The displacement sensors of series RC20 are used in applications with harsh environmental conditions, which require a robust linear transducer with long life span, high accuracy and guided push rod with measuring lengths from 10 to 300 mm. The linear potentiometers of the series RC20 are designed for applications with harsh environmental conditions. For mechanical coupling, the displacement sensors are available in three mounting versions: mounting brackets, ball joints or flange. The variant with ball joints compensates movements transversely to the push rod, so that non-linear movements can also be coupled simply and without stress. The mechanical detection of linear movement is done by a front guided push rod

The optimized industrial module in modern design for intuitive control of 6 degrees-of-freedom (6 DOF), by pushing, pulling, rotating, tilting of the ergonomically handle The SpaceMouse® Module is the ideal man-machine interface for controlling 3D movements in industrial applications - only with one hand! It is the ideal input device for teaching robots, moving cameras, measurement systems, drones etc. The module covers both rotation and translation movements due to the 6-axis sensor. Consequently, it may replace two conventional joysticks in many applications, and thus the SpaceMouse® Module increases the control capabilities of the operator, saves space in control panels, and reduces investment costs. Totally new control concepts and control panels can be realized, without need of extensive training of the operator.

Thanks to the True-Power-On function, any angle changes are registered even during a supply voltage interruption and the angle is reproduced exactly as an analogue signal as soon as the supply voltage is restored. The contactless sensor technology works on the basis of modern gradient-based magnetic field evaluation in processor-supported circuit design. This makes the multiturn encoder largely immune to external magnetic fields or changing ambient temperatures. In combination with the precision mechanics, the encoder shows its additional strength compared to magnetoresistive methods. The latter can have weaknesses in voltage-free measured value acquisition. Another special feature of the multi-turn sensor are the signal plateaus at the beginning and end of the range, which prevent sudden signal changes. The electrically effective rotation range of the encoder is 3600°, ex works.

If, in a highly sensitive control system, the amplification should, for example, be so arranged that the control circuit will be stable with the mean slope (gradient) of the sensor, then it is important to be aware of any variations there may be in that slope (Fig. 12a, Fig. 12b). If, at any point, the gradient is appreciably steeper than the mean gradient, then there will be a higher closed-loop gain in this position and this could lead to feedback oscillation. If, on the other hand, the gradient is less steep at some point than the mean gradient, then repeatability would be reduced and there would be less control accuracy. If we relate this type of local gradient variation gl to the mean gradient go of the potentiometer, then this criterion is independent of the potentiometer length and can be used for the direct comparision of various potentiometers.

Smoothness is a measure of the deviations from perfect regularity that appear in the output voltage of a potentiometer. This irregularity is measured over a specified travel increment, for example 1 %, and is expressed as a percentage of the applied voltage. For the measurement of smoothness, the VRCI definition calls for a bandpass filter to be used as a means of suppressing any linearity error and for the potentiometer to be operated with a load resistance (e.g. 100 . Rp). This method has certain disadvantages: a) The use of a filter causes both the absolute wiper velocity and any changes in such velocity to affect the smoothness values. Since the filter partly integrates and partly differntiates, the chart-recorded smoothness curve does not accurately indicate the variations in the output signal. b) The load applied to the potentiometer also contributes to error by causing variation in the contact resistance which is greatest with the wiper at the voltage application end and...

When, some 60 years ago conductive plastic potentiometers were first introduced onto the market, it was apparent that although the winding jumps which were a feature of wire-wound potentiometers had been overcome, absolute smoothness of the output voltage could not be achieved. Following some basic reserach by. h. Wormser 4, 5, 6 , the term "smoothness" was included in the standard issued by the Variable Resistive Compontents Institute (VRCI). Although this definition was adequate at that time it cannot serve as a system definition for many applications. This is because it is now possible to produce potentiometers with appreciably better smoothness and linearity values. For this reason, Novotechnik has sought over the past years to develop definitions better suited to the current state fo the art. The various methods used are discussed and evalutated below.

If there is axial misalignment (eccentricity) between the drive shaft and the shaft of a potentiometer used to sense angular, motion, this will cause a linearity error that increases as the coupling radius decreases in relation to the degree of eccentricity. The following equation determines the maximum relative error Fmax = E/Pi · rk where E = Eccentricity und rk = the coupling radius. It is only possible to take full advantage of the linearity or conformity of any rotationary sensor system, if coupling alignment errors (offset and angular misalignment) are avoided or at least reduced to a mimimum. This means that with highly accurate measurement systems, due allowance must be made for any coupling misalingment in accordance with the above equation.
