Transducer with quick connector, terminal
For systematic shock pulse monitoring, the installation of shock pulse adapters is recommended.
Adapters are solid metal bolts of different length and thread sizes, tuned for correct signal
transmission. They are installed in threaded, countersunk mounting holes on the bearing housings.
Glue-on adapters are available.
To attach the transducer with quick connector, press it against the adapter and twist clockwise.
Twist counter-clockwise to remove it.
Adapter surfaces must be clean and plane. Use an adapter cap to protect them.
A permanently installed transducer and a measuring terminal (BNC or TNC connector) are used
when the bearing cannot be reached directly. Use a measuring cable to connect instrument and
terminal.
Check that installed transducers and adapters are properly mounted (see the instruction on SPM
installations) and in good condition. You cannot expect a useful signal by attaching the quick
connect transducer to a rusty lump of metal, or from a transducer that is rolling on the floor on the
other side of a partition.
