[0025] FIG. 1 shows a first embodiment of the invention, for example for registering unauthorized opening of the casing of an electrical device. Reference numerals 1 and 2 in FIG. 1 designate two parts that are movable relative to one another and which are connected to housing parts (such as housing doors and chassis), not shown in detail, of the electrical installation to be monitored. An electromechanical recording device is indicated overall with the reference number 3 . The recording device 3 comprises a monitoring chamber 4, a plurality of monitoring bodies 7, a sensor device 16 and transmission elements explained in detail below, which transmit the positional changes of the parts 1, 2 relative to each other to the arrangement On the arrangement of the monitoring bodies 7 in the monitoring room 4 . In the exemplary embodiment shown, the monitoring chamber 4 is formed by a first and a second annular cylinder 5 , 12 . Each annular cylinder 5, 12 is closed on one end face ...

Abstract

A device for detecting a change in position between two parts movable relative to each other, comprising: at least one electromechanical recording device, wherein said recording device has: a. monitoring of operations that are shielded from outside chamber, b. a plurality of monitoring bodies arranged in said monitoring chamber, wherein said plurality of monitoring bodies consists of at least two parts and these parts differ in physical parameters, c. transmission elements, said transmission elements will The change in positioning causes the monitoring body to switch from the first monitoring arrangement to the second monitoring arrangement when resetting to the initial state; a sensor device having a sensor that generates a sensor signal that is associated with the One corresponds to a physical parameter of the monitoring body of each sensor in the second monitoring arrangement and each sensor signal is supplied to the evaluation unit.

Description

technical field [0001] The invention relates to a device for detecting a change in position between two parts that are movable relative to one another. Background technique [0002] It is known that measuring instruments for recording energy consumption, such as electricity, water or gas meters, are protected by lead seals. Valuable transport containers, containers and rooms, which are inaccessible to unauthorized personnel, are sealed with seals or seals such as self-adhesive sealing labels, so-called "VOID-Labels". Seals are often made of a wire formed by a bond that passes through the hole in the object to be protected and whose intersection is surrounded by the embossing of the lead. A break in the seal can only be found on site. If the seal is broken and Replaced by a forged seal, or if a previously broken seal is reclosed by skilful handling and suitable tools, such unauthorized interference cannot be detected with certainty. [0003] In order to determine whether th...
