330102-00-12-05-02-05 | Bently Nevada | 3300 XL 8 mm Proximity Probes

Technical Overview

The Bently Nevada 330102-00-12-05-02-05 is a 3300 XL 8 mm reverse mount proximity probe, a component of an eddy current transducer system designed for non-contact displacement and vibration measurement on rotating machinery. The probe functions by emitting a high-frequency radio frequency (RF) signal from its encapsulated tip. When positioned near a conductive target material, such as a machine shaft, this RF field induces eddy currents on the surface of the target. The interaction between the probe’s field and the eddy currents creates an impedance change in the probe’s coil, which is directly proportional to the gap between the probe tip and the target surface. This raw signal is transmitted through its integral 0.5-meter cable to a 3300 XL extension cable and subsequently to a 3300 XL Proximitor Sensor. The Proximitor Sensor demodulates and linearizes the signal, producing a precise DC voltage output that corresponds to the physical gap. This conditioned signal is then supplied to a Bently Nevada 3500 Series monitoring system for continuous machine protection, diagnostics, and data logging.

Operational Capabilities

In Oil & Gas and Power Generation applications, the 330102-00-12-05-02-05 probe is integral to Machinery Protection Systems (MPS) on critical assets like gas and steam turbines, compressors, and large motor-pump sets. It provides the primary measurement for radial vibration, axial thrust position, and shaft eccentricity. The probe’s construction from AISI 304 stainless steel ensures high reliability in corrosive and high-temperature environments. Its tip is hermetically sealed with a high-pressure, injection-molded Ryton® PPS material, preventing ingress of oil and process fluids. The specified operating temperature range for the probe tip is -34 °C to +177 °C (-29 °F to +350 °F). The included agency approvals (CSA, ATEX, IECEx) certify the 330102-00-12-05-02-05 for safe operation as an intrinsically safe apparatus in specified hazardous areas, a mandatory requirement for many hydrocarbon processing and power plant environments. The system demonstrates high long-term stability, minimizing calibration drift and ensuring consistent machine protection over extended operational periods.
