The GE / Bently Nevada 330106-05-30-10-02-05 is an 8 mm reverse mount proximity probe from the 3300 XL series, engineered for machinery vibration monitoring and protection in industrial applications. This non-contacting transducer generates output voltage proportional to the distance between the probe tip and a conductive target surface, enabling simultaneous measurement of static position and dynamic vibration. The probe operates across a 2 mm (80 mils) linear range beginning approximately 0.25 mm (10 mils) from the target.
