Description

Technical Overview

The Bently Nevada 3100S2-Z2 Side Exit Sensor (AS3100S2-Z2) is a high-reliability proximity transducer engineered for continuous, non-contact vibration and position monitoring in critical rotating machinery applications. Designed for integration into Bently Nevada’s 3300 XL and 3500 asset protection systems, this sensor delivers exceptional signal fidelity, thermal stability, and electromagnetic interference (EMI) immunity—essential for demanding environments such as power generation, oil & gas refineries, and large-scale industrial compressors.

Featuring a robust stainless steel housing and side-exit cable configuration, the 3100S2-Z2 enables streamlined installation in space-constrained mechanical setups where axial cable routing is impractical. Its advanced eddy-current sensing technology ensures precise measurement of shaft displacement, runout, and vibration with sub-micron resolution, supporting predictive maintenance strategies and real-time machine health assessment. The sensor complies with API RP 670 (4th Edition) and meets stringent IEC 61508 SIL 2 functional safety requirements when used within certified system architectures.

Key Features

• Side-Exit Cable Design: Optimized for tight mechanical clearances—reduces cable stress and simplifies mounting on bearing housings and pedestal-mounted machinery.
• High-Temperature Stability: Operates reliably from –30 °C to +125 °C ambient, with minimal sensitivity drift across temperature gradients typical in turbine and motor applications.
• IEC 61000-4 Compliant EMI Immunity: Resists electrical noise from VFDs, switchgear, and arc welding—ensuring signal integrity in electrically harsh plant environments.
• Field-Replaceable Probe & Cable Assembly: Modular construction allows quick maintenance without system recalibration or downtime.
• Compatible with 3300 XL and 3500 Monitoring Systems: Seamless integration with Bently Nevada’s industry-standard condition monitoring platforms for unified data acquisition and alarm management.
