Non-contact target sensing
The tip produces an eddy-current field rather than touching the rotating or stationary target.
Bently Nevada 330704-000-078-10-01-05 3300 XL 11 mm Probe
Product Description
Built around the larger-range 3300 XL 11 mm platform, Bently Nevada 330704-000-078-10-01-05 is an armored M14 x 1.5 proximity probe that senses shaft position without physical contact. The probe forms the machine end of a matched probe, extension-cable and Proximitor Sensor chain, where target distance changes the electrical response delivered to the monitor.
The ordered body of 330704-000-078-10-01-05 has no unthreaded section, a 78 mm overall case and a 1.0 m cable. Its standard cable terminates in a miniature ClickLoc connector with a protector, while the 11 mm system provides a 4.0 mm linear range and a 2.5 mm recommended gap for measurements requiring more range than the smaller NSv geometry.

Product Functions - 11 mm Displacement Sensing
Bently Nevada 330704-000-078-10-01-05 converts the changing gap at its 11 mm probe tip into the first electrical response of the displacement channel.
Four-millimetre measurement span
The matched system operates across an approximately 0.5 to 4.5 mm linear gap range.
Voltage-to-distance scaling
The Proximitor output changes at a nominal 3.94 V/mm scale factor over the published linear range.
System Integration - Matched 11 mm Signal Chain
The 1.0 m lead on 330704-000-078-10-01-05 is one defined section of the 11 mm transducer system rather than a stand-alone monitor cable.
Probe and extension cable
The ClickLoc joint couples the probe cable to the extension cable while retaining the coaxial signal path.
Extension cable and Proximitor
The extension cable terminates at the matching 11 mm Proximitor Sensor for signal conversion.
Proximitor and monitor
Three-conductor shielded field wiring carries the Proximitor output and common toward the monitoring channel.
Questions
Why does Bently Nevada 330704-000-078-10-01-05 need a 30.5 mm target?
The 11 mm system is specified around a recommended minimum flat-target diameter of 30.5 mm. A smaller target can change the scale factor and cross-talk behavior.
Is the 078 field on Bently Nevada 330704-000-078-10-01-05 a cable length?
No. It specifies a 78 mm overall probe case; the separate 10 field specifies the 1.0 m total probe length.
What initial gap is used with Bently Nevada 330704-000-078-10-01-05?
The recommended nominal gap for the matched 11 mm system is 2.5 mm. That setting places the target near the center of the 4.0 mm linear range.
Does Bently Nevada 330704-000-078-10-01-05 include cable armor?
Yes. The 330704 base identifies the M14 x 1.5 probe with armor.
Can Bently Nevada 330704-000-078-10-01-05 be mixed with an 8 mm Proximitor Sensor?
The probe belongs to the 3300 XL 11 mm transducer system. Its probe, extension cable and Proximitor Sensor must remain the matched 11 mm chain.
