Description

Technical Overview

The Bently Nevada 3500/15 114M5330-01 Low Voltage DC Proximitor Interface Module (PIM) is a critical signal conditioning component within the industry-leading 3500 Machinery Protection System. Engineered for high-reliability continuous monitoring of rotating equipment, this PIM converts raw eddy-current probe signals into precise, noise-immune DC voltage outputs compatible with system controllers and data acquisition units. Its low-voltage DC architecture ensures stable operation in electrically noisy industrial environments—common in power generation, oil & gas, petrochemical, and heavy manufacturing facilities.

Designed to interface seamlessly with standard 3500 rack-mounted monitors, the 114M5330-01 supports dual-channel configuration per module, enabling simultaneous monitoring of key parameters such as shaft vibration, axial position, or differential expansion. The module features advanced filtering, automatic calibration support, and built-in diagnostics—including LED status indicators and digital communication via the 3500 backplane—to simplify commissioning, troubleshooting, and predictive maintenance workflows. Its robust construction meets stringent IEC 61000-4 electromagnetic compatibility (EMC) standards and operates reliably across extended temperature ranges (-30°C to +70°C), making it ideal for harsh, mission-critical applications where uptime and measurement integrity are non-negotiable.

Key Features

• Dual-Channel Signal Conditioning: Processes two independent eddy-current probe inputs with precision linearization and temperature compensation.
• Low-Voltage DC Output: Delivers stable 4–20 mA or ±10 VDC outputs (field-selectable) with high signal-to-noise ratio and minimal drift.
• Integrated Diagnostics & Status Monitoring: Real-time health checks, fault logging, and LED-based visual indicators for rapid on-site verification.
• Backplane Communication Ready: Fully compatible with Bently Nevada 3500 system firmware and configuration software (System 1™) for centralized setup and trending.
• Industrial-Rated Construction: Conforms to UL, CSA, and CE safety standards; designed for continuous operation in high-vibration, high-EMI environments.
