Bently Nevada 330701-00-25-90-02-00 11 mm Proximity Probe
An unarmored 1/2-20 UNF probe with a 2.5-inch case and nine-metre standard cable.
Key Information
330701-00-25-90-02-00 is a 3300 XL 11 mm proximity probe with 1/2-20 UNF threads and no armor. Its code specifies zero unthreaded length, a 2.5-inch overall case and a complete 9.0 m cable.
The probe belongs to the longer-range 11 mm transducer system used for non-contacting vibration and displacement measurements. It must be paired with the matching 9 m Proximitor Sensor calibration.
Functions
- Senses shaft or target position without mechanical contact.
- Supports long-range position and vibration measurements where the 11 mm system is specified.
- Provides the probe element for a complete 3300 XL 11 mm monitoring loop.

Installation
- Compare the mounting thread, insertion depth and available cable route with the machine drawing.
- Connect directly to the correct system-length sensor; do not add an extension cable to a complete-length probe.
- Protect the unarmored cable from abrasion, hot edges and unsupported weight.
- Set the probe gap for the documented target material and verify channel polarity and scaling.
Lifecycle
- Keep the probe and Proximitor Sensor labels in one calibrated-loop record.
- Do not mix 3300 XL 11 mm parts with the earlier 7200-series system.
- Record the accepted gap voltage and waveform so future maintenance can detect installation changes.
FAQ
Does 330701-00-25-90-02-00 require an extension cable?
No. Its probe cable already forms the complete nine-metre length, so it is intended for the matching 9 m sensor without an added extension cable.
Can 330701-00-25-90-02-00 be used with a five-metre Proximitor Sensor?
No. The system-length calibration must match; use the designated nine-metre sensor arrangement.
What mechanical check matters before ordering 330701-00-25-90-02-00?
Confirm the 1/2-20 UNF thread, 2.5-inch case, insertion depth, locknut position and cable exit clearance.
Is 330701-00-25-90-02-00 interchangeable with an armored 330702 probe?
Not automatically. The cable construction differs, so routing, mechanical protection and the complete order code must be reviewed.
What evidence reduces replacement risk for 330701-00-25-90-02-00?
Provide the old probe and sensor labels, target material, mounting drawing, cable route, monitor configuration and required approval context.
