Measuring device to be placed on supporting surfaces of objects being measured
A measuring device is provided which, in order to measure measured variables of an object being measured, can be placed on a surface of the object being measured. The surface supports the measuring device. The measuring device comprises at least three projecting contact surfaces, the center points of which are distributed substantially uniformly along a circle. The projecting contact surfaces, when the measuring device is placed on the surface of an object being measured, lie against the surface and are supported by the surface. A first of the contact surfaces comprises a temperature sensor for measuring the surface temperature of the object being measured, while a second and a third of the contact surfaces are provided to measure respective other measured variables.
1. A measuring device which, in order to measure measured variables of an object being measured, can be placed on a surface of the object being measured, which surface supports the measuring device, said measuring device comprising at least three projecting contact surfaces, the center points of which are distributed substantially uniformly along a circle and which, when the measuring device is placed on the surface of an object being measured, lie against said surface and are supported by the surface, wherein a first of the contact surfaces comprises a temperature sensor for measuring the surface temperature of the object being measured, while a second and a third of the contact surfaces are provided to measure respective other measured variables.
2. The measuring device as claimed in claim 1 , in which the second contact surface is a part of a first vibrometer for measuring oscillations of the object being measured.
3. The measuring device as claimed in claim 2 , in which the first vibrometer has a MEMS component, which is provided or designed to determine a direction with respect to the perpendicular towards the center of the Earth.
4. The measuring device as claimed in claim 2 , in which the third contact surface is part of a second vibrometer for measuring oscillations of the object being measured which are of higher frequency than the oscillations of the object being measured that are measured by the first vibrometer.
5. The measuring device as claimed in claim 4 , in which the first vibrometer and/or the second vibrometer has a MEMS component, which is provided or designed to determine a direction with respect to the perpendicular towards the center of the Earth.
6. The measuring device as claimed in claim 2 , in which each of the contact surfaces is assigned at least one magnet, wherein the measuring device can be fixed to the surface of the object being measured by means of magnetic forces exerted by the magnets.
7. The measuring device as claimed in claim 6 , in which at least one of the magnets is designed to be movable.
8. The measuring device as claimed in claim 2 , which has at least one processor and/or at least one data memory and/or at least one interface for data transmission and/or at least one energy source and/or at least one connection for an energy source.
9. The measuring device as claimed in claim 8 , in which the at least one interface is provided for cable-bound or wire-free data transmission.
