Configured for eddy-current displacement measurement in machinery protection systems, the Bently Nevada 330104-00-05-10-02-00 (330104 Proximity Probe) provides direct physical/electrical execution. The hardware operates by generating a high-frequency radio frequency (RF) field to detect static or dynamic distances between the probe tip and a conductive target material, outputting physical variations as an analog voltage shift back to a 3300 XL Proximitor Sensor.

The 3300 XL 8 mm probe operates on eddy-current scaling metrics tuned to AISI 4140 AISI steel targets unless calibrated otherwise. To maintain systematic loop verification, physical installation requires precise gap voltage validation. Field engineers must verify that the steady-state DC voltage reads a nominal target value (typically -10 VDC within the linear range) to center the probe within its calibrated 2.0 mm (80 mils) total linear range. Correct configuration eliminates cross-talk suppression failures when multiple probe tips are arrayed closely across rotor dynamics testing planes.
Q: What is the fluid resistance specification for the probe tip assembly?
A: The tip is constructed of polyphenylene sulfide (PPS) and is fluid-sealed against compatible lubricants, oils, and chemical vapors at the machine case interface.
Q: Can this 1.0-metre probe be coupled directly to a monitor without an extension cable?
A: No. The total electrical loop length between the 3300 XL Proximitor Sensor and the probe must match the system design (typically 5.0 metres or 9.0 metres). A 1.0-metre probe requires a specific 4.0-metre or 8.0-metre extension cable to maintain loop impedance matching.
