Description

Technical Overview

The Bently Nevada 330980-70-00 is a high-precision NSv Proximity Sensor engineered for mission-critical machinery monitoring in industrial automation, power generation, oil & gas, and heavy manufacturing environments. Designed to deliver exceptional reliability under extreme operating conditions—including high temperatures, vibration, and electromagnetic interference—the sensor enables continuous, non-contact measurement of shaft displacement, vibration, and rotational speed with micron-level resolution. Its advanced eddy-current technology ensures stable output across varying gap distances and surface materials, making it ideal for integration into asset condition monitoring and predictive maintenance systems.

This NSv-series sensor complies with API 670 (4th Edition) and ISO 10816 standards for machinery protection systems, supporting seamless interoperability with Bently Nevada 3500/4000 series monitors and System 1™ diagnostic software. The 330980-70-00 features optimized thermal stability and low-noise signal conditioning, minimizing drift over time and reducing false alarms in critical protection applications. Its rugged stainless-steel housing and hermetically sealed construction provide IP67-rated ingress protection, ensuring long-term performance in harsh, washdown-prone or explosive atmospheres when used with appropriate barriers.

Key Features

• High-Accuracy Eddy-Current Sensing: Delivers linear, repeatable measurements from 0.25 mm to 2.5 mm sensing range with ±1% full-scale linearity.
• Ruggedized Industrial Design: 316 stainless-steel probe body and integral cable with Teflon® insulation for resistance to corrosion, abrasion, and high-temperature exposure (up to +125°C).
