Product Description
330103-00-16-50-12-00 Bently Nevada 3300 XL 8 mm Probe
The Bently Nevada 330103-00-16-50-12-00 is a heavy-duty, reverse-mount 3300 XL 8 mm proximity probe engineered to monitor dynamic shaft vibration and axial position inside critical, tight-clearance rotating machinery. It solves the costly engineering headache of adjusting sensors in inaccessible spaces by utilizing a rear-locking, threadless forward body that slips cleanly through machine housings, allowing all depth calibration to be handled from the exterior flange.
Note: While some buyers inadvertently search for this model under "RAM memory backup" due to mixed catalog listings, this is a hardware eddy-current proximity sensor used for mechanical shaft monitoring, not an electronic memory battery or RAM chip.
Compared to standard front-mounting models, this premium reverse-mount configuration features a highly durable FluidLoc® armored cable that blocks hot lubricating oils from wicking into external electronics, delivering an API 670 compliant 2.0 mm (80 mil) linear sensing range that handles the toughest industrial turbine environments with absolute signal precision.
Automation Engineer's Note
"When working with the 330103-00-16-50-12-00, keep in mind that its 5.0-meter integrated length means it is a 'total-length' system component. Unlike short 1.0-meter probes that require a separate extension cable to meet the Proximitor's impedance loop tuning, this 5.0-meter probe hooks directly into a 5.0-meter tuned Proximitor sensor. Do not add an extension cable to this circuit, or you will throw off the scale factor and ruin your vibration metrics. When setting the physical gap distance, use a digital multimeter at the Proximitor to dial in a raw DC voltage readout of exactly -10.0 Vdc--this anchors the sensor dead-center on its linear curve to allow room for both rapid radial vibrations and slow thermal axial growth."
Frequently Asked Questions
Q: Why do some industrial product descriptions mention 'Internal RAM Memory Backup' for this Bently Nevada part number?
A: This is a common e-commerce catalog data error. The 330103-00-16-50-12-00 is exclusively a physical eddy-current proximity probe used to track mechanical shaft displacement. It has no electronic memory, RAM, or battery backup functionality. If your system requires a RAM memory backup battery, you are likely looking for a power/battery module for a programmable logic controller (PLC) or a specific memory module inside a 3500 protection rack monitor, not this sensor.
Q: Why would a plant choose a 'Reverse Mount' probe style over a standard threaded probe?
A: On high-speed machinery like centrifugal compressors or multi-stage gearboxes, bearing caps are tightly integrated and hard to access. A standard probe forces technicians to spin the entire sensor assembly inside a dark casing, running a huge risk of cross-threading or smashing the probe tip against the shaft. The reverse-mount configuration slides smoothly through the access hole from the inside out, and is secured entirely by an exterior locking flange on the outside of the machine.
Q: What is the significance of the FluidLoc® feature denoted by the '12' option code?
A: In high-pressure turbine housings, oil mist can seep into the minute gaps between standard cable copper wire braids and the outer insulation layer. Over months of service, this oil travels like a straw, eventually leaking into and ruining your external junction terminal boxes. The FluidLoc® internal barrier acts as a physical plug inside the cable insulation, sealing the wire core completely and halting oil migration in its tracks.

The Amikon Benefit: 100% Original | Factory Sealed | Lowest Lead Times
Global Distribution Network
Amikon supplies industrial automation parts to more than 150 countries, covering a wide mix of regions.
The Americas: especially the USA and Canada, still rely quite a lot on replacement parts. Many sites there are older facilities like refineries or chemical plants.
Europe: similar, with countries such as Germany, UK, France and Italy. A lot of work there is about keeping existing systems running rather than new installations.
Asia-Pacific: includes China, Japan, South Korea, Singapore and Australia. Industries there range from semiconductors to shipbuilding and mining, depending on the country.
Middle East and Africa: like UAE, Saudi Arabia, Qatar and South Africa, are more focused on energy-related operations, mainly oil, gas and power sectors.
