Bently Nevada 190501-01-00-CN Velomitor CT Velocity Transducer Overview

Product Introduction

When machinery vibration threatens uptime and equipment life, the Bently Nevada 190501-01-00-CN Velomitor CT Velocity Transducer delivers precise, reliable measurements for condition monitoring. This sensor is engineered for industrial environments where accurate velocity data is critical to predictive maintenance programs. Manufactured in the U.S.A., the 190501-01-00-CN is part of Bently Nevada's trusted transducer family, offering a robust solution for rotating machinery protection.

Technical Specifications Breakdown

The 190501-01-00-CN provides a sensitivity of 3.94 mV/mm/s (100 mV/in/s) with ±5% tolerance, ensuring consistent output for vibration analysis. Its frequency response spans 3.0 Hz to 900 Hz (180 to 54,000 cpm) within ±1.0 dB, and extends from 1.5 Hz to 1.0 kHz (90 to 60,000 cpm) within ±3.0 dB, covering a wide range of machine speeds. The transducer operates reliably across an ambient temperature range of -40°C to +85°C (-40°F to +185°F), with storage capability from -40°C to +100°C (-40°F to +212°F). Output bias voltage is 10.1 Vdc ± 1.0 Vdc, referenced from Pin A to Pin B, and dynamic output impedance is less than 400 Ω typical. The mounted resonant frequency is a minimum of 9 kHz when stud mounted (excluding quick disconnect). These specifications make the 190501-01-00-CN suitable for demanding industrial applications.

Industry Applications

In power generation, petrochemical, and heavy manufacturing plants, the 190501-01-00-CN monitors critical rotating assets such as turbines, compressors, and pumps. Its ability to detect velocity changes with high fidelity helps operators identify bearing wear, imbalance, or misalignment early. The transducer's robust 316L stainless steel case and MIL-C-5015 connector ensure durability in harsh environments, including areas with high humidity (100% condensing, non-submerged) and magnetic field susceptibility below 0.0068 mm/s/gauss. This makes it an ideal choice for continuous vibration monitoring in both hazardous and non-hazardous locations.

Installation & Setup Guidance

Mount the 190501-01-00-CN using the included stud mounting hardware (3/8-in 24 to 3/8-in 24) with a torque of 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf). The transducer can be installed at any orientation, and polarity is defined: Pin A goes positive with respect to Pin B when velocity is directed from the base to the top of the transducer. For optimal signal integrity, use cable part number 02173006 up to 305 meters (1,000 ft.) without signal degradation. Ensure the mounting surface is clean and flat (33 mm diameter minimum) to maintain accuracy. The internal electronics are isolated from the case, reducing ground loop issues.

Maintenance & Reliability

Regular inspection of the transducer and its cable connections helps maintain measurement accuracy. Check for physical damage to the 316L stainless steel case and connector, especially in corrosive environments. The transducer's shock limit of 5000 g pk ensures resilience against occasional impacts. For long-term reliability, verify that the mounting torque remains within specification and that the cable is not subjected to excessive bending or strain. Routine calibration checks against the sensitivity specification (3.94 mV/mm/s ±5%) are recommended as part of a comprehensive maintenance program.

Selection Guide & Purchasing Advice

When selecting the 190501-01-00-CN, verify that your application requires a velocity transducer with the specified frequency response and sensitivity. Ensure compatibility with your monitoring system's input requirements, particularly the output bias voltage of 10.1 Vdc. The Country Specific (CN) agency approval option indicates suitability for certain regional standards.
