Registering measuring device

The innovation relates to a recording measuring device containing: a device housing with a window containing a viewing window Front panel, a chassis housed in the device housing, which has a guide for a recording strip, a Drive for the recording strips and a writing mechanism for recording one or more measured variables on the Registration strips.

In conventional measuring devices of this type, the instantaneous value of the respectively registered measured variable is indicated by a pointer connected to the writing mechanism. In the case of a drop-bow recorder, for example, the resilient pointer deflected by a galvanometer is pressed onto the transparent recording strip and an ink ribbon arranged underneath, so that a point is printed on the recording strip. The pointer protrudes forward and plays with one angled end in front of a scale. The instantaneous value of the measured variable can then be read on this scale. It is also known to - * close several measuring points by means of a measuring point switch

to switch each other in cyclical order to the galvanometer and synchronously with the switching of the measuring points different Move ribbons under the pointer. This analog display of the measured variable is not precise enough for some purposes. she is difficult to read even from a distance.

The innovation is based on the task of designing a recording measuring device of the type defined at the outset so that the Instantaneous value of the respectively registered measured variable is displayed with high accuracy and visible from afar.

According to the innovation, this object is achieved in that above the guide for the registration strips a digital display device for digitally displaying the registered Measured variable is attached.

The digital display device allows a display of the measured variable with high accuracy, also from greater Distance is readable. The protruding angled pointer end and the scale can be omitted.

Another embodiment of the innovation is the subject of claim 2.

An embodiment of the innovation is explained in more detail below with reference to the associated drawing, which shows in perspective a recording measuring device designed according to the innovation.

The measuring device contains a device housing 10 with a front plate 14 containing a viewing window 12 in the device housing A chassis 16 is accommodated, which has a guide 18 for a recording strip 2O. The recording strip 2O is driven by a drive (not shown). Sitting in the chassis

furthermore a writing mechanism for recording one or more measured quantities. It can be one act as a common multi-channel strap writer.

Above the guide 18 for r'en registration strips a digital display device 22 is attached for the digital display of the respectively registered measured variable. In addition to the digital display device 22 for the measured variable, a further display device 24 is attached, which synchronously can be switched with the measuring point switchover.
