Probe Installation; Gap Indications During Mounting - GE Bently Nevada 7200 Series Installation Manual

2.4 PROBE INSTALLATION

Perform the following procedure to assure proper probe installation. The observed surface must
remain motionless while gapping the probe. The probe can be gapped mechanically or electrically.
Use either steps a and b or steps a and c.
a. Before installing the probe into its mounting hole, ensure the tapped hole is free of foreign
material. If necessary, use an appropriate tap to clean the threads. Before the probe is threaded,
disconnect the probe integral cable from the Proximitor or make sure it is free to turn to prevent
twisting the lead.
b. The probe can be gapped mechanically. Thread it into the mounting and use a nonmetallic
feeler gauge to set the gap. A nonmetallic feeler gauge must be used to prevent scratching of
the probe tip or the observed surface.
