The 330104-00-10-05-01-BR belongs to Bentley Nevada's renowned 3300 XL 8mm eddy current sensor system. It is a non-contact, high-precision measurement probe specifically designed for the dynamic and static measurement of shaft behavior in industrial rotating machinery. It precisely converts minute mechanical displacements into electrical signals by emitting a high-frequency electromagnetic field onto the measured metal surface.
One 3300 XL 8 mm probe
One 3300 XL extension cable
One 3300 XL Proximitor Sensor
The 3300 XL 8 mm system delivers the most advanced performance in our eddy current proximity transducer systems. The standard 3300 XL 8 mm 5-meter system also fully complies with the American Petroleum Institute’s (API) 670 Standard for mechanical configuration, linear range, accuracy, and temperature stability. All 3300 XL 8 mm proximity transducer systems provide this level of performance and support complete interchangeability of probes, extension cables, and Proximitor sensors, eliminating the need to match or bench calibrate individual components. Each 3300 XL 8 mm Transducer System component is backward compatible and interchangeable with other non XL 3300 series 5 mm and 8 mm transducer system components. This compatibility includes the 3300 5 mm probe, for applications in which an 8 mm probe is too large for the available mounting space.

Thermal Power
Measures radial vibration and axial displacement of large steam turbine generator shafts to prevent catastrophic friction between rotating and stationary components.
Petrochemical Refining
Monitors real-time shaft vibration of core cracking gas compressor trains, safely deployed in explosive gas hazardous areas via its -BR explosion-proof certification.
Iron & Steel Metallurgy
Monitors bearing vibration of heavy blast furnace blowers under high-dust environments, utilizing the probe's 177°C high-temperature rating to withstand melt shop heat.
Hydroelectric Power
Monitors the radial swing (runout) of large vertical hydro-turbine generator shafts and the axial displacement of thrust bearings.
Cement Manufacturing
Monitors vibration of clinker rotary kiln drive shafts and large exhaust fan shafts, leveraging high gas-tight sealing (7.0 bar) to block ambient dust from entering bearings.
Nuclear Power
Provides continuous redundant monitoring of speed and axial displacement for high-speed pumps, such as main feedwater and condensate pumps, in the conventional island.
When using this reverse-mount probe, the initial gap must be strictly locked at approximately -10 Vdc by monitoring the Proximitor voltage to prevent the probe tip from physically rubbing against the shaft surface. Because the built-in 0.5m cable is short and unarmored, avoid aggressive pulling during installation, maintain a minimum bend radius of 25.4mm, and always install the connector protector to seal out oil and moisture. Furthermore, the probe must be paired exclusively with 3300 XL series cables and Proximitors to ensure a precise total system length of 5 or 9 meters, with re-calibration required if the shaft material is not AISI 4140 steel. For hazardous area operations, ensure its -BR (INMETRO) explosion-proof label remains intact and the housing is properly grounded.
The 330104-00-10-05-01-BR is an industrial-grade, reverse-mount 3300 XL 8mm proximity probe featuring an M10×1 threaded case (1.0-inch overall length), a 0.5-meter unarmored cable with a miniature ClickLoc connector, and a Brazilian INMETRO explosion-proof certification. Operating as a core component of the eddy current sensor system, it provides an output voltage with a standard linear scale factor of 7.87 V/mm (200 mV/mil) over a 2.0 mm (80 mils) linear range. This output is directly proportional to the distance between the probe tip and the observed conductive surface (typically AISI 4140 steel) and can measure both static (position) and dynamic (vibration) values. The system’s primary applications are vibration and position measurements on fluid-film bearing machines, as well as Keyphasor reference and speed measurements within a wide temperature range of -51 °C to +177 °C.
The 330104-00-10-05-01-BR is a 3300 XL series 8mm eddy current proximity probe manufactured by Bently Nevada. It is specifically designed for high-precision, non-contact measurement of axial position, radial vibration, and rotational speed of shafts in large industrial rotating machinery.
How to use proximity probes like 330104-00-10-05-01-BR?
The probe needs to be thread-mounted on a machine bracket or bearing housing, positioning the probe tip at a safe gap distance from the rotating shaft's metallic surface. Its tail cable is then connected to a dedicated 3300 XL extension cable and a Proximitor Sensor to output a voltage signal readable by a monitoring system.
What is the core working principle of 330104-00-10-05-01-BR?
It operates on the eddy current physical principle. The coil at the probe tip emits a high-frequency electromagnetic field; as a conductive metal shaft approaches, eddy currents are generated on its surface, changing the probe's impedance, which the connected Proximitor then converts into a voltage output directly proportional to the gap distance.
Is 330104-00-10-05-01-BR interchangeable with older legacy 3300 8mm probes?
Physically compatible, but mixing is not recommended. The 3300 XL probe features major technical upgrades in physical durability. If it is mixed with an older, non-XL legacy proximitor, the system's overall electrical scaling characteristics will degrade.
If the industrial site needs replacement, what is the typical maintenance lifecycle of this probe?
Under proper installation without mechanical impacts, the probe typically boasts a maintenance-free lifecycle of 10+ years. Because it involves critical plant safety loops, replacements during outages must be verified with factory calibration certificates.
