Abstract

In a pressure sleeve in particular a vibration pickup, an abutment surface is formed as a circumferential ring at a location radially spaced from a central point. Therefore, the pressure sleeve can be fully pressed against the structure to be monitored by a mounting screw. Therefore a sensor provided with the pressure sleeve can approximately linearily extending and disturbance measuring signals.
