Description Reviews

The Bently Nevada 330850-50-CN, also cataloged as the 330850 25 mm Proximitor Sensor, operates as a dedicated hardware component for eddy-current transducer signal conditioning within machine monitoring systems. This unit interfaces with 25 mm proximity probes to translate displacement data into proportional voltage signals for monitoring shaft position and rotative motion.

Eddy-Current Probe Scaling and Validation

The 330850 Proximitor sensor is calibrated to provide a linear voltage output relative to the probe-to-target gap when paired with a matching 25 mm transducer system. For system verification, users must conduct gap voltage validation at the nominal mechanical center, targeting -10 VDC to confirm correct probe scaling. The integrity of the rotor dynamics data relies on the consistency of the 5.0 metre system length, which accounts for the impedance of the probe, extension cable, and internal sensor circuitry. Cross-talk suppression is maintained by internal signal shielding, preventing interference in multi-channel installations where closely spaced probes may otherwise induce signal ghosting.

Frequently Asked Questions

Q: Can the 330850-50-CN be utilized in a system that requires a different system length?

A: No. The Proximitor sensor is impedance-matched to the designated 5.0 metre system length. Utilizing a different cable length will induce signal attenuation and non-linearity, rendering the monitoring data invalid.

Q: Is this sensor compatible with non-Bently Nevada 25 mm probes?

A: No. The 330850 sensor is calibrated specifically for the 3300 XL 25 mm probe series. Mismatched probe components will result in improper gap voltage ranges and incorrect sensitivity output.

Field Installation Guidelines

Ensure the mounting surface for the panel mount configuration is grounded to the instrument common to provide a stable reference for the sensor shield.
Maintain a minimum separation of 50 mm between the coaxial signal cables and any high-frequency power lines to prevent EMI injection.
Tighten the coaxial connector couplings to finger-tight, followed by a 1/4 turn to ensure a secure, low-resistance connection without damaging the center pin.
Verify the probe-to-target gap using a precise feeler gauge or micrometer before applying power to ensure the output signal remains within the linear operating range.
Inspect the cable transition areas for sharp bends; maintain a minimum bend radius of 50 mm to preserve the coaxial cable characteristic impedance.
