Bently Nevada 190501-11-00-CN Velomitor CT Velocity Transducer Overview

Product Introduction

When unplanned downtime threatens production targets, the Bently Nevada 190501-11-00-CN Velomitor CT Velocity Transducer delivers reliable vibration monitoring to protect critical rotating machinery. This transducer converts mechanical velocity into an electrical signal, enabling early detection of bearing wear, imbalance, and misalignment. Designed for harsh industrial environments, it offers a cost-effective path to predictive maintenance and extended asset life.

Technical Specifications Breakdown

The 190501-11-00-CN provides a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%, ensuring accurate vibration measurement across a wide range of machinery. Its frequency response spans 3.0 Hz to 900 Hz (180 to 54,000 cpm) ±1.0 dB, with an extended range of 1.5 Hz to 1.0 kHz (90 to 60,000 cpm) ±3.0 dB. This broad coverage captures both low-speed and high-speed vibration events, reducing the need for multiple sensor types and lowering overall system cost.

The transducer operates from -40°C to +85°C (-40°F to +185°F) and stores safely from -40°C to +100°C (-40°F to +212°F), ensuring stable performance in extreme conditions. With a mounted resonant frequency of 9 kHz minimum and amplitude linearity of ±2% to 63.5 mm/s pk (2.5 in/s pk), it delivers consistent data that supports accurate trend analysis and reduces false alarms. The output bias voltage of 10.1 Vdc ± 1.0 Vdc (Pin A referenced to Pin B) simplifies integration with standard monitoring systems, minimizing installation complexity and cost.

Industry Applications

In the oil and gas sector, the 190501-11-00-CN monitors pumps, compressors, and turbines to detect early signs of mechanical degradation. By catching faults before catastrophic failure, plants avoid costly emergency repairs and production losses. In power generation, it tracks vibration in steam and gas turbines, supporting condition-based maintenance schedules that optimize spare parts inventory and labor allocation. For manufacturing facilities, the transducer helps maintain uptime on critical fans and motors, directly improving overall equipment effectiveness (OEE) and reducing total cost of ownership.

Installation & Setup Guidance

Mount the 190501-11-00-CN using the provided 3/8-in 24 to 1/4-in 28 plate stud hardware, applying a torque of 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf). The MIL-C-5015 connection interface ensures a secure, weather-resistant link. Position the transducer in any orientation to suit your machinery layout. Use cable part number 02173006 up to 305 metres (1,000 ft.) without signal degradation, keeping wiring away from high-current sources to maintain signal integrity. Verify the output bias voltage at installation to confirm proper operation and baseline readings.

Maintenance & Reliability

The 190501-11-00-CN features a 316L stainless steel case and connector, offering excellent corrosion resistance in humid or chemically aggressive environments. Its internal electronics are isolated from the case, reducing ground loop issues and improving measurement accuracy. With a shock limit of 5000 g pk and humidity tolerance up to 100% condensing (non-submerged), the transducer withstands demanding field conditions. Periodic inspection of the mounting torque and cable condition ensures long-term reliability. By reducing unexpected failures, this transducer lowers maintenance costs and extends the interval between overhauls.

Selection Guide & Purchasing Advice

Before ordering the Bently Nevada 190501-11-00-CN, verify that your monitoring system accepts a velocity input with the specified sensitivity and bias voltage.
