The GE / Bently Nevada 330101-00-40-05-02-05 is an 8 mm proximity probe from the 3300 XL Series engineered for differential displacement measurement in machinery vibration and position monitoring. The unarmored probe features a 3/8-24 UNF thread and delivers analog output proportional to the gap between the probe tip and conductive target surface. Constructed from AISI 303/304 stainless steel with a polyphenylene sulfide tip, it operates across -51°C to +177°C (-60°F to +351°F) with extended temperature capability to 260°C (500°F) for lead and connector. The system achieves ±0.076 mm (±3 mils) accuracy over an 80 mil linear range in standard 5-meter configurations when calibrated to AISI 4140 steel targets.
