Overview
The Jianhu DV-500E is a precision-engineered desktop electromechanical single-column tensile testing machine designed for routine mechanical property evaluation in quality control laboratories, R&D facilities, and contract testing environments. It operates on a closed-loop DC motor-driven actuation system coupled with a high-rigidity precision lead screw transmission mechanism—enabling smooth, low-noise axial displacement with minimal backlash and thermal drift. The system adheres to fundamental principles of uniaxial quasi-static mechanical testing per ISO 6892-1 (metallic materials), ASTM D638 (plastics), and ISO 7500-1 (calibration of force-measuring systems), supporting both tension and compression modes within a defined 500 N load range. Its compact footprint and modular fixture interface make it suitable for benchtop deployment without requiring dedicated floor space or structural anchoring.
Key Features
- Electromechanical actuation with adjustable crosshead speed (10–180 mm/min), digitally controlled via integrated potentiometer or optional external analog/digital input
- High-precision trapezoidal lead screw drive ensuring repeatable positioning accuracy (±0.02 mm typical over full stroke)
- Rigid single-column aluminum alloy frame with reinforced base plate, optimized for vibration damping and long-term dimensional stability
- Standardized M6 threaded mounting interface at upper and lower crossheads for rapid interchange of tensile grips, compression platens, peel fixtures, and custom adapters
- Integrated overload protection circuitry and mechanical end-stop limit switches compliant with IEC 61800-5-1 safety standards for drive systems
- Low acoustic emission (<55 dB(A) at 1 m distance) enabling operation in shared laboratory environments without acoustic isolation
Sample Compatibility & Compliance
The DV-500E accommodates specimens up to 200 mm in active travel length and supports standardized test geometries including dog-bone tensile bars (ASTM D638 Type I–V), film strips (ISO 527), wire segments, elastomeric cords, and miniature electronic connectors (e.g., USB-C, micro-FPC, PCB edge connectors). Fixture compatibility extends to pneumatic, wedge-action, and self-tightening jaw designs rated for ≤500 N service load. All mechanical components conform to RoHS Directive 2011/65/EU. When paired with calibrated load cells traceable to NIM (National Institute of Metrology, China) or NIST-equivalent national standards, the system supports GLP-compliant data generation under ISO/IEC 17025:2017 requirements for testing laboratories.
Software & Data Management
The DV-500E operates in standalone mode using front-panel controls or integrates with third-party data acquisition software via RS-232 or USB-to-serial interface (standard). Raw analog output (±10 V) corresponds linearly to applied load and displacement signals, enabling synchronization with external DAQ systems such as National Instruments LabVIEW or MATLAB Data Acquisition Toolbox. While the base configuration does not include proprietary analysis software, it supports CSV export of time-stamped load-displacement datasets compatible with common post-processing tools (e.g., OriginLab, Python pandas, Excel). Audit trail functionality—including operator ID, test date/time, calibration certificate expiry, and fixture ID—is implementable via external LIMS integration under FDA 21 CFR Part 11-compliant environments when paired with validated software layers.
Applications
- Insertion/extraction force characterization of electrical connectors and MEMS packaging interfaces
- Tensile strength and elongation-at-break measurement of polymer films, adhesives, and biomedical tubing
- Compression modulus evaluation of foams, gels, and soft tissue simulants
- Peel resistance testing of laminated structures (e.g., medical pouch seals, flexible electronics substrates)
- Proof-load verification of miniature springs, latches, and micro-mechanical assemblies
- Educational demonstrations of stress–strain behavior in undergraduate materials science curricula
FAQ
What load cell options are compatible with the DV-500E?
The system accepts standard 3-wire or 4-wire strain-gauge-based load cells with ±5 V or ±10 V analog output, rated from 5 N to 500 N full scale. Calibration certificates must be provided by an ILAC-MRA accredited laboratory.
Can the DV-500E perform cyclic loading tests?
No—the DV-500E is configured for monotonic quasi-static testing only. Cyclic or fatigue testing requires a servo-hydraulic or electrodynamic system with closed-loop waveform control capability.
Is firmware upgrade support available?
Firmware updates are distributed annually via secure download portal to authorized distributors; version history and release notes comply with IEC 62304 Class B software lifecycle requirements.
Does the machine meet CE marking requirements?
Yes—the DV-500E carries CE marking under the Machinery Directive 2006/42/EC and EMC Directive 2014/30/EU, with technical documentation archived per Annex VII.
What is the recommended recalibration interval?
Annual recalibration is advised under ISO/IEC 17025:2017 Clause 7.7.1, or after any impact event exceeding 120% of maximum rated load.
