture and tracking modes. The calibrator supports both clockwise and counterclockwise torque measurement, enabling full bidirectional calibration. A large graphical display provides intuitive menus for setup, calibration routines, and data review. The unit includes memory for storing multiple calibration profiles and test results, which can be exported via USB or RS-232 for documentation and traceability.

Technical Specifications and Measurement Ranges

The Atlas Copco ACTA 4000 offers several interchangeable torque transducers to cover different torque capacities. Typical ranges extend from 0.5 N·m to 4000 N·m, depending on the transducer selected. Accuracy is specified at ±0.5% of reading for the majority of the range, with resolution down to 0.01 N·m on lower-capacity sensors. The system includes automatic temperature compensation to maintain performance in varying workshop conditions. Overload protection is built into the electronics to safeguard the transducer during accidental over-torque events.

Calibration Modes and Operation

Operators can choose between manual calibration mode, where the tool is operated by hand while the display updates, and automated calibration sequences that guide the user through step-by-step procedures. The ACTA 4000 supports first-peak and final-peak detection for click-type and cam-over torque wrenches. For power tools, the calibrator can be configured to measure average torque over a defined period or capture the maximum pulse torque. The unit also offers a continuous monitoring mode for process validation and tool drift analysis.

Industrial Applications and Benefits

In production environments, the Atlas Copco ACTA 4000 ensures that fastening tools are operating within specified tolerances, directly impacting product quality and safety. Regular calibration with this equipment helps reduce scrap, rework, and warranty claims caused by improper torque. Maintenance departments rely on the ACTA 4000 for periodic verification of tool performance, enabling proactive replacement of worn components. The data logging capability supports ISO 9001 and IATF 16949 documentation requirements, providing audit-ready calibration records.

User Interface and Connectivity

The ACTA 4000 is equipped with a backlit LCD that displays torque values in N·m, lb·ft, lb·in, or kg·cm. The menu structure is designed for quick navigation, with programmable function keys for commonly used tasks. Connection ports include USB-B for PC communication and RS-232 for integration with data acquisition systems. Optional accessories include a remote display, footswitch, and calibration software for advanced data management. The unit is powered by standard AC mains or optional battery pack for field use.

Maintenance and Reliability

Routine maintenance for the ACTA 4000 involves periodic zeroing and verification using certified reference transducers. The housing is constructed from impact-resistant materials and sealed against dust and moisture to IP54 rating. Recalibration intervals are typically recommended every 12 months, depending on usage intensity. Atlas Copco provides global service support with exchange transducers and repair services to minimize downtime. The calibrator is built to withstand the rigors of daily shop-floor use while maintaining long-term stability.

Choosing the Right Transducer

Selecting the correct transducer for the ACTA 4000 is essential for achieving optimal measurement accuracy. Atlas Copco offers a range of square-drive and hex-drive adapters to accommodate various tool interfaces. For small fasteners, lower-capacity transducers provide finer resolution, while high-capacity models are designed for heavy-duty bolting applications. Users can also order custom adapters for non-standard tool geometries. The calibrator automatically recognizes connected transducers and loads the appropriate calibration coefficients.

Compliance and Standards

The Atlas Copco ACTA 4000 is manufactured to comply with international calibration standards, including ISO 6789 for torque wrenches and ISO 5393 for power tools. The instrument’s measurement traceability is backed by factory calibration certificates that are NIST-traceable upon request. This compliance ensures that the ACTA 4000 can be used in regulated industries where documentation and accuracy are critical. The calibrator also meets EMC requirements for industrial environments, minimizing interference with nearby electronic equipment.
