Petrochemical Case: 330103-00-05-50-12-00 BENTLY NEVADA
Machine: Siemens High-Speed Centrifugal Compressor (Petrochemical Plant).
Location: The BENTLY NEVADA Proximity Probe is installed directly on fluid-film journal bearings for critical X/Y radial vibration monitoring.
Location: The BENTLY NEVADA Proximity Probe is installed directly on fluid-film journal bearings for critical X/Y radial vibration monitoring.
Why this specific model was chosen:
M10x1 Metric Thread: The 3300 XL 8 mm Proximity Probe perfectly matches the European metric tapped holes in the bearing housing without requiring unapproved adapters.
50 mm Short Case: This compact BENTLY NEVADA 330103-00-05-50-12-00 sensor fits the tight internal clearances and avoids impacting the machine's outer enclosure shield.
5.0-Meter Integral Cable: This specific BENTLY NEVADA Proximity Probe configuration runs directly from the machine interior to the external junction box, eliminating intermediate extension cables and loose connector failures.
FluidLoc® Technology: The specialized cable on the BENTLY NEVADA Proximity Probe stops high-pressure lube oil from wicking through the cable interior into the sensitive electronics box.
Outcome
Deploying the BENTLY NEVADA 330103-00-05-50-12-00 completely solved field oil leakage and false trips. During a severe machine surge, the 330103-00-05-50-12-00 BENTLY NEVADA loop successfully captured a sudden 50 µm vibration spike, triggering an automatic safe shutdown and protecting the multi-million dollar compressor shaft.

3300 XL 8 mm Proximity Probe FAQ
Q1: What is the exact mechanical configuration of the BENTLY NEVADA 330103-00-05-50-12-00 proximity probe?
A1: The BENTLY NEVADA 330103-00-05-50-12-00 is a 3300 XL 8 mm eddy-current proximity sensor configured with an M10 x 1 metric thread, a 0 mm unthreaded length (fully threaded body), and a 50 mm overall case length. It features a 5.0-meter integral cable terminated with a miniature gold-plated male ClickLoc™ coaxial connector. It requires no agency approvals (standard industrial configuration).
Q2: Why does the BENTLY NEVADA 330103-00-05-50-12-00 feature a 5-meter total length instead of a standard 1-meter probe?
A2: The 5.0-meter continuous system design of the 3300 XL 8 mm Proximity Probe is engineered to eliminate intermediate extension cables. In high-vibration machinery, intermediate connectors are prone to moisture ingress or mechanical loosening. By routing the 3300 XL 8 mm Proximity Probe directly from the bearing housing to the external local enclosure, you eliminate the mid-point connection entirely, drastically lowering the risk of false machine trips.
Q3: What specific advantage does the FluidLoc® cable option provide for the BENTLY NEVADA 330103-00-05-50-12-00 probe?
A3: The "12" suffix in the part number specifies that the BENTLY NEVADA 330103-00-05-50-12-00 is equipped with a patented FluidLoc® triaxial cable. High-speed compressors maintain high internal lube oil pressures. Ordinary sensor cables can act as a wick, drawing oil out through the cable interior via capillary action. The 330103-00-05-50-12-00 BENTLY NEVADA utilizes internal sealing barriers to completely block oil migration, keeping external junction boxes dry and preventing signal decay.
Q4: How should the BENTLY NEVADA 330103-00-05-50-12-00 probe be calibrated and paired within a complete loop?
A4: The 330103-00-05-50-12-00 BENTLY NEVADA has a factory-calibrated Scale Factor of 7.87 V/mm (200 mV/mil) when observing standard AISI 4140 steel. Crucially, because it already contains a 5.0-meter integral cable, the 3300 XL 8 mm Proximity Probe must connect directly to a matching 5-meter Proximitor® Sensor (e.g., PN 330180-50-XX) without an extension cable to avoid altering the loop capacitance and throwing off calibration.
Q5: What are the installation torque specifications and thread limitations for the 330103-00-05-50-12-00 BENTLY NEVADA?
A5: For a standard forward-mounted M10 x 1 thread, the 330103-00-05-50-12-00 BENTLY NEVADA has a recommended installation torque of 7.5 N·m (66 in·lbf) and a maximum limit of 22.6 N·m (200 in·lbf). To prevent structural binding inside the machine frame during tight installations, the maximum internal thread engagement length for the BENTLY NEVADA Proximity Probe casing must not exceed 15 mm.
