Reliability and flexibility were important factors during the development of the universal testing machine inspekt table. As in all products Hegewald & Peschke MPT GmbH uses only high-quality components. The material testing machines of the inspekt table series are designed for universal usage at medium load range. Customers can choose between a desktop and a stand-alone model. For the setup of different tests, two different hand panels are available. For instance, the panel type RMC 7 includes a load-position-display, which makes it possible to operate the machine without external PC. Typical fields of application of the inspekt table machines beyond general products and material quality control are incoming and outgoing goods departments and research and development material testing laboratories.
In spite of their small weight, load frames of the universal testing machine inspekt table are characterised by especially high bending stiffness. Additionally, the standard version offers possibilities to connect different kinds of accessories, like clamping tools, temperature chambers, or extensometers. The moving crosshead is driven by a servomotor and two free from play pre-stressed ball screw spindles. In order to protect the spindle units from excessive contamination, e.g. if the material testing machine is used in an industrial environment, a set of bellows can be employed optionally.
Reliable load measurement in the universal testing machine inspekt table is ensured at any time with the help of high-quality load cells. They are equipped with sensor plugs, which guarantee automatic detection of set-up and calibration parameters. The electronics allow for class 1 measuring accuracy according to DIN EN ISO 7500 in the range of 0.4 to 100% nominal load. As an option, it is even possible to get class 0.5 measuring accuracy.
Measuring and controlling system
The measuring and controlling system of the series inspekt table has been especially designed for the use in material testing machines. All elements of power supply, machine and motor control are stored in a tower box. A digital controller is responsible for the control of the machine and synchronous data acquisition. Communication with an external PC is established with a USB or LAN port.
Traceability of measured data
The controller allows for load-, position-, and extension-controlled tests. All testing machines are calibrated before delivery, so that customers receive a machine that is specific to their demands and ready for immediate use. The calibration data of all sensor devices are registered and stored in the sensor plugs of the load cells or extensometers. If the sensor devices are exchanged later, the controller can readout the respective data automatically.
Industrial safety devices
To ensure the protection of the operator at any time, the load frames of the inspekt table universal testing machine can be equipped with different safety devices. This includes, for example, a safety door, which is controlled by the testing software LabMaster. Moreover, the material testing machine inspekt table are equipped with overload protection for the load cells, an electronic and mechanic crosshead travel limitation and an internal check programme.
