Type MC 75.2 Multifunction process calibrators for electrical signals

The SIKA multifunction process calibrators were developed to make your calibration and maintenance tasks easier and more flexible. Thanks to their versatile functions, different test sequences can be completed in one pass without changing instruments, which saves time. SIKA multifunction process calibrators combine the tasks of a wide variety of individual instruments in one.

They can be found in various main application areas, including service, maintenance and repair, quality assurance, testing laboratories and research, measurement and control technology, process industry, energy supply, machine and apparatus engineering, and many other areas.

If a periodic call-up is required, an automatic program run is generated. The signal type, duration and value are defined here. A possibly desired start delay, the number of repetitions and a continuous, linear ascending or descending course can also be specified individually.

Signal values that are needed again and again are stored in the simulator in a fixed or flexible manner and can be called up quickly at the touch of a button. If a discontinuous course with changing signal values is to be generated, the synthesizer function can help. Here, previously programmed, changing signal heights are output at the simulator's output. This makes it easy to define a wide variety of staircases, ramps or synthesizer values and call them up one after the other, which helps to fulfill the test task.

In order to achieve exact measurement results, the characteristic measurement properties and deviations of a probe should be taken into account if they are available in the form of a calibration certificate. By means of offset programming, the simulator input can be shifted linearly and thus approximated to the existing measurement curve of the probe. This one-point adjustment is the simplest and best known way to improve the measurement results. If higher demands are made on the measuring accuracy, a multi-point adjustment is the best option. Here, the input is ideally adapted to the real sensor curve by means of four linearization points, and thus linearity errors are compensated. Up to five different adjustment sets can be stored directly and called up easily.

In measurement technology, ideal, linear characteristic curves are often the basis. In the real world, however, various offset, slope, linearity or hysteresis errors in sensors, transmitters, converters, etc. very often result in non-linear curves. In order to measure or generate such non-linear characteristics without errors, it is possible to adapt the measurement input or signal output user-defined with up to ten interpolation points. The unit associated with the value is freely editable.
