Description

Device for registering analog measured quantities

The innovation relates to a device for registering one or more analogue kebab sizes on one tape-shaped recording media which can be displaced in the longitudinal direction, e.g. paper strips, by means of one or more writing elements adjustable over the width of the recording medium as a function of the measured values.

In such devices it is necessary to control the deflection caused by the actual measuring mechanism of the (each) writing organ to adapt to the scale division of the recording medium in order to avoid incorrect evaluations. If such an adaptation is carried out for two specified measured values (two-point calibration), then it is not yet guaranteed that there is also full adaptation for the other measured values. This difficulty arises especially when recording measured quantities on a non-linear, e.g. logarithmic or quadratic, scale on. Here one generally has to make do with conversion tables or reading rulers, whereby the evaluation is made much more difficult.

The innovation is based on the task of calibrating the recording medium in devices of the type mentioned at the beginning to simplify. According to the innovation, the3 is thereby achieves that for calibration the traces of writing further, over the width of the recording medium on predetermined adjustable writing organs are used, which are preferred

weisο crawls on one to the direction of movement of the recording medium arranged bracket are mounted longitudinally displaceable.

The advantage that can be achieved with the innovation is, in particular, that any, e.g. non-linear, scale divisions at the same time as the measured variable to be recorded on a scale which preferably does not have a predetermined scale and thus inexpensive recording media by means of a number of further ones corresponding to the graduation marks Writing organs can be recorded in a simple manner. An adaptation of characteristic values of the measuring units to a predetermined graduation for the purpose of a two-point drawing is not applicable here. Furthermore, by Eigenfeh-5 Deviations in the actual deflections caused by the measuring mechanisms of the target deflections of the registering writing organs through a corresponding setting of the Graduated writing organs can be compensated.

The innovation is described below with the aid of a preferred exemplary embodiment shown schematically in the drawing closer elucidates.

With 10 and 11 a supply roll and a deflection roll for the recording medium 5 are indicated. The drive of 5 takes place e.g. by means of an individual toothed roller, not shown, engaging in the peripheral perforation 12, which are especially mounted on the axis of the deflection roller 11 can.

For calibrating the recording medium 5 with regard to the measured value amplitudes further writing organs 13 are mounted on a bracket 14 so as to be longitudinally displaceable, the zv / eckierterweiae is arranged perpendicular to the direction of movement 6 of the recording medium 5. When recording the desired Eichwertc is preferably proceeded in such a way that these enter the measuring mechanism 1 and the individual writing elements one after the other 13 are each adjusted to the deflections A of the scrub organ 4 obtained in this way. Those evoked by 13 Writing tracks 15, which are recorded simultaneously with the writing track 7, then form calibration lines for precise reading of the measured values represented by the deflections A.

The innovation is of course on all possible methods or systems of measured value recording with tape-shaped Recording media can be used, e.g. on paper scribers with writing organs in the form of colored pencils, ballpoint pens, fountain pens, nibs, etc., on the various scoring methods using Y-axis paper strips and, among other things, on the various clip systems. The writing organs for recording the calibration lines are expediently of the same type as the writing organs assigned to the measured values. On too
