ENSOUL TVG Tornado Touchscreen High-Precision Manual Torsion Tester

Overview

The ENSOUL TVG Tornado is a manually operated, high-precision torsion testing instrument engineered for repeatable and traceable measurement of application and removal torque on closures—primarily screw caps, pump dispensers, child-resistant packaging, and pharmaceutical vial seals. Unlike motorized or servo-controlled systems, the TVG Tornado employs a calibrated handwheel-driven mechanical architecture that eliminates variability from actuator dynamics, enabling direct operator control over loading rate and dwell time. Its measurement principle relies on a strain-gauge-based torque transducer integrated into a rigid, low-hysteresis load train, delivering stable readings with minimal thermal drift and long-term zero stability. The full-color capacitive touchscreen interface provides real-time numeric readout, graphical torque-time traces, and intuitive navigation without external peripherals—making it suitable for QC labs, packaging R&D facilities, and production line validation stations where simplicity, regulatory readiness, and tactile feedback are prioritized.

Key Features

• Manual handwheel operation ensures precise, operator-defined torque ramp rates and controlled breakaway detection—critical for evaluating cap seal integrity and tamper-evident performance.
• Four standard models covering 1.5–10 N·m range, each factory-calibrated to NIST-traceable standards with documented uncertainty budgets per ISO/IEC 17025.
• Touchscreen interface supports multi-language UI (English, Spanish, German, French), unit switching (N·m, lbf·in, kgf·cm), and dual-mode display (numeric + real-time curve).
• Password-protected administrator mode restricts access to calibration settings, alarm thresholds, and user account management—supporting GLP/GMP audit requirements.
• Five independent, user-configurable alarm conditions: upper/lower torque limits, pass/fail status, peak hold trigger, and dwell timeout warning—each assignable to visual indicators and audible signals.
• RS-232 and USB-B ports enable bidirectional communication with VectorPro Lite software for advanced data export (CSV, PDF reports), statistical analysis (mean, SD, Cp/Cpk), and SPC chart generation.

Sample Compatibility & Compliance

The TVG Tornado accommodates a broad spectrum of closure geometries via interchangeable fixture adapters—including flat-top, concave, hexagonal, and knurled caps ranging from 13 mm to 110 mm in diameter. Fixture mounting follows standardized DIN 55472 and ASTM D3474 fixture alignment guidelines to minimize eccentric loading errors. All test methods comply with ISO 8504-2 (packaging—torque testing of closures), USP (performance verification of torque devices), and FDA-recommended practices for packaging integrity assessment under 21 CFR Part 211. Calibration certificates include as-found/as-left data, measurement uncertainty statements, and traceability to NIST SRM 2196 (torque calibration standard).

Software & Data Management

VectorPro Lite software serves as the official companion application for the TVG Tornado, providing secure, audit-ready data handling in accordance with FDA 21 CFR Part 11 requirements. It enforces electronic signature workflows, automatic audit trail logging (user, timestamp, action, parameter change), and role-based permissions (Operator, Supervisor, Administrator). Test records are stored in encrypted SQLite databases with optional cloud backup integration. Raw torque-time datasets support FFT-based noise analysis, derivative calculation for slip-point identification, and batch comparison across multiple lots or suppliers—facilitating root-cause investigations during CAPA processes.

Applications

• Pharmaceutical packaging: Validation of child-resistant closure torque specifications per USP and EU Annex 15.
• FDA-regulated consumer health products: Routine QC testing of nasal spray actuators, inhaler canisters, and topical tube caps.
• Food & beverage industry: Verification of tamper-evident band integrity and consistent capping torque across high-speed fill lines.
• Packaging R&D labs: Comparative evaluation of liner material friction coefficients, thread geometry effects, and environmental aging impacts on torque retention.
• Contract manufacturing organizations (CMOs): Documentation-ready torque verification for client-facing regulatory submissions (e.g., ANDA, MAH dossiers).

FAQ

Is the TVG Tornado compliant with FDA 21 CFR Part 11 for electronic records?

Yes—when used with VectorPro Lite software, the system supports electronic signatures, audit trails, and role-based access controls required under Part 11.
Can the device be recalibrated in-house?

No—recalibration must be performed by an ISO/IEC 17025-accredited laboratory using NIST-traceable reference standards; field adjustments are disabled in user mode.
What is the maximum sampling rate for torque-time curve capture?

The internal acquisition engine samples at 100 Hz with 16-bit resolution, ensuring accurate capture of transient events such as cap break-loose peaks.
Does the TVG Tornado support custom test method scripting?

Not natively—the instrument operates on predefined test modes (application, removal, peak hold); advanced scripting requires VectorPro Pro (sold separately).
Are fixture adapters included with the base model?

Standard fixtures for 20 mm, 28 mm, and 38 mm closures are supplied; specialized adapters (e.g., for aerosol valves or syringe plungers) are available as optional accessories.
