Description

Designed for critical vibration and position monitoring in confined machinery spaces, the Bently Nevada 330878-90-00 serves as an essential component of the 3300 XL NSv Proximity Transducer System. This high-precision Proximitor Sensor processes radio frequency (RF) signals generated by a proximity probe to deliver a voltage output directly proportional to the gap distance between the probe tip and the target. It is engineered specifically for applications requiring tight installation clearances, such as centrifugal air compressors, refrigeration compressors, and high-speed turbomachinery.

The 330878-90-00-2 configuration features a 9.0-meter system length design, optimized for panel mounting within centralized control cabinets. This unit provides stable dynamic and static measurements, ensuring seamless interfacing with Bently Nevada monitoring systems and other machinery protection platforms. By omitting agency approvals, this specific variant offers a highly cost-effective solution for non-hazardous industrial environments.

Features

Specifically calibrated for the 3300 NSv proximity probe and extension cable series.
Provides excellent signal stability and linearity in tight installation environments.
Integrated 9.0-meter system length calibration.
Panel-mount housing design for convenient enclosure installation.
Robust electrical isolation and shielding to prevent signal degradation.

Applications

Centrifugal air compressors and turbochargers
Refrigeration and process gas compressors
High-speed micro-turbines and generators
Industrial pumps and cooling tower fans
General machinery shaft vibration and thrust position monitoring

Installation Guidelines

To ensure optimal signal integrity and mechanical stability, adhere to the following installation practices:

Mount the Proximitor Sensor on a clean, flat surface inside an industrial enclosure rated for the local environment.
Verify that the total physical length of the connected proximity probe and extension cable exactly equals 9.0 meters to match the sensor's internal calibration.
Avoid routing sensor signal lines adjacent to high-voltage power cables or variable frequency drive (VFD) output cables to prevent electromagnetic interference.
Ensure all terminal connections are secured tightly according to the manufacturer's recommended torque specifications.

FAQ
