Bently Nevada 190501-13-00-CN Velomitor CT Velocity Transducer Overview

Product Introduction

When machinery vibration threatens uptime and reliability, the Bently Nevada 190501-13-00-CN Velomitor CT Velocity Transducer delivers precise, real-time data for predictive maintenance. This velocity transducer, part of the trusted Velomitor CT series, converts mechanical vibration into an electrical signal proportional to velocity. With a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%, it provides accurate measurements essential for protecting rotating equipment like turbines, compressors, and pumps. Manufactured in the U.S.A., this model features a quick disconnect stud mounting option and a MIL-C-5015 connection interface, ensuring robust performance in demanding industrial environments.

Technical Specifications Breakdown

The 190501-13-00-CN offers a frequency response of 3.0 Hz to 900 Hz (180 to 54,000 cpm) ±1.0 dB, extending to 1.5 Hz to 1.0 kHz (90 to 60,000 cpm) ±3.0 dB. This wide range captures both low-speed and high-speed vibration events. Temperature sensitivity varies from -8% to +5% typical over the operating temperature range of -40°C to +85°C (-40°F to +185°F). The transducer maintains amplitude linearity within ±2% up to 63.5 mm/s pk (2.5 in/s pk). Its output bias voltage is 10.1 Vdc ± 1.0 Vdc (Pin A referenced to Pin B), and dynamic output impedance is less than 400 Ω typical. The internal electronics are isolated from the case, and the maximum cable length is 305 metres (1,000 ft.) using cable part number 02173006 without signal degradation. The unit weighs 0.297 kg and has a case material of 316L stainless steel.

Industry Applications

This velocity transducer excels in continuous vibration monitoring for critical rotating machinery. In power generation, it tracks turbine shaft vibrations to prevent catastrophic failures. In oil and gas refineries, it monitors compressor and pump health, enabling condition-based maintenance that reduces unplanned downtime. Compared to piezoelectric accelerometers, the Velomitor CT provides a direct velocity output, simplifying integration with existing Bently Nevada monitoring systems. Its robust design, including a shock limit of 5000 g pk and 100% condensing humidity tolerance, makes it suitable for harsh environments.

Installation & Setup Guidance

Mount the 190501-13-00-CN using the quick disconnect stud with a mounting torque of 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf). The transducer can be mounted at any angle, offering flexibility in tight spaces. Ensure the mounting surface is clean and flat (33 mm diameter). The 2-pin 316L stainless steel MIL-C-5015 connector provides a secure, corrosion-resistant connection. For proper polarity, Pin A goes positive with respect to Pin B when velocity is from base to top. Use shielded cable (part number 02173006) up to 305 metres to maintain signal integrity.

Maintenance & Reliability

Routine inspection of the transducer and cabling is recommended to ensure reliable operation. Check for physical damage, corrosion, or loose connections, especially in high-vibration or corrosive environments. The 316L stainless steel case resists corrosion, extending service life. The transducer's internal electronics are isolated from the case, reducing ground loop issues. For long-term reliability, verify that the mounting torque remains within specification during periodic maintenance. The unit's wide operating temperature range (-40°C to +85°C) and humidity tolerance (100% condensing, non-submerged) ensure consistent performance in extreme conditions.

Selection Guide & Purchasing Advice

When selecting the 190501-13-00-CN, verify compatibility with your monitoring system's input requirements. The transducer outputs a velocity signal with a sensitivity of 3.94 mV/mm/s, which must match the input range of your data acquisition or protection system. The agency approval option "CN Country Specific" indicates region-specific certifications; confirm applicability for your location.
