Description

Engineered for tight-clearance industrial machinery monitoring, the 330980-70-CN is the signal conditioning core of the Bently Nevada 3300 NSv (Narrow System vibration) Proximity Transducer System. This specialized sensor is designed to interface with 3300 NSv proximity probes and extension cables, providing accurate dynamic and static shaft measurements in setups with narrow target profiles or limited spatial access.

The 330980-70-CN Proximitor Sensor processes the high-frequency RF signal from the probe to generate a continuous voltage output directly proportional to the physical gap between the probe tip and the observed conductive target. This output signal is seamlessly compatible with Bently Nevada 3500 and 3300 monitoring systems, ensuring reliable integration into plant-wide asset protection and machinery diagnostic architectures.

Features

Optimized for small-diameter shafts and narrow-profile installation environments.
Provides highly linear static (gap) and dynamic (vibration) displacement measurements.
Excellent resistance to radio frequency interference (RFI) and electromagnetic interference (EMI).
Coaxial connector design ensures robust and reliable signal path connectivity.
Rugged physical packaging designed to withstand harsh industrial environments.

Applications

Aeroderivative gas turbines
Centrifugal and axial air compressors
Small steam turbines and high-speed pumps
Gearboxes and auxiliary machinery with restricted probe-mounting space

Installation Guidelines

Grounding: Ensure the Proximitor Sensor is mounted on a clean, dry DIN rail or mounting plate. The sensor housing must be electrically isolated from the machine ground to prevent ground loops.
Cable Protection: All coaxial connections should be wrapped with connector silicone self-fusing tape to prevent fluid intrusion and physical damage.
Wiring: Route field wiring from the Proximitor to the monitor rack using shielded twisted-pair cables. Ensure the cable shield is grounded only at the monitoring rack end.
Clearance: Maintain the specified minimum mechanical clearance around the probe tip to prevent cross-talk and side-viewing interference.

Key Features:

What is the primary application for the Bently Nevada 330980-70-CN?

The 330980-70-CN is designed for the 3300 NSv Proximity Transducer System, which is optimized for machinery with small shaft diameters or narrow target profiles, such as aeroderivative gas turbines and high-speed compressors.

What does the -CN suffix indicate on this Bently Nevada module?

The -CN suffix typically indicates that the product complies with specific regional standards and certifications required for import and installation within China and related Asia-Pacific regional markets.

Can I use the 330980-70-CN with standard 3300 XL 5mm or 8mm probes?

No. The 330980-70-CN Proximitor Sensor is calibrated specifically for the 3300 NSv (Narrow System) proximity probes and extension cables. Mixing components from different probe families will result in inaccurate measurement readings.
