Description

Technical Overview

The Bently Nevada 190501-12-00-01 Velomitor CT Velocity Transducer is a high-reliability, IEPE-compatible industrial vibration sensor engineered for continuous condition monitoring of rotating machinery in demanding plant environments. Designed to deliver accurate velocity measurements across a broad frequency range (4.5 Hz to 1 kHz), this transducer converts mechanical vibration into a proportional electrical output signal—enabling precise detection of early-stage bearing wear, misalignment, imbalance, and other critical failure modes. Its robust construction features a stainless steel housing, integral cable, and hermetically sealed electronics, ensuring long-term stability and resistance to moisture, oil, and electromagnetic interference.

Unlike accelerometers requiring external signal conditioning, the Velomitor CT integrates built-in charge-to-voltage conversion and constant-current power regulation, simplifying system integration with standard 4–20 mA or ±5 V DC data acquisition hardware—including Bently Nevada System 1®, 3500/40M, and third-party PLCs and DCS platforms. The transducer’s low-noise design and optimized damping characteristics minimize phase shift and resonance artifacts, supporting reliable trend analysis and automated alarm logic in predictive maintenance programs. Widely deployed in power generation, oil & gas, pulp & paper, and water/wastewater infrastructure, the 190501-12-00-01 meets stringent API 670 (4th Edition) requirements for machinery protection systems.

Key Features

• IEPE-Compatible Output: Delivers low-impedance, noise-immune velocity signals compatible with industry-standard monitoring systems without external amplification.
• Ruggedized Industrial Design: Stainless steel housing (IP67 rated), integral 10-ft (3 m) shielded cable, and wide operating temperature range (–40°C to +125°C).
• Optimized Frequency Response: Flat velocity response from 4.5 Hz to 1 kHz (±5%), enabling detection of both low-frequency structural issues and mid-frequency bearing faults.
• Self-Diagnostics Ready: Supports loop-powered diagnostics and seamless integration with Bently Nevada’s Machinery Health™ software suite for real-time health assessment.
• Plug-and-Play Installation: Standard 10-32 UNF mounting thread and consistent output scaling (500 mV/in/sec or 19.7 mV/mm/s) reduce commissioning time and configuration errors.
