The Bently Nevada 330103-00-05-10-01-00 serves as the primary 330103 Proximity Sensors utilized to execute non-contact relative shaft position and dynamic vibration monitoring across 3300 XL Transducer System platforms. It emits a high-frequency radio frequency field through its polyphenylene sulfide tip to detect physical displacement variations against rotating shafts.

Eddy-Current Probe Scaling & Rotor Dynamics

The 330103-00-05-10-01-00 probe utilizes its 8 mm tip coil to maintain continuous eddy-current probe scaling at a linear 7.87 V/mm (200 mV/mil) sensitivity when tied to a matched extension cable and 3300 XL Proximitor sensor. Proper mechanical installation requires gap voltage validation targeting -10 VDC at nominal shaft center position. This setting maximizes linear dynamic range for peak-to-peak vibration excursions and promotes cross-talk suppression between closely spaced probes monitoring complex rotor dynamics.

Frequently Asked Questions

Q: What function does the integrated Viton O-ring provide in this probe assembly?

A: The Viton O-ring seals differential pressure between the probe tip and the stainless steel case body, preventing process fluid leakage through the internal probe casing.

Q: Why does option -01 include a factory connector protector?

A: The connector protector seals the miniature coaxial ClickLoc connection from oil, moisture, and debris, while isolating the coaxial shield from physical grounding against the machine chassis.

Q: Can this 1.0-meter probe cable (-10 option) connect directly to a 5.0-meter calibrated Proximitor sensor?

A: No, a 1.0-meter probe requires a 4.0-meter extension cable to complete the 5.0-meter total electrical system length calibrated for the Proximitor sensor.

Field Installation Guidelines

  1. Clean and inspect the 3/8-24 UNF threaded port for thread debris prior to inserting the probe assembly.
  2. Hand-thread the 50 mm probe into the housing bracket until the probe tip approaches the target shaft surface.
  3. Wire the cable to the matching 3300 XL system and measure DC voltage output; adjust insertion depth until achieving the -10 VDC target gap voltage baseline.
  4. Tighten the probe locknut against the mounting bracket face to the proper torque limit without twisting the lead cable.
  5. Secure the ClickLoc coaxial connector to the extension cable and slide the connector protector over the joint to ensure electrical isolation from ground potential loops.
