Abstract
A vibration meter having a pressure sleeve is proposed, in which the pressure sleeve (2, 22) may be mounted under pressure at a bottom surface (20) on a component causing vibrations, and the bottom surface (20) has a contour, prior to mounting, which runs radially inward in a concave manner. Furthermore, prior to mounting, the bearing surface (21) has a contour, which runs radially inward in a concave manner, the contour being dimensioned such that, after the mounting, at least one sensor arrangement (7, 5, 6, 8) lies substantially flat on the bearing surface (21) on the inside of the pressure sleeve (22).
Claims3
A vibration meter having a pressure sleeve, in which,
- using a base surface (20), the pressure sleeve (2, 22) may be mounted under pressure on a component causing vibrations, the bottom surface (20) having a contour, which runs radially inward in a concave manner prior to mounting and may be changed by the pressure in mounting, and having
- a sensor arrangement (7, 5, 6) and additional components (8, 9), the sensor arrangement supported at the outside of the pressure sleeve (2, 22) under an initial axial stress, on a bearing surface (21) of the pressure sleeve (2, 22) situated inside of and opposite to the bottom surface (20), wherein
- the contact area (21) has a contour, which runs radially inward in a convex manner prior to mounting and is dimensioned such that, after the mounting, at least the sensor arrangement (7, 5, 6, 8) lies essentially flat on the bearing area (21).
