Description

Configured for precise physical/electrical execution in 3500 Machinery Protection System networks, the Bently Nevada 330103-08-13-10-02-CN (330103 Proximity Probe) provides direct physical/electrical execution. Consequently, the sensor monitors dynamic parameters of rotating shafts without physical contact, transmitting raw target displacement metrics directly into machinery monitoring platforms.

Hardware Specifications

Gap Voltage Validation and Eddy-Current Probe Scaling

Field technicians execute gap voltage validation to position the probe tip within the linear range of the transducer loop. Specifically, an optimum mechanical calibration achieves a -10 VDC target voltage at the physical midpoint of the linear scale. Furthermore, eddy-current probe scaling requires strict matching with the specific target material chemistry to minimize errors in rotor dynamics monitoring. Therefore, the system suppresses cross-talk between adjacent probe tips through proper physical separation and the deployment of integrated coaxial shielding.

Frequently Asked Questions

Q: How do technicians verify the operational linear range of the 330103 probe during field setup?

A: Technicians apply a static calibration using a spindle micrometer. They measure the voltage output across the gap to confirm a uniform scale factor of 7.87 V/mm.

Q: What protection does the -02 connector option provide for the terminal coupling?

A: The -02 suffix adds a pre-installed connector protector over the miniature coaxial ClickLoc junction. Consequently, this sleeve reinforces mechanical rigidity and isolates the physical connection point from fluid ingress.

Field Installation Guidelines

First, thread the probe into the mounting bracket using standard 3/8-24 UNF parameters. Next, establish a minimum clearance to avoid structural interference with the unthreaded case section. Additionally, execute a full 5-thread engagement to lock the probe securely. Finally, connect the mini-coaxial connector to the extension cable and slide the connector protector into place to block oil contamination.
