Bently Nevada 3000-00-10-30-36-02 Eddy Current Proximity Probe Product Specification
3000-00-10-30-36-02 is factory pre-calibrated eddy-current proximity probe from Bently Nevada’s standard 3000 series, manufactured in accordance with API670 industry standard for rotating machinery TSI supervision and safety protection systems. Paired with factory certified matching extension cable and compatible proximitor transducer, the product forms a complete closed-loop non-contact displacement measuring circuit. It converts tiny clearance variation between flush sensing end and metallic rotating shaft into proportional linear DC voltage signals, enabling continuous online measurement of radial shaft vibration, axial thrust displacement and Keyphasor rotational speed for critical rotating assets including steam turbines, centrifugal compressors, turbo-generator sets, boiler feedwater pumps and industrial blowers used in thermal power, petrochemical refining and metallurgical industries. Every finished probe passes factory capacitance matching test, full continuity inspection, alternating high-low temperature cycling aging test and connector sealing durability check before delivery to ensure stable linear output and consistent measuring accuracy under harsh industrial environments with fluctuating ambient temperature, dense lubricating oil mist and complicated electromagnetic interference. All measured signals are transmitted to Bently 3500 monitoring rack, site DCS or PLC control system to activate pre-alarm and emergency trip interlock protection, avoiding catastrophic mechanical breakdown of production equipment caused by excessive rotor offset or abnormal vibration amplitude.

1. Product Overview
3000-00-10-30-36-02 is factory pre-calibrated eddy-current proximity probe from Bently Nevada’s standard 3000 series, manufactured in accordance with API670 industry standard for rotating machinery TSI supervision and safety protection systems.

2. Part Number Coding Definition
The six-segment part number follows Bently standardized modular coding rules with fixed parameter definition per segment:3000 stands for core series designation of proximity probe with 11mm outer body diameter and standard M14×2 mounting thread, factory fixed nominal sensitivity of 3.94V/mm and fully compatible with Bently 3300 and 3500 series proximitor modules.00 means zero exposed unthreaded sensing tip; the probe detecting surface is flush with the thread end face without any protruding bare sensing rod, designed for flush mounting on compact bearing housings where extended probe tip into oil chamber is forbidden.10 defines total stainless steel probe housing length of 100 millimeters, optimized for ultra-shallow standard mounting holes on narrow-space bearing pedestals.30 is reserved internal production classification code following original factory specification.36 specifies factory pre-molded integrated probe cable length of 3.6 meters; this fixed length is fully calculated into total loop capacitance matching together with matched extension cable and supporting proximitor, arbitrary field cutting or replacement with unmatched cable will break preset impedance balance and trigger measurement zero drift and non-linear error.02 indicates standard cable and terminal configuration: non-armored fluoropolymer outer cable jacket fitted with gold-plated standard ClickLoc stainless steel threaded coaxial connector at cable terminal end, without additional metal armor sheath or custom modified plug structure. All mechanical and electrical parameters are locked after factory production and cannot be modified arbitrarily on installation site.
3. Mechanical and Raw Material Specifications
The internal sensing coil core is fabricated from high-stability precision alloy material and wrapped with high-temperature resistant modified PPS insulating layer, featuring steady dielectric constant, outstanding lubricant oil resistance and anti-corrosion property to maintain fixed capacitance value amid variable ambient temperature and long-term workshop oil mist immersion. Probe outer housing adopts precision CNC machined solid stainless steel with excellent anti-collision, rust-proof and high-temperature steam resistant performance for long-term installation near hot-running equipment casing. Internal signal transmission conductors use multi-strand oxygen-free copper wire to minimize high-frequency signal attenuation and improve anti-RFI electromagnetic interference capacity during signal delivery. Intermediate insulation layer is made of fluoropolymer with consistent dielectric property matching eddy-current induction working requirements. Outer protective jacket of integrated cable is wear-resistant thermoplastic elastomer to resist on-site mechanical scratch, dust accumulation and lubricant soaking erosion. The tail-end stainless steel ClickLoc connector is equipped with built-in elastic rubber sealing ring to block moisture, fine metal scraps and hydraulic oil from penetrating into inner wiring after locking with matched extension cable connector. The integral cable keeps proper flexible bending property for neat field wiring within specified minimum bending radius without insulation cracking.
4. Electrical Performance and Environmental Working Parameters
This proximity probe must cooperate with designated matching proximitor powered by negative DC supply ranging from -17.5VDC to -26VDC. The full measuring loop composed of probe, certified extension cable and supporting proximitor retains factory pre-calibrated fixed sensitivity of 3.94V/mm, with effective frequency response ranging from 0Hz up to 10kHz to satisfy both slow static axial thrust displacement tracking and high-frequency dynamic radial vibration sampling of high-speed rotating rotors.
Permitted continuous operating ambient temperature ranges from -40℃ to +120℃ to adapt low-temperature outdoor installation and high-temperature layout nearby hot turbine and compressor bearing housings; dry storage temperature is controlled between -55℃ ~ +95℃ under fully non-condensing storage environment. Applicable working relative humidity is limited within 5%RH ~ 95%RH with no internal condensation allowed inside probe and cable to prevent insulation degradation and inner core short-circuit fault. When installed above 1000 meters altitude, shorten regular inspection cycle appropriately to compensate heat dissipation reduction caused by thin atmospheric air density. The probe can withstand conventional industrial ambient vibration of 10Hz~60Hz; long-term continuous service in surroundings filled with strong corrosive chemical gas and uninterrupted hot steam immersion is strictly prohibited to extend service life of all internal core components.
5. Application Scope and Routine Maintenance Guidance
3000-00-10-30-36-02 short-body flush-type proximity probes are widely mounted on compact bearing pedestals of large-scale critical rotating equipment as core sensing parts of TSI machinery protection systems in thermal power plants, petrochemical refineries and heavy metallurgy production bases, collecting real-time shaft gap and vibration operational data to realize abnormal working condition pre-alarm and unit emergency shutdown interlock protection, efficiently preventing severe mechanical faults induced by excessive rotor displacement or abnormal vibration magnitude.
During periodic on-site maintenance work, field operators need regular visual inspection of probe housing integrity, outer cable jacket abrasion status and connector locking tightness to avoid intermittent signal loss triggered by loose connection or jacket rupture leading to oil infiltration into inner wiring. For fault spare replacement, only alternative spare probe with identical complete full part number specification is allowed for direct swapping; any change of flush tip structure, housing dimension or built-in cable length will alter total loop capacitance and result in distorted monitoring data and invalid measured values. All replacement spare probes complete full electrical parameter recalibration and alternating high-low temperature cycling aging test complying with original factory standards before outgoing delivery to guarantee full interchangeability during equipment overhaul and component replacement.
