Helixa-XT Torque Tester

The Helixa-XT Torque Tester is designed for precision design applications, where torque forces may be very small and where accuracy is paramount.  The Helixa accepts interchangeable intelligent torque cells for measurement from just a few mN.m up to 6 N.m, with a resolution of 1:6,500 and an accuracy of ±0.5% of full scale. Our experienced engineers can design and manufacture custom fixtures for your specific sample profiles.

The Helixa-XT precision torque tester provides the ideal solution for measuring very low to medium torque variations on a variety of delicate or finely-engineered products. Its counterbalancing mechanism allows the removal of axial force, whilst also enabling the application of precise top-load or tensile force when required. The drive spindle can be user-aligned for precise concentricity with the intelligent torque cell. Our experienced engineers can design and manufacture custom fixtures for your specific sample profiles. The Helixa accepts interchangeable intelligent torque cells for measurement from just a few mN.m up to 6 N.m, with a resolution of 1:6,500 and an accuracy of ±0.5% of full scale.

Key benefits:
• Precision: measure low-torque values from just a few mN.m up to 6 N.m
• Alignment: each fixture may be precisely aligned with the torque cell axis for extreme low torque measurement
• Exacting: counterbalance eliminates the weight of a grip being applied to a sample
• Versatile: top-loading capability to apply a predefined axial load, particularly suited to push-down twist testing child-resistant closures
• Flexible: complete with a set of standard accessories for securing even the lightest samples, with custom fixtures also available.

Applications for which the Helixa has been designed include:
• Luer fittings (slip and lock)
• Dosage-dial drug delivery devices (e.g. insulin pens)
• Light and miniature torsion springs
• Electronics rotary controls and components
• Fine and high-performance bearings
• Child-resistant closures (CRCs)
• Cosmetics twist-dispensers (e.g. lipsticks)

Emperor™ Software

Emperor torque testing software runs on any Windows computer. The software takes full control of the test frame motor whilst simultaneously collecting data from the ITC torque sensor and angle encoder. Easy-to-use software with almost limitless freedom to design and customise torque tests to suit your needs. 

Key features

  • Intuitive user interface
  • Console mode for operators
    Dedicated mode for the production line environment – designed for routine testing with minimal training.
  • Realtime graph plotting
    Measurement data is displayed on a graph as the test runs, so that the user can see exactly how the specimen is performing. Data from the ITC torque sensor and angle encoder is collected by Emperor torque software at an impressive 1,000 times per second (1 kHz).
  • Display measured and calculated values
  • Clear pass/fail indication
    A clear pass (green) or fail (red) indication leaves an operator in no doubt about the status of each specimen, based on your test standards.
  • Standard and customisable report templates
    A powerful reporting module allows you to configure test reports to present data the way your customer wants to see it.
  • Print results to Adobe PDF format
  • Export data to Excel and SPC packages
