Hardware Specifications

Rotor Dynamics and Signal Conditioning

Consequently, the 330130-080-12-05 cable executes exact electrical impedance matching between the proximity probe tip and the Proximitor sensor. During dynamic shaft rotation, the FluidLoc construction prevents internal oil or gas migration through the cable core, thereby maintaining system stability under high pressure-gradient transitions. Meanwhile, the coaxial shield configuration provides strict cross-talk suppression between closely packed adjacent sensor runs. This targeted shielding configuration eliminates external radio frequency and electromagnetic interference, isolating the low-voltage telemetry to yield accurate gap voltage validation toward the target -10 VDC baseline for rotor dynamics diagnostics.

Frequently Asked Questions

Q: How does the FluidLoc option change the physical behavior of this cable in processing environments?

A: Because the FluidLoc design features internal blocking material within the cable layers, it explicitly stops lubricating oils or cooling fluids from leaking out of the machine casing through the cable interior. Consequently, this design protects external terminal blocks from chemical contamination without altering electrical core parameters.

Q: Can field technicians pair this 8.0-meter extension cable with any 3300 XL probe configuration?

A: No, because the Proximitor sensor requires a calibrated total electrical system length of 9.0 meters, technicians must pair this 8.0-meter extension cable exclusively with a 1.0-meter proximity probe. Incorrect mixing of lengths disrupts system tuning, which subsequently shifts the nominal scale factor.

Field Installation Guidelines

• Mechanical Connection: First, wipe the miniature coaxial ClickLoc connectors with a lint-free cloth to remove grease. Next, push the male and female ends together firmly until the mechanical lock snaps completely into position. Finally, slide the connector protector sleeve over the interface to ensure a sealed connection.
• Transducer Shielding: Terminate the outer coaxial shield layer exclusively at the Proximitor sensor side grounding strip. Conversely, never ground the shield at the machine casing or probe housing end, as single-point grounding is mandatory to prevent circulating ground loops from introducing noise.
• Cable Routing: Route the extension line inside dedicated metal conduit or covered cable trays. Furthermore, isolate these measurement paths from high-voltage AC motor lines or variable frequency drive paths to suppress inductive noise coupling.
