Description

Configured for non-contacting displacement and vibration measurements in 3300 XL 11 mm Proximity Transducer System networks, the Bently Nevada 330703-000-070-10-02-00 (330703 Proximity Sensor) provides direct physical/electrical execution.

Hardware Specifications

Machinery Monitoring & TSI Characteristics

This proximity sensor actively manages eddy-current probe scaling because it preserves strict geometric and electromagnetic characteristics at the 11 mm probe tip. Consequently, the wider tip design extends the linear range over standard 8 mm probes, which allows the loop to monitor larger physical displacements. The physical configuration ensures precise gap voltage validation across nominal -10 VDC targets during static calibration. Because the sensor head stabilizes the high-frequency RF field within the measurement gap, the component transmits clear rotor dynamics data, including radial vibration and axial thrust position, from large-scale industrial machinery without introducing measurement drift.

Frequently Asked Questions

Q: Does this proximity sensor support hot-swapping while the monitoring loop is live?

A: Yes. Technicians can safely disconnect the sensor from its extension cable or Proximitor while the rack is powered, provided they verify the surrounding atmosphere as non-hazardous.

Q: What physical design features do the options “000-070-10-02” specify for this probe assembly?

A: The “000” option specifies an unthreaded length of 0.0 inches, the “070” option designates a 7.0-inch total case length, and the “10” option provides a 1.0-meter total cable length. Furthermore, the “02” option specifies a miniature coaxial ClickLoc connector without an integrated connector protector.

Q: Can this 11 mm probe interface with standard 3300 XL 8 mm Proximitor sensors?

A: No. The 3300 XL 11 mm probe requires a dedicated 3300 XL 11 mm Proximitor sensor and matching 11 mm extension cable because the scale factor is 3.94 V/mm (100 mV/mil), which differs fundamentally from the 8 mm system calibration.

Field Installation Guidelines

• Shielding and Grounding: Insulate the coaxial ClickLoc connection using connector protectors or heat-shrink tubing. Do not allow the connector shell to contact the machine housing, because contact creates parallel ground paths that corrupt the high-frequency RF signal loop.
• Routing Constraints: Route the probe lead away from heavy power cabling. Maintain a minimum clearance of 15.2 mm from surrounding structural metals to prevent counterbore side-viewing interference from altering the target calibration.
• Thread Engagement: Ensure a minimum thread engagement of five full turns when installing the probe into the mounting bracket or machine housing to guarantee physical stability under industrial vibration profiles.
