3300 XL 11 mm Proximity Probe Key Function
Non-Contact Measurement: Measures vibration and displacement on fluid film bearing machines without touching the surface.
Longer Linear Range: Features an 11 mm tip that provides a wide linear range of 4.0 mm (160 mils) with an output scale factor of 3.94 V/mm (100 mV/mil).
Five Core Applications:
Axial (thrust) position measurements.
Ramp differential expansion measurements on steam turbines.
Rod position or rod drop measurements on reciprocating compressors.
Tachometer and zero speed measurements.
Phase reference (Keyphasor) signals.
Mechanical Robustness: Built with a CableLoc design providing 330 N (75 lb) pull strength and gold-plated brass ClickLoc connectors to prevent accidental loosening.

3300 XL 11 mm Proximity Probe Testing Process
1. Resistance Test (Ohm Check)
Core-to-Jacket: Ensure the BENTLY NEVADA Proximity Probe reads 7.2 ± 0.8 Ω across its 5-meter cable.
Jacket-to-Case: Confirm the BENTLY NEVADA Proximity Probe reads ∞ Ω, verifying full isolation from machine ground.
2. Static Calibration (Bench Test)
Setup: Connect the BENTLY NEVADA Proximity Probe probe to its loop with -24 Vdc power over an AISI 4140 steel target micrometer.
Linear Check: Move the micrometer from 0.5 mm to 4.5 mm in 0.5 mm steps to verify the linear range.
Scale Target: Confirm the 330709-000-040-50-02-00 Proximity Probe output shifts by 1.97 Vdc per 0.5 mm change (3.94 V/mm).
3. Gap Installation (Field Test)
Voltage Target: Screw the probe into the machine casing until the DMM reads -10.0 Vdc (exact center gap of 2.5 mm).
Lock Torque: Tighten the locknut to 21.1 N·m and re-verify that the voltage remains stable at -10.0 Vdc.
3300 XL 11 mm Proximity Probe FAQ
Q1: What are the exact specifications of the 330709-000-040-50-02-00 BENTLY NEVADA?
A1: The 330709-000-040-50-02-00 Proximity Probe is a 3300 XL 11 mm probe with an M16x1.5 thread, 0 mm unthreaded length, 40 mm case length, 5.0-meter standard cable, ClickLoc connector, and standard agency approvals.
Q2: What is the target gap voltage for installing the 330709-000-040-50-02-00 BENTLY NEVADA?
A2: Screw the 330709-000-040-50-02-00 Proximity Probe in until the output reads -10.0 Vdc. This electrical value represents the optimal physical installation center gap of 2.5 mm (100 mils).
Q3: What target material and size does the 330709-000-040-50-02-00 BENTLY NEVADA require?
A3: The 3300 XL 11 mm Proximity Probe is factory-calibrated to AISI 4140 steel. It requires a minimum flat target diameter of 30.5 mm (1.2 in) to avoid edge effects and maintain scale accuracy.
Q4: What is the recommended mounting torque for the 330709-000-040-50-02-00 BENTLY NEVADA?
A4: Tighten the locknut of the 330709-000-040-50-02-00 Proximity Probe to a recommended torque of 21.1 N·m (187 in·lb). Do not exceed the maximum rated limit of 63.3 N·m (560 in·lb).
Q5: Does the 330709-000-040-50-02-00 BENTLY NEVADA require an extension cable?
A5: No. Because the 3300 XL 11 mm Proximity Probe features an integral 5.0-meter cable, it must plug directly into a 5-meter Proximitor Sensor without any extension cable to maintain proper loop calibration.
