The 168209-0317-127-90-05-01 s an 8mm non-contact eddy current proximity probe with a 3/8-24 thread, a 31.7mm unthreaded length, and a 9-meter integral cable, holding CSA, ATEX, and IECEx hazardous area certifications.
CSA, ATEX, and IECEx hazardous area certifications
Features a stainless steel case and a chemically resistant probe tip material
Output signals link directly with standard Bently Nevada proximity monitoring systems
This product holds multiple hazardous area certifications, including CSA, ATEX, and IECEx. Its operating and storage temperature ranges from -51°C to +177°C, and under specific intrinsically safe circuit conditions, its temperature classification spans from T1 to T5. In field operations, the probe must connect to a matching 3300 XL Proximitor Sensor, which supplies a high-frequency excitation signal to generate an electromagnetic field around the Polyphenylene Sulfide (PPS) plastic probe tip.
When the target metallic shaft surface experiences displacement or vibration, it generates eddy currents on the shaft surface, causing a linear change in the system's impedance. The Proximitor converts this variation into a continuous voltage signal with a nominal incremental scale factor of 7.87 V/mm (200 mV/mil), delivering data to continuous monitoring systems for tracking radial shaft vibration, axial position (thrust), and Keyphasor speed on rotating machinery like centrifugal compressors, steam turbines, pumps, and blowers.

When using the 168209-0317-127-90-05-01 probe, set the initial installation gap via the 3/8-24 thread and avoid impacts on the case. Do not cut or splice the 9-meter integral coaxial cable, and avoid tight bending radii during routing. Lock the ClickLoc connector protector to prevent oil or water ingress.
The 168209-0317-127-90-05-01 probe operates in temperatures up to 177°C, holds multiple hazardous area certifications, and monitors shaft vibration and axial displacement of rotating machinery in restricted spaces.

What product is 168209-0317-127-90-05-01?
This is a non-contact eddy current proximity probe for measuring shaft vibration and axial displacement in rotating machinery, belonging to the 3300 XL 8mm series with a 3/8-24 thread configuration.
What are the physical structure characteristics of 168209-0317-127-90-05-01?
It features a 3/8-24 UNF thread and a short case without a rigid protective armor sleeve.
How does 168209-0317-127-90-05-01 work?
The proximitor sensor sends a high-frequency signal to create a magnetic field around the probe tip; as the metallic shaft surface moves closer, eddy currents form on the target, changing the system impedance and outputting a voltage proportional to the gap.
