Features:

  • Large 11 mm Tip Diameter for Extended Linear Range Measurement
  • M14 x 1.5 Thread with Armored Cable Protection
  • Operates in Conjunction with 3300 XL Extension Cable and Proximitor Sensor
The 330704-000-100-10-02-00 operates as the 3300 XL 11 mm Proximity Probe in a 3300 XL transducer system, providing reliable non-contacting vibration and displacement measurements on fluid film bearing machines. It continuously delivers a 3.94 V/mm (100 mV/mil) output signal through the miniature coaxial ClickLoc connector and distributes this signal through the extension cable to support steady state operation of the Proximitor sensor and monitoring system. Seamless signal transmission is standard with the 330704-000-100-10-02-00, however using an optional FluidLoc cable option will prevent oil and other liquids from leaking out of the machine through the cable's interior. The 330704-000-100-10-02-00 has made improvements in several areas over previous 7200-series 11 mm and 14 mm transducer designs in addition to incorporating universal M14 x 1.5 thread capability with 0 mm unthreaded length.

The 330704-000-100-10-02-00 provides essential measurement functions for axial position monitoring, and is a critical component of the thrust bearing measurement path, directly affecting the proper, normal operation of the overall machinery protection system. One 330704-000-100-10-02-00 probe is required per measurement point with overall case length of 100 mm. The 330704-000-100-10-02-00 occupies only a single probe mounting position and is always located at the measurement point (thrust bearing face, the dedicated axial position monitoring position).

For Differential Expansion applications, the 3300 XL System requires the 330704-000-100-10-02-00 probe with its 11 mm tip to accommodate the longer linear range necessary for ramp differential expansion measurements on steam turbines. In addition to standard axial position operation, the extended range configuration also performs rod position measurement. The 3300 XL probe configuration executes measurement using the patented TipLoc molding method specified in the probe design. Using this method, the 330704-000-100-10-02-00 system continually maintains a robust bond between the probe tip and probe body. If the system detects that the 330704-000-100-10-02-00 probe cable is subjected to pulling force, the CableLoc design providing 330 N (75 lb) pull strength will automatically secure the cable attachment and prevent signal interruption.

The 330704-000-100-10-02-00 Bently Nevada 3300 XL 11 mm Proximity Probe may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
The 3300 XL 11 mm Proximity Probe, specifically model 330704-000-100-10-02-00, is a precision-engineered sensing device designed for demanding industrial vibration and displacement monitoring applications. This particular configuration features an M14 x 1.5 threaded case with armored cable protection, offering enhanced durability in harsh operating environments. The probe incorporates a 0 mm unthreaded length and an overall case length of 100 mm, with a total cable length of 1.0 meter (3.3 feet) terminated with a miniature coaxial ClickLoc connector. The standard cable construction ensures reliable signal transmission while the gold-plated brass ClickLoc connector design provides secure, vibration-resistant connections that prevent loosening during operation.

The 330704-000-100-10-02-00 probe is an integral component of the Bently Nevada™ 3300 XL 11 mm Proximity Transducer System, which delivers a precise 3.94 V/mm (100 mV/mil) output for non-contacting vibration and displacement measurements on fluid film bearing machines. The large 11 mm probe tip diameter enables this transducer system to achieve a significantly longer linear measurement range compared to the standard 3300 XL 8 mm system. This extended range capability makes the 330704-000-100-10-02-00 particularly suitable for critical axial (thrust) position measurements where large shaft movements must be accurately tracked to prevent catastrophic bearing failures.

In steam turbine applications, the 330704-000-100-10-02-00 excels at performing ramp differential expansion measurements, monitoring the relative thermal growth between turbine casing and rotor during startup and shutdown sequences. The probe's robust construction, featuring patented TipLoc molding that creates a robust bond between the probe tip and body, ensures measurement integrity under extreme thermal cycling conditions. Additionally, the 330704-000-100-10-02-00 with its CableLoc design providing 330 N (75 lb) pull strength, is specifically engineered for reciprocating compressor rod position and rod drop measurements, where mechanical reliability is paramount to preventing compressor damage and ensuring operational safety.

The 330704-000-100-10-02-00 also serves critical functions in tachometer and zero speed detection applications, as well as providing phase reference (Keyphasor) signals for machinery diagnostics and balancing procedures. The armored cable option on this model makes it ideal for installations where mechanical protection against abrasion, cutting, or crushing is necessary. The probe comes standard with a locknut featuring pre-drilled safety wire holes, facilitating secure mechanical installation and compliance with safety standards in petrochemical, power generation, and oil and gas industries where this model is commonly deployed.
