A system specially designed for high precision measurements of compression. With its high reduction ratio, this manually operated test stand is well suited for the measurement of small springs with low force levels. The displacement sensor gives a measurement of the flexion or height measured under load with a resolution of 5 µm. The test stand is equipped with a set of adjustable limit stops. The measurement display shows the force and the displacement simultaneously and plots the graph curve for the spring. These data can be exported via the RS232 output of the display unit. The parallelism of the lower plate can be adjusted to ensure correct seating for the spring. An accessory kit can be used to make measurements on tension springs.

With its Centor Dual force gauge, fixed plate and adjustable plate, this unit can be used to test high capacity tension and compression springs. The command automatically determines the origin of the displacements and then stops the machine at a predetermined flexion value to measure the height under load. It is also possible to measure flexion, and cycles can be programmed. The instrument has an RS232 to store the results on a computer. Additional sensors are available to provide high levels of precision for springs with low force levels. Ready to use system. Supplied with a Ø 4 in fixed plate.

It is a universal testing machine capable of carrying out tensile, compression, bending, and shearing fesfs. Operation is manual, semiautomatic, and automatic. The test instrument can be modularised taking into account that the structure can house 3 permanently installed load cells for compression tests, and 3 sets of tensile grips for tests, including at break. Our system uses several cards (for axis and cell reader control) that are connected via CanBus to enable displacements to position or force at a feedback speed of 1000 Hz. Load cell reads are effected ì,000 times per second. Minimum indexing is 1/32,700 (this can be increased by slowing down load cell reading).

Surge Protection Devices (SPD) are also known as Transient Voltage Surge Suppressors (TVSS). These devices can comprise a complex arrangement of varistors, transorb diodes and gas arresters. The function is to divert lightning surge energy away from electrical or electronic equipment. They are activated by the steep voltage impulse generated by a lightning strike and are designed to conduct tens of thousands of Amps in impulse energy. Typical impulse tests for SPD devices include energy absortion (8/20us or 10/350us), duty cycle (8/20us), Clamping voltage (8/20us) and Combination Wave Tests for devices connected in the AC power main.
EMC PARTNER offer a range of instruments from a few Amps up to 100,000 Amps.
All units offer a combination of impulses specific for particular devices whether they are disc varistors, SMD varistors, Gas Arresters or combinations of all.

Mechanical Components
The mechanical design of the test bed has to be matched to the very specific requirements of a powertrain test bed which can vary considerably.
With all-wheel vehicles, for instance, the different wheelbase has to be taken into account. The challenge for the mechanics therefore is that the dynamometers have to be adjustable. The AVL solution allows simple axle and track adjustment by manual (or as an option automatic) shifting of the DynoWheel machines.
All the other modular mechanical standard components are specified to the requirements of powertrain testing and comprehensively tried and tested.
The special mechanical configuration of OptimaTest Powertrain test bed is modular and open for future extensions.
The flexible mechanical configuration of the AVL solution gives users a test bed with multi-configuration capability. The highly dynamic all-wheel powertrain test bed can easily be reconfigured for testing vehicles with front and rear-wheel drive. Different tests can therefore be carried out on the same test bed which makes for enormous cost savings.
The versatility of the test bed with its multi-configuration capability guarantees operators higher productivity, saving time and money.

SOLAR300 carries out all the recommended tests to check the performances of single and three phase photovoltaic installations. SOLAR300 measures output DC power of the cells, output AC power of the inverter, solar radiation and temperature of the cells.
Measurement of AC and DC power requires the user to connect the instrument's inputs upstream (DC) and downstream the inverter. The values in single-phase installations or in three-phase installations, are acquired simultaneously. Usually the inverter and the photovoltaic cells could be far each other. To skip the use of long cables, which are very uncomfortable, SOLAR300 uses a remote measuring device, SOLAR-01, that acquires the following parameters: solar radiation, temperature of the cells and environmental temperature.
At the end of the recording, the values acquired by SOLAR-01 are transferred to the SOLAR300 through an USB connection. SOLAR300 also permits recording of each parameters, the voltage/current harmonic analysis and the voltage anomalies (sags, swells) detection. Thanks to its built-in memory and its compact flash driver a considerable volume of data can be stored for further analysis.
The innovative touch screen system of SOLAR300 makes the data analysis extremely easy. In addition, the management software Topview allows the user to create professional reports displaying the company trade mark, the user's data, the recording comments, etc.

Recent sales of Zwick’s electro-mechanical testing actuator have provided unique solutions for customers carrying out diverse mechanical testing. For example, in the automotive industry it has been used to test seat head rests, foams, steering columns, gearshifts, brake pedal assemblies, switches, connectors, and solenoids. In the medical industry components such as needles and bone have been successfully evaluated, whilst for sporting equipment the system has carried out tests on skis, and snowboards.
This wide variety of tests is possible due to a truly impressive specification, and a reliable testing system based on many core components from the Zwick Roell Group product portfolio. The EM Actuator is the obvious solution for many different and complex testing applications.
The electro-mechanical testing actuator is quite unique as it can be directly assembled, at any angle, into a production line and controlled via dedicated I/O control systems, or it can be used in stand-alone mode with a dedicated test stand. In addition it can be fitted to any standard Zwick universal test frame thereby adding an additional test axis for tests which require side loads All standard Zwick attachments can easily be attached.
