resolution of at least 100.000 points sufficient slots is necessary.As opposed to the past where measured values had to beread in one after the other, all measured values of the sensors connected to the measurement, control and regulation electronics can be recorded available forthe user so that all sensors necessary for a test can be collected.The synchronously totoday’s technological status. Nowadays additional runtime corrections are made between the different preparation methods to make sure that all measured values that are transmitted to the evaluation software are determined at exactly the same moment in time.The MCRE must always make online transmission of all test data recordedduring the test

Tasks of measurement, control and regualtionelectronics in test technology

Taking the example of calibrating a strain gauge load cell manufacturer to grade 1 within the measurement range limits of 0,2% - 100% of the nominal load to DIN EN 10002-3, a to the software for further processing is avery important requirement for enabling testing rapidly and to test standards. This is the only way that an event controlled influence on the test sequence can be made. Measurement, control and regulation electronics (MCRE) takes over a central role in a test system. Everything, from preparation of the physical measurement signals, for final processing via appropriate programs, via control of the test sequence up to drive system regulation, takes place entirely automatically and in real time. The increasing functionalities of modern micro-electronics allow more and more functions in a test system to be carried out direct on the electronics. This makes operation of such a system increasingly simpler.The use of standard electronics, e.g. to SPS or PC basis,doesn’ offer, amongst others, the necessary accuracies or resolutions to be able to offer a certain modular system solution.

Measure

The target of materials testing is to determine physical properties of materials or components via single-axis or multi-axis loading. For this purpose, different sensor technologies are attached to the object to be tested. Different methods are available for this. For example, measurement of analogue voltages on strain gauges forforce measurement, measurement of incremental signals(square wave or sine) from glass scales for travel measurement. These signals are converted to digital signals with corresponding resolution by the electronics.
