Bently Nevada 330180-90-05 3300 XL Proximitor Sensor

Bently Nevada 330180-90-05 3300 XL Proximitor Sensor

The Bently Nevada 330180-90-05, also cataloged as the 3300 XL Proximitor Sensor 5/8 mm, operates as a dedicated hardware component for signal conditioning within TSI (Turbomachinery Supervisory Instrumentation) systems.

Suffix Breakdown & Model Matrix

Hardware Specifications

Mechanical Monitoring & TSI Integration

The 3300 XL sensor processes high-frequency signals for eddy-current probe scaling, providing linear output for displacement and vibration monitoring. Precise gap voltage validation to the -10 VDC target is required to ensure consistent measurement linearity across the full operating range. The sensor is designed for rotor dynamics applications, utilizing internal circuit architecture to provide cross-talk suppression when multiple sensors are mounted in high-density rack environments. This component maintains complete interchangeability with 3300 XL probes and extension cables, ensuring system accuracy without requiring individual component bench calibration.

Frequently Asked Questions

Q: Can this 9.0 meter Proximitor Sensor be used with a 5-meter extension cable?

A: No. The system is calibrated for a specific total length of 9.0 meters. Substituting components with different lengths will introduce measurement errors due to signal attenuation and capacitance variations.

Q: Does this Proximitor support backward compatibility with non-XL 3300 series probes?

A: Yes. The 3300 XL Proximitor Sensor is compatible with both 3300 XL and standard 3300 series 5 mm and 8 mm probe components, facilitating system upgrades.

Field Installation Guidelines

• Mounting: The panel-mount configuration requires a secure, grounded metallic chassis. Ensure the mounting screws are tightened to provide a low-resistance path to the rack ground.
• Wiring: Connect the probe and extension cable using the ClickLoc coaxial connectors. Do not overtighten the connectors to avoid damaging the internal center pins.
• EMI Protection: Route coaxial cabling away from high-current power cables and motor leads. Use dedicated conduits to prevent electromagnetic interference (EMI) from inducing noise into the sensor signal.
• Gap Voltage Check: Upon initial power-up, measure the output gap voltage at the Proximitor terminal block. Verify that the voltage corresponds to the physical gap between the probe tip and the target as per the machinery specifications.
