Product Overview

The KR‑207A servo‑electromechanical horizontal universal tester merges precision mechanical transmission and digital electronic measurement technology. It delivers highly repeatable control of test load and moving speed, with excellent accuracy for force and displacement acquisition. It supports constant‑velocity loading and constant‑velocity displacement test modes. Thanks to its long horizontal test stroke, this bench‑frame device excels for lengthy specimens that cannot be easily mounted on vertical testers. Unit capacities range from 2 ton up to 20 ton, for both metallic and non‑metallic material quality‑control and R&D work, and complies with GB/T 16491‑1996 universal tester standards.

This system completes tensile, compression, bending, shear, peel, tear and two‑point extension evaluations for rubber, plastics, cables, safety‑belt webbing, leather, composite sheets, waterproof membranes, copper‑steel profiles, spring steel, stainless‑steel strips and non‑ferrous metal wire. It is widely deployed across manufacturing workshops, QC laboratories, university material‑science departments and third‑party inspection‑arbitration institutions.

Core Product Competitive Advantages

1. High‑Stiffness Long‑Stroke Horizontal Mechanical Frame Heavy‑duty horizontal bed‑type structure provides an extra‑long effective tensile stroke, custom‑extendable for extra‑long samples. Equipped with adjustable leveling feet plus auxiliary moving casters for convenient on‑site repositioning. AC servo drive enables both jog fine‑tuning and fast cross‑head return after test completion.
2. High‑Precision Measurement Acquisition System High‑resolution photoelectric encoder captures displacement values. Embedded micro‑controller integrates measurement, control, arithmetic and data‑storage functions. Force sensor delivers constant resolution of 1/200 000 of full‑scale. An optional external extensometer can be fitted for accurate elongation and elastic‑modulus calculation.
3. Feature‑Rich Windows‑Based Test Software Pre‑loaded standard test templates cover GB, ASTM, DIN, JIS, BS and other international norms. Operators input product‑specification parameters once and reuse them repeatedly. Multiple‑format editable report outputs include native Excel export. Force‑displacement, force‑time, stress‑strain and two‑point‑extension curves render in real‑time. Post‑test curve zoom‑in and overlay support advanced comparative analysis. The program auto‑computes tensile strength, yield‑point values, breaking elongation, modulus, peel‑force statistics and total absorbed‑energy metrics. Force‑and‑length units are fully convertible: N, kg, lb, ton, mm, cm, inch. Test datasets can be saved locally to any disk partition for later review.
4. Multi‑Level Electronic Safety Interlock Built‑in electronic travel limit stops prevent cross‑head over‑run. When load exceeds 110 % of rated sensor capacity, automatic overload‑protection triggers to halt motion and protect the precision load‑cell. Users can select manual‑initiated or automatic home‑return after each completed test cycle.
5. Flexible Fixture Expandability Standard delivery includes primary tensile‑grip assembly. Additional custom‑made jigs for peel, bending, shear and special‑shaped work‑pieces are available to satisfy diversified test‑sample geometries. Multiple interchangeable load‑cells can be fitted to widen the effective measuring scope.

Standard Complete Test Operating Workflow

1. Equipment Check‑Up & Program Setup Power‑on host and computer; launch the dedicated test software. Open or create test procedure matching material standard; define stop‑conditions, report‑template and unit‑settings.
2. Specimen Mounting & Alignment Operate jog‑mode to adjust cross‑head position; secure specimen firmly inside corresponding fixture, ensure good axial alignment to eliminate eccentric‑load influence. Fit extensometer (if required) onto specimen gauge‑length section.
3. Pre‑Test Zero‑Calibration Carry‑out force‑value and displacement zero‑reset to clear initial mechanical offset.
4. Automatic Test Execution Initiate test sequence. Servo‑driven cross‑head moves at preset velocity; system continuously records force, displacement and deformation while plotting real‑time test curves.
5. Post‑Test Data Review & Report Export After specimen fracture or reaching termination criteria, test stops automatically. Review characteristic‑point data, zoom and compare curves; export datasets to Excel or print formal inspection reports.
6. Machine Shutdown Procedure Cross‑head returns to home position; remove tested specimen and clean fixture surfaces. Close software and cut main power supply.
