Application description

ProLine specifically targets standardized testing of materials and components, making operation of these testing machines notably simple and compact.

Standardized tests on components are diverse: Examples include testing plug and spring contacts in the electrical industry, checking joining and pressing procedures on precision engineered components and ring stiffness tests on reel cores and pipe sections.

In the packaging and food industries testing includes stackability tests on plastic containers and cardboard boxes, open-and-close tests on snap-on lids, pull-off tests on can lids, tear-growth and adhesion tests on plastic films and hoses and pull-off tests on carrying-handles.

Key Advantages and Features

Integrated safety in accordance with the EC Machinery Directive

The statutory safety requirements of the EC Machinery Directive are implemented in all ZwickRoell machines, while an EC Declaration of Conformity accompanies every machine. The most state-of-the-art safety technology and proven industrial components that comply with the highest safety and industrial standards (IEC 60947 etc.) are used. The highest degree of safety for user and testing system is guaranteed.

Powerful drives

  • Extremely low minimum speeds can be set, combined with high speed-stability. The drive also delivers high crosshead-travel resolution. This is important in cases such as component tests with especially demanding travel-precision requirements, or tests on specimens with high stiffness and short travel.
  • The high test-speed range can be used without restriction. In addition, test loads up to 110% of machine nominal load are permissible to compensate for heavy combinations of test fixtures, accessories etc.
  • Faster return speeds mean reduced cycle times and increased test throughput. The motor employs zero-maintenance AC technology.

High stiffness and precise crosshead guidance

Two steel columns provide highly accurate guidance for ProLine's moving crosshead. The stiff load-frame profile and generous connecting surfaces reduce the inclination angle of the crosshead under load, enabling very precise alignment and application of force to the specimen. This is advantageous for flexure tests, compression tests, precision tests on components etc.

Safety for the Entire Testing System

The two-channel safety circuit, including Emergency STOP, crosshead limit stop switch and interlinked accessories, Drive OFF switch and motor brake function, together with the operation mode switch, ensure enhanced safety during setup. The CE-compliant electrically interlocked safety device prevents interference with the machine during the test.

Exclusively at ZwickRoell: Xforce Load Cells

Patented Xforce load cells are developed and manufactured by ZwickRoell, and offer outstanding accuracy and high resistance to parasitic influences. Parasitic influences such as temperature and transverse forces have significantly less impact on test results than other comparable sensors. Xforce load cells are also very robust and more resistant to factors such as transverse forces during compression and flexure tests.

Mechanical Modularity

Mechanical modularity enables the testing system to be expanded by the wide range of ZwickRoell test fixtures and specimen grips or with customized devices. This is where the highly adaptable, play-free plug and T-slot system comes into its own, backed by a wide variety of crosshead mount options. Specimen grips and test tools can be changed whenever required, enabling a wide range of tests to be performed with the same testing machine and allowing rapid, highly flexible adaptation to the current testing situation.

Short delivery times

The very short delivery time for ProLine materials testing machines - 2 weeks - makes it possible to get started with testing quickly and without losing valuable time.

Powerful, Innovative testControl II Electronics

Innovative testControl II Machine Electronics

All of ZwickRoell's materials testing machines are equipped with the powerful testControl II measurement and control electronics, offering the ideal basis for precise, reproducible test results.

  • The electronics are installed vertically on the load frame to prevent liquids and from entering the unit and contact with conductive particles.
  • The high-quality finish protects testControl II from external influences. The components used are highly durable.

testControl II control technology and testXpert II testing software–a powerful combination

testXpert III testing software and testControl II machine electronics are perfectly matched, ensuring safe and efficient operation of the testing system. testXpert III provides the optimal solution for any testing requirement.

Flexibility Through Modularity

testControl II has six flexible time-synchronized slots, allowing multiple sensors to be used simultaneously and monitored and safeguarded regardless of use.

  • As an example, an extensometer and a transverse strain extensometer can be used in addition to the load cell.
  • If the testing system is equipped with several load cells or additional sensors, these can all remain plugged in. All sensors which are plugged in will then automatically be protected against overloads.

Machine compliance correction

The high-quality drive technology plus online correction of machine compliance enable very high travel-measurement and positioning accuracy. testXpert III automatically determines the optimum curve, ensuring maximum possible accuracy for travel measurement and positioning via the crosshead displacement transducer.

High Data Transmission Rate

Synchronous 500 Hz measured-value acquisition-rate delivers fast measurement with maximum reproducibility (regardless of number of measurement channels). The measured-value acquisition-rate can optionally be increased to 2000 Hz. The high data transmission rate enables fast measurement with maximum reproducibility. This is highly advantageous for high-speed tests, short brittle-fracture events and in tear-growth, adhesion and peel tests.

System Monitoring

testControl II system monitoring provides the user/laboratory manager with detailed information on the current status and level of utilization of the testing equipment. This enables further increases in testing equipment availability and greatly simplifies maintenance planning and spares/replacement procurement.

Fast, Adaptive Drive Controller

The high drive control frequency of 1000 Hz delivers fast, precise force and strain control. Benefits include enabling components to be loaded very quickly and accurately with a predetermined force.

Maximum Accuracy

High (24-bit) resolution and A/D converter with 400 kHz sampling rate for maximum measured-value accuracy combined with large measurement range. As an example, even the smallest force changes on the specimen can still be recorded and displayed accurately.

Innovative Interfaces

The innovative EtherCat® interface is incorporated as standard. The time-synchronized real-time Ethernet field bus system ensures future-proof integration of sensors and power units.

Eco Mode

testControl II electronics switch automatically to eco-mode when not in use, saving energy.

Ergonomic Remote Control with Display

Tests can be performed entirely via the remote control, independent of the PC. All important information is shown on the display. Machine operation is therefore more ergonomic and effective. The rocker-switch with integrated dial makes positioning fast yet highly accurate.
