Type EC 25 Multifunction process calibrators for electrical signals

SIKA multifunctional process calibrators were developed to simplify calibration and maintenance tasks and to make them flexible. Different test sequences can be carried out in one run without changing instruments, which saves time. While monofunction process calibrators are ideal when only one type of signal is required, SIKA multifunction process calibrators combine the functions of a wide range of individual instruments in one device.

The main areas of application are in service, maintenance and repair, quality assurance, test laboratories and research, measurement and control technology, the process industry, energy supply, mechanical and apparatus engineering and many other areas.

The backlit multifunction display provides a clear and unambiguous display of the input and output values as well as all settings made. There is a widespread keyboard-guided operation using rubber keys as well as a convenient, menu-guided operation using function keys, navigation cross and numeric keypad. These controls also make it very easy to display and activate more extensive functions.

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

Frequently required signal values can be stored in the simulator in a fixed or flexible manner and can be called up quickly at the touch of a button. The synthesizer function helps to generate discontinuous sequences with changing signal values by outputting previously programmed, changing signal levels at the simulator output.

In order to achieve exact measurement results, the characteristic measurement properties and deviations of a sensor should be taken into account during a measurement if they are available in the form of a calibration certificate. Offset programming enables the simulator input to be shifted linearly and an approximation to the existing measurement curve of the sensor to be made. Single-point adjustment is the simplest and best-known way of improving the measurement results. If higher demands are placed on the measuring accuracy, a multi-point adjustment is the best option. In this case, the input is ideally adapted to the real sensor curve by means of four linearization points and linearity errors are compensated. Up to five different calibration sets can be stored directly and called up easily.

Measurement technology is often based on ideal, linear characteristic curves, but in the real world, various offset, slope, linearity and
