CEMB USA TA18S - Manual

Acceleration transducer mod. TA18S
FUNCTIONING
The TA18S transducer picks up seismically the absolute vibrations of the machine by being fitted directly to
the supports of the vibrating part; it supplies an output signal directly proportional to the vibration of the point
to which it is fastened. Such signal should subsequently be processed by one of the measuring channel of a
CEMB serial “T” or “N” processing unit.

ASSEMBLY
Make a threaded hole on the support to be tested. The surface where the transducer rests must be perfectly
smooth and flat. Is is advised to provide a film of silicon between the resting surface and the sensor.
NOTE : avoid hitting violently the transducer housing, the closure couple must be 2,7÷6,8 Nm.
MAINTENANCE
