Combined sealing plug and vibration sensor for sealing a drive sump or oil reservoir and for providing vibration measurements, whereby the sensor is mounted in the head of the sealing plug in a tapped hole

摘要

Sealing screw (1) for sealing a drive sump has an outer thread (6) for insertion in a threaded hole (8) to provide a leak-tight seal. The sealing screw has a second threaded hole (2) with a counter sink into which a sensor is inserted and tightened. The sensor is removed by unscrewing it. Typically the sensor is a vibration sensor capable of measuring frequencies between 0 Hz and 10 MHz. The invention also relates to a series of inventive sealing screws, suitable for use in different diameter threaded holes.
