The 330171-00-08-90-01-05 is an industrial-grade non-contacting eddy current proximity probe. It complies with the American Petroleum Institute API 670 international standard, and is primarily used for real-time high-precision monitoring and over-vibration protection of shaft vibration, axial displacement (position), and rotational speed (Keyphasor) on industrial rotating machinery such as steam turbines, compressors, and large water pumps.

3300 XL Proximitor Sensor(ref 141194-01)
When combined with a 3300 XL Proximitor Sensor, the system provides an output voltage that is directly proportional to the distance between the probe tip and the observed conductive surface. The system can measure both static (position) and dynamic (vibration) data. Its primary use is in vibration and position measurement applications on fluid-film bearing machines, as well as Keyphasor measurement and speed measurement applications. The system provides an accurate, stable signal output over a wide temperature range.
All 3300 XL Proximity Transducer Systems achieve this level of performance with complete interchangeability of components, eliminating the need for individual component matching or bench calibration. The probe features corrosion-resistant, gold-plated brass ClickLoc connectors. These connectors require only finger-tight torque (connectors will "click"), and the specially engineered locking mechanism prevents the connectors from loosening. The connectors require no special tools for installation or removal. Connector protectors can be supplied separately for installation in the field to provide increased environmental protection.

Power Generation Industry
Monitors rotor radial vibration and axial displacement of large steam turbine generators to prevent rotor-to-stator rubbing.
Oil & Gas Upstream
Used on high-pressure water injection pumps on offshore drilling platforms for bearing wear monitoring under continuous heavy loads.
Iron & Steel Metallurgy Industry
Monitors the hydrodynamic bearing journal condition of large blast furnace blowers and hot rolling high-pressure descaling pumps.
Pulp & Paper Industry
Monitors the dynamic radial impact on bearings caused by the high-speed refining rolls of large pulp refiners.
Water Conservancy & Hydro-power
Monitors the swing (radial displacement) of guide bearings and the shaft lift-up of vertical hydro-generator units.
Industrial Gases & Refrigeration
Monitors the shaft centerline plot of centrifugal refrigeration compressors within air separation units in confined spaces.
When using the 330171-00-08-90-01-05 proximity probe, strictly control the installation gap (initial voltage calibration) and avoid cross-threading or impacting the probe tip. Ensure the probe tip is free from surrounding metal interference by maintaining proper side clearance, and tighten it to the specified torque. Additionally, avoid sharp bends during cable routing, ground the shield at the monitor end only, and seal the connectors against oil and moisture to ensure micron-level vibration measurement accuracy and long-term stability.
This model features an M10×1 metric thread with an 80mm fully threaded case, an integrated 9.0-meter direct-connect cable, and a loosen-preventing ClickLoc connector. Holding multiple hazardous area approvals (ATEX/IECEx/CSA) and supporting a wide operating temperature range of -35°C to +177°C, it delivers high-precision real-time shaft vibration and axial position monitoring for rotating machinery such as steam turbines and compressors.
The 330171-00-08-90-01-05 is a Bently Nevada 3300 XL Series 8mm non-contacting eddy current proximity probe. It is primarily used for monitoring shaft vibration, axial position, and rotational speed in industrial rotating machinery.
How do you use the 330171-00-08-90-01-05?
Thread the probe into the machinery bearing housing or mounting bracket so that the probe tip faces the observed shaft surface. Since it comes with an integrated 9-meter cable, its end connector bypasses the extension cable and plugs directly into a compatible 3300 XL 9.0-meter Proximitor.
What connector is equipped on the 330171-00-08-90-01-05?
The suffix "-01" indicates that it is equipped with a standard coaxial ClickLoc miniature connector, which features a patented locking mechanism to withstand intense mechanical vibration in heavy industries.
What is the measuring range of the 330171-00-08-90-01-05?
It provides a 2.0 mm (80 mils) linear measuring range. Its standard nominal scale factor (ASF) is 7.87 V/mm (200 mV/mil).
What is the standard calibration material for the 330171-00-08-90-01-05?
Its standard factory calibration target material is AISI 4140 steel. If the observed shaft is made of another special metal alloy, calibration compensation must be performed on the Proximitor.
