The 330703-00-50-10-12-05 is a 3300 XL series 11 mm non-contact eddy current proximity sensor manufactured by Bently in the USA. It is a core front-end sensor for condition monitoring of large heavy industrial rotating machinery, primarily utilizing the eddy current principle.
Axial (thrust) position measurements
Phase reference (Keyphasor) signals
Tachometer and zero speed measurements
The 3300 XL 11 mm Proximity Transducer System has a 3.94 V/mm (100 mV/mil) output for non-contacting vibration and displacement measurements on fluid film bearing machines. The large 11 mm tip enables this transducer system to have a longer linear range compared to our standard 3300 XL 8 mm Transducer System. The 3300 XL 11 mm Proximitor Sensor is designed to replace the 7200-series 11 mm and 14 mm Transducer Systems. When upgrading from the 7200-series system to the 3300 XL 11 mm system, every component must be replaced with 3300 XL 11 mm components. In addition, the monitoring system must be updated. If using a 3500 Monitoring System, an updated version of the configuration software that lists the 3300 XL 11 mm Transducer System as a compatible option is required.

Nuclear Power
Monitoring the rotor relative expansion (differential expansion) of large 600MW/1000MW steam turbine high-pressure rotors to prevent blade rubbing during startup or shutdown due to uneven thermal expansion.
Thermal Power
Monitoring the axial displacement of ultra-large steam turbine generator units in nuclear conventional islands, where its large-sized tip maintains a stable linear measurement during major shaft movements.
Iron, Steel & Heavy Metallurgy
Monitoring the axial movement trends of blast furnace high-pressure axial blowers, its PPS tip fully tolerates the high heat and heavy dust conditions typical of steel mills.
Pulp & Paper
Monitoring the plate gap between the rotating and stationary discs in large pulping mill refiners, ensuring the micron-level clearance control required for precision refining.
Wind Power
Monitoring the relative axial displacement between the low-speed main gear shaft and high-speed shaft in MW-class wind turbine gearboxes, withstanding long-term severe outdoor freeze-thaw cycles.
When using the Bently Nevada 330703-00-50-10-12-05 probe, you must accurately adjust the initial static gap voltage to the linear center (typically -11 Vdc to -12 Vdc) with the machine at rest, lock it with a torque of 21.1 N·m to avoid any rotor rub, and never cut the integrated 1.0m cable, as it must match specific extension cables and Proximitors for a strict 5m or 9m system length. Additionally, the ClickLoc coaxial connector must be sealed with a dedicated protector against moisture/oil, and the cable must be routed with a minimum bend radius of 25.4 mm, secured inside protective conduits away from sharp edges, while strictly complying with the hazardous area explosion-proof regulations mandated by its -05 certification.
It is a 3300 XL series 11 mm non-contact eddy current proximity probe manufactured by Bently Nevada.
What is the standard output scale factor of 330703-00-50-10-12-05?
The standard linear voltage output scale factor for this 11 mm system is 3.94 V/mm (100 mV/mil).
How to properly install and adjust 330703-00-50-10-12-05?
Thread it into the bracket via M14 threads and monitor the Proximitor to adjust the static gap voltage to the linear center (typically around -11 or -12 Vdc due to the extended range) before locking it.
What is the core advantage of 330703-00-50-10-12-05 compared to standard 8mm probes?
It features a wider linear range, offering a total measuring gap of approximately 4.1 mm (160 mils)
If 330703-00-50-10-12-05 encounters severe mechanical shock, what is its maximum tolerance?
It possesses excellent seismic and shock-resistant design, withstanding a maximum peak load shock of 100 g.
