Abstract

An accelerometer, consisting of a body having a threaded coaxial nipple for screwably securing the body to a mounting base having a connection for a signal transmission cable. The mounting base can be glued firmly or screwed to a measuring surface, and configured so that accelerometers may be mounted thereto and oriented in several axial directions. It is therefore possible to investigate several axis directions successively using one accelerometer. The object to be measured out can be provided with a large number of single- or multi-axis mounting bases, enabling the entire surface of an object to be measured stepwise in one or more axes, using one or only a few accelerometers. Furthermore the detachable connection between mounting base and accelerometer body facilitates occasional calibration of the accelerometer away from the particular measuring object.

Claims

1. An accelerometer comprising:

body having a threaded coaxial electrical nipple;

acceleration sensor in said body;

mounting base means having a thread electrical socket for receiving said electrical nipple to secure said body to a surface of said mounting base means; and

connecting socket in said mounting base means for connecting said electrical socket to a signal transmission cable.

2. An accelerometer according to claim 1 wherein said mounting base means includes a plurality of electrical sockets at a plurality of surfaces to mount a body in more than one axial directions.

3. An accelerometer according to claim 2, wherein said mounting base means has a cubic shape and said electrical sockets are at right angles to each other.

4. An accelerometer according to claim 1 including mounting means for mounting said mounting base means to an object at a mounting surface.

5. An accelerometer according to claim 4 including flutes on said mounting base means for receiving wrench.

6. An accelerometer according to claim 4 wherein said mounting means includes holes in said mounting base means and screws in said holes.

7. An accelerometer according to claim 4 wherein said mounting means is glue.

8. An accelerometer according to claim 1 wherein said body has a cylindrical shape and said mounting base means has at least one mounting hole for receiving said cylindrical shape of said body.

9. An accelerometer according to claim 8 wherein said mounting hole includes a preloaded slot.

10. An accelerometer according to claim 8 wherein said mounting base means includes a plurality of electrical sockets in a plurality of mounting holes in a plurality of surfaces.
