Use attached product manuals when available. If the manual is not public yet, request the full file directly through RFQ.
Commercial Path
Product pages on DRIVEKNMS are designed to verify model, brand and series first, then move the buyer into one clean quotation path.
Technical Dossier
The Bently Nevada 128987 Series represents one of the most widely deployed proximity probe families in continuous heavy industrial operations worldwide. Installed across petrochemical refineries, LNG terminals, nuclear power stations, steel mills, and rotating machinery platforms, these probes form the sensing front-end of Bently Nevada's 3300 and 3500 Series vibration monitoring systems. Their eddy-current operating principle enables non-contact, real-time measurement of shaft radial vibration, axial position, and differential expansion — critical parameters for machinery protection and predictive maintenance programs.
Bently Nevada's proximity probe technology has evolved through several generations since the 1960s, with the 128987 Series representing a mature, standardized platform optimized for the 3300 XL and 3500 monitoring system ecosystems. Early Bently Nevada probes used proprietary connector standards and non-standardized cable impedances, creating significant compatibility challenges during system upgrades. The 128987 Series resolved these issues by adopting a consistent 5mm tip diameter standard, a defined sensitivity of 200 mV/mil (7.87 V/mm), and a linear measurement range of 0–80 mil (0–2.03 mm) across all variants.
The following SKUs represent the most commonly sourced models within the 128987 proximity probe family. Each is a discrete, calibrated component — not interchangeable without system reconfiguration.
All models operate at a nominal gap voltage of -10.5 VDC (at mid-range), with a system sensitivity of 200 mV/mil when paired with a compatible 3300 or 3500 Series proximitor. Target material must be AISI 4140 steel or equivalent for calibrated output.
Q: How are RFQ terms confirmed?
A: Quantity, required condition, documentation needs, destination and sourcing route are confirmed during RFQ review before quotation.
DriveKNMS operates a global procurement network specifically structured to address this gap. Our sourcing methodology includes:
Proximity probes are precision measurement devices — not commodity components. A probe with degraded tip geometry, damaged cable shielding, or connector corrosion will produce erroneous vibration readings, potentially masking developing machinery faults or triggering false shutdowns. DriveKNMS applies the following QC protocol to all 128987 Series units prior to dispatch:
