Bently Nevada 330104-00-03-10-02-00 | 3300 XL 8mm Threaded Extended Tip Probe

Field installation constraints often demand sensors that combine fixed threaded mounting and extended sensing reach — a gap the Bently Nevada 330104-00-03-10-02-00 perfectly fills. Part of the trusted 3300 XL 8mm transducer lineup, this probe merges the secure screw-in stability of threaded probes with the deep-bore accessibility of extended tip designs. It stands apart from standard 330101 straight probes and basic 330103 extended tip models, built specifically for tight, recessed mounting points that require both rigid fixed installation and extended sensing depth. Fitted with a short 3-meter factory cable and 10mm elongated tip, it is a go-to solution for compact machinery setups in power generation and petrochemical plants, delivering consistent, repeatable vibration and displacement readings for critical rotating equipment.

Practical Part Number Code Breakdown

Every suffix in this full part number corresponds to real-world installation and hardware traits, letting maintenance and engineering teams verify exact fit before onsite installation:

Complete On-Site Monitoring System Matching

Proximity probes do not function standalone. For reliable, accurate data acquisition and machinery protection interlocks, pair this unit with matched system components:

• 330180 proximitor sensor: Converts real-time probe gap changes into stable linear voltage signals for system reading

• 330130 extension cable: Used only when site layout requires longer wiring than the factory 3-meter cable provides

• Threaded extended tip mounting hardware: Specialized lock nuts and gaskets to secure the probe in deep bores and prevent vibration loosening

• 3500/42 or 3500/45 monitor modules: Rack-mounted units that process vibration and thrust data, trigger alarms and execute safety interlocks

Site-Specific Product Strengths

This 330104 model solves two common onsite installation headaches at once. Its threaded body eliminates probe shifting and position drift, a frequent issue with bracket-mounted straight probes during long-term unit operation. The 10mm extended tip overcomes the problem of thick turbine and compressor casings that block standard-length sensors from reaching rotor measurement surfaces.

The compact 3-meter cable is a key advantage for densely arranged equipment layouts, eliminating excess slack cable that can snag, vibrate or accumulate industrial grime onsite. Factory-molded one-piece cable construction removes splice points, one of the most common causes of intermittent signal faults in legacy TSI monitoring systems. The non-contact measurement design means zero wear over years of continuous operation, cutting down routine sensor replacement and onsite maintenance workload.

Common Industrial Deployment Scenarios

Maintenance and upgrade teams primarily deploy this probe for tight-space machinery monitoring and system retrofits. In thermal power plants, it serves steam turbine bearing vibration and thrust position checks, specifically on equipment with deep factory-cast mounting holes. Petrochemical facilities use it on compact centrifugal compressors and turbo expanders where mounting space is limited and fixed screw-in installation is mandatory.

It is also widely used for overhaul and replacement projects on aging 3300 XL systems. As a drop-in compatible upgrade, it requires no casing machining or layout modifications, making it a cost-effective fix for outdated or failed legacy probes on critical production equipment.
