Q1: What is the primary function of the 330105-02-12-05-02-00?
It is a reverse-mount eddy-current proximity probe used for non-contact measurement of shaft vibration, axial position, and Keyphasor reference on rotating machinery. It outputs a voltage proportional to the gap between the probe tip and the conductive shaft surface .
Q2: What makes "reverse mount" different from standard probes?
A reverse-mount probe is installed from behind the mounting surface, with the cable exiting in the opposite direction. This design is ideal for compact machinery layouts or locations with limited frontal access where standard forward-mount probes cannot fit .
Q3: What are the key specifications for this probe?
Cable length: 0.5 meter
Scale factor: 7.87 V/mm (200 mV/mil)
Linear range: 2.0 mm (80 mils)
Operating temperature: -51°C to +177°C
Thread: 3/8-24 UNF
Q4: How do I ensure proper system compatibility?
The total electrical length of the probe cable plus extension cable must equal the Proximitor sensor's rated system length. Since this probe has a 0.5m cable, you must pair it with a 0.5m Proximitor (or use an extension cable to match a longer system) . All 3300 XL components are fully interchangeable without bench calibration.
Q5: What are the typical applications for this probe?
Common applications include steam turbines, gas turbines, centrifugal compressors, pumps, and motors where space constraints require reverse-mount installation. It is widely used in power generation, oil & gas, petrochemical, and heavy manufacturing industries for machinery protection and predictive maintenance.
The Bently Nevada 330105-02-12-05-02-00 is an 8 mm reverse-mount proximity probe from the 3300 XL series, engineered for non-contact vibration and position monitoring in space-constrained machinery.
The Bently Nevada 330130-085-00-00 is an 8.5-meter standard extension cable for the 3300 XL 8 mm Proximity Transducer System.

The Bently Nevada 21000-00-00-15-030-04-00 is a Proximity Probe Housing Assembly from the 21000 series, designed to provide a secure, environmentally sealed mounting interface for reverse-mount proximity probes on critical rotating machinery.
The Bently Nevada 330780-50-00 is a 5.0-meter Proximitor® Sensor for the 3300 XL 11 mm Proximity Transducer System. It receives signals from a 3300 XL 11 mm probe and its extension cable, conditioning them into a linear voltage output proportional to shaft displacement for radial vibration, axial thrust position, and Keyphasor measurement.
The Bently Nevada 21747-040-00 is a 4-meter Proximitor probe extension cable designed for the 3300 and 7200 Series Proximity Transducer Systems. It connects a proximity probe to its Proximitor sensor, transmitting high-frequency eddy-current displacement signals for vibration and shaft position monitoring on critical rotating machinery.
The Bently Nevada 330710-00-060-10-02-00 is a 3300 XL 11 mm Proximity Probe designed for non-contact vibration and position measurement on large, fluid-film bearing machinery. Its 11 mm tip provides a longer linear range compared to the standard 8 mm system, making it ideal for applications requiring greater measurement span, such as axial thrust position, differential expansion, and radial vibration on steam turbines, centrifugal compressors, and large pumps.
The Bently Nevada 330103-00-11-50-02-00 is a 3300 XL 8 mm proximity probe with a metric M10×1 thread and a 5.0-meter integral cable terminated with a miniature coaxial ClickLoc™ connector. This extended-reach configuration features a 110 mm overall case length and connects directly to a Proximitor® sensor without requiring an extension cable for short-run installations.
The Bently Nevada 990-10-XX-01-00 (MOD 165353-01) is a two-wire, loop-powered Vibration Transmitter designed for OEMs of centrifugal air compressors, small pumps, motors, and fans. It accepts input from a 3300 NSv proximity probe and its matching extension cable, conditioning the signal into a 4–20 mA output proportional to peak-to-peak vibration amplitude.
