The Bently Nevada 31000-16-10-15-030-03-02 is a specialized proximity probe housing designed to physically protect a proximity probe and its integral cable within harsh industrial environments. Its primary function is to provide a secure, environmentally sealed mounting point on rotating machinery for acquiring critical vibration and position data. The housing is constructed from 304 Stainless Steel, offering robust protection against physical impact and corrosion. This specific configuration, 31000-16-10-15-030-03-02, features a 3/4-14 NPT external mounting thread for direct installation into a machine case. Internally, it accommodates a Bently Nevada 3300 XL 8 mm or 3300 5 mm probe, which is positioned by a 1.0-inch stinger (probe sleeve). The housing facilitates the signal path from the probe tip to the Bently Nevada 3500 Monitoring System. The probe, connected via an extension cable to a Proximitor Sensor, generates a high-frequency RF signal. The resulting eddy current field is used to measure the distance to the observed conductive target. The Proximitor Sensor conditions this signal into a calibrated DC voltage proportional to the gap, which is then transmitted to a 3500/42M Proximitor/Seismic Monitor module for analysis, alarming, and machinery protection.

The Bently Nevada 330102-00-60-10-01-05 is an 8 mm reverse-mount eddy current proximity probe designed for non-contact measurement of vibration and displacement. It functions as a core component of the 3300 XL 8 mm Proximity Transducer System, which also includes an extension cable and a Proximitor Sensor. The probe operates by having the Proximitor Sensor generate a high-frequency radio frequency (RF) signal, which is transmitted through the extension cable and radiated from the probe's tip into a small electromagnetic field. When a conductive target, such as a machine shaft, enters this field, eddy currents are induced on its surface. These currents create a secondary magnetic field that opposes the primary field, causing a measurable change in the RF signal's amplitude. This change is directly proportional to the gap between the probe tip and the target surface. The Proximitor Sensor demodulates this signal, converting it into a DC voltage that accurately represents the physical distance. This conditioned voltage signal is then transmitted to a monitoring system, such as the Bently Nevada 3500, for real-time analysis of radial vibration, axial position, and shaft speed.

Q: What systems is the 330102-00-60-10-01-05 compatible with?
A: The 330102-00-60-10-01-05 probe is a component of the 3300 XL 8 mm Transducer System. For proper operation, it must be used with a 3300 XL extension cable and a 3300 XL Proximitor Sensor (e.g., part number 330180). This complete transducer system is fully compatible with Bently Nevada monitoring systems, including the 3500 Series Machinery Protection System and ADRE Sxp/408 DSPi data acquisition systems. It is not electrically or mechanically compatible with components from other transducer series, such as the 7200 or 3000 series.
Q: What are the installation requirements?
A: As a reverse-mount probe, the 330102-00-60-10-01-05 is installed from inside the machine housing, with the probe body extending outward. A clearance hole must be drilled through the machine case to accommodate the 8 mm probe tip. The target area on the observed shaft must be smooth, free of surface defects, and have a minimum diameter of 10.7 mm (0.42 in) to ensure measurement accuracy. The probe's gap should be set to the center of its linear range, typically corresponding to -10.0 Vdc. The ClickLoc connector must be tightened to the specified torque to ensure a secure, environmentally sealed connection. Cable routing must avoid areas of extreme heat, physical abrasion, and proximity to high-voltage power lines to maintain signal integrity.
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.
