testControl II – the Innovative Electronics

Powerful, innovative measurement and control technology.

testControl II measurement and control electronics provide the ideal basis for precise, reproducible test results. As well as setting new standards in safety technology, efficiency and quality, testControl II is laying down a benchmark for drive technology.

Advantages & features

High measuring accuracy and reproducibility

Maximum accuracy
The smallest force changes on the specimen are quickly and accurately recorded and displayed. The A/D converter guarantees high measured-value accuracy over a wide measurement range with sampling rates of 400 kHz and 24 bit resolution.

High data transmission rate
Each travel and force peak is acquired with high resolution and recorded synchronously at 500 Hz on all measuring channels. Optionally, the measured value acquisition rate can be expanded to 2,000 Hz. The high data transmission rate enables fast measurement with the highest degree of reproducibility. This is highly advantageous for quick tests, short, brittle fracture events and in tear-growth, adhesion and peel tests.

Time-Synchronous Signal Processing
Time-synchronous acquisition of measured values from all sensors connected to plug-in slots takes place at the fast system-frequency, as does data transmission to ZwickRoell testing software. This ensures high test-result reproducibility regardless of the sensors in use or the test sequence; for example force and travel signal synchronicity is maintained, even with strongly differing test speeds.

Machine Compliance Correction

Real-time correction via the corrected channel directly in the testControl II electronics, regardless of test speed and duration!
Control and positioning directly to the corrected channel.
Ideal for tests for which direct-measurement extensometers cannot be used.

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

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.

Powerful Drives and Drive Controllers

Fast, adaptive drive controller
The high drive control frequency of 1,000 Hz delivers fast, precise force and strain control. Benefits include enabling components to be loaded very quickly and accurately with a predetermined force.

Strain Rate Control
The AllroundLine drive technology’s excellent constant-velocity characteristics and interaction with the sensor technology and adaptive control make it ideal for demanding strain-rate control (e.g. ISO 6892-1, Method A1).

Controller Setup
Special controller set-up for testing situations with demanding control requirements. For example, if the force sensor is located on the fixed crosshead in force-controlled tests, the controller can simply be switched in the software.

Powerful Drives
Powerful drives allow cyclic tests to be performed at maximum speed up to nominal load - with no waiting time between tests. AllroundLine and ProLine use maintenance-free AC drives.

Flexibility through modularity

Flexibility Through Modularity

For 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 plugged-in sensors are automatically protected against overloads.

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.

Gigabit Ethernet Interface
The Gigabit Ethernet interface (a proven industry standard) for the testing machine computer enables very high data throughput.

Use in dynamic testing

testControl II measurement and control electronics represent a universal controller for various drives used in materials testing.

The version developed for servo-hydraulic testing machines allows control of hydraulic linear or torsion testing actuators, used free-standing or in a testing machine.

The controller can be used for static, quasi-static, oscillating and dynamic tests on materials, components and complete structures.

The double axis controller is used for combined tension and torsion axis actuators.

testControll II Xtension

Plug & play - quick and easy to use with standardized operation in ZwickRoell Roel testing software.
Fast switching between various testing situations with different sensor systems, while your sensors remain connected.
Money-saving mobile use on different testing machines.
All testControl II Xtension channels can be used for any calculations.
testControl II Xtension's sensors can be used for force / strain control.
Easy retrofitting whenever you need extra sensors.
With the second testControl II Xtension even applications with an unusually large number of sensors are possible.

Ergonomic remote control with display

You can control the testing system with the remote control:

Start or stop a test
Approach the initial position LE
open or close automatically controlled specimen grips
specify self-defined functions

You can drive the crosshead of the testing system via the rocker switch.
