Description

The invention relates to a distance gauge, in particular a track gauge, for monitoring predetermined Distances from rails od. The like. Containing at least two mutually displaceable parts that are attached to its two outer ends facing away from each other with the rails or the like are equipped, wherein a compression spring is provided which the two can be displaced against each other Tends to push parts apart.

With known distance gauges of this type (Austrian Patent 6907, French patent 679 655, USA patent 2 286 456) acts the one of the two parts with a relative displacement on a pointer, which is on a the other part arranged scale moves. With such an arrangement, the reading of the Measured value, which is indicated by the pointer on the scale, cause difficulties, in particular when the distance gauge is used in the dark. In addition, there is no direct one It is possible to display whether the measured actual distance exceeds a specified target value or falls below. Rather, a measured value must be read off and then with the specified value Target value to be compared.

The invention is based on the object of creating a spacing gauge of the type mentioned at the beginning, which offers the possibility even under difficult conditions, for example in the dark, to display impermissible deviations of a measured actual value from a specified target value.

To solve this problem, the distance gauge according to the invention is characterized in that both one and the other of the two mutually displaceable parts are equipped with at least one contact carrier each, which are assigned to one another and close or open at least one circuit serving to output a signal as soon as the monitored distance exceeds or falls below a certain level.
It is already known (German patent specification 937 921) to close an associated circuit when measuring distances. Here, however, it is a matter of the absolute determination of small displacement paths, such as the axial gap of turbines, for example, the circuit being used for a calibration to be carried out with each measurement process. The actual transmission of measured values from a permanently installed button to a measured value receiver takes place mechanically.
According to the invention, on the other hand, a distance gauge is created which is suitable for measuring any distances and offers the possibility of determining whether the measured distance exceeds a predetermined target value without directly reading the measured value.

As a result, the green lamp 13, for example, receives power and indicates that the actual distance is too small.
