Bently Nevada 190501-10-00-00 Velomitor CT Velocity Transducer

Product Overview

The Bently Nevada 190501-10-00-00 serves as a high-precision Velomitor CT (Cooling Tower) transducer specifically engineered for monitoring the vibration of machinery in cooling towers and other humid industrial environments. This piezoelectric velocity sensor converts vibration signals into a proportional voltage output, allowing maintenance professionals to detect mechanical imbalances, misalignment, or bearing wear before catastrophic failures occur. By utilizing solid-state electronics, the transducer eliminates moving parts that typically wear out in traditional velocity sensors, thereby ensuring a significantly longer service life and higher measurement stability.

Technical Performance and Features

• Vibration Detection CapabilitiesThe unit provides a standard sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%, which allows for precise tracking of velocity-based vibration levels. It operates across a broad frequency range from 1.5 Hz to 1.0 kHz, capturing both low-speed structural oscillations and higher-frequency mechanical faults.
• Environmental ResilienceConstructed with a 316L stainless steel housing, the 190501-10-00-00 offers superior resistance to corrosion and moisture. It maintains operational integrity within a temperature range of -52°C to +121°C, making it an ideal choice for the extreme temperature fluctuations found in cooling tower applications.
• Signal Integrity and InstallationThe transducer utilizes a 2-pin Mil-spec connector or integral cable options to facilitate secure electrical connections. Furthermore, its internal shielding prevents electromagnetic interference from distorting the signal, which is vital when cables are routed near heavy industrial motors or power lines.
• Simplified IntegrationThis transducer integrates seamlessly with Bently Nevada 3500 and 2300 monitoring systems. Because the device functions as a self-generating sensor that does not require external bias power for the sensing element itself, it simplifies the wiring architecture of the condition monitoring network.
