Product Overview
When machinery vibration threatens uptime, the Bently Nevada 190501-10-00-CN Velomitor CT Velocity Transducer delivers precise measurements you can trust. This rugged sensor is designed for continuous monitoring in harsh industrial environments, providing essential data to prevent unexpected failures and reduce maintenance costs.
Technical Specifications Breakdown
Sensitivity and Frequency Response
The 190501-10-00-CN offers a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%, ensuring accurate velocity readings across its operating range. 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 wide bandwidth captures both low-speed and high-speed vibration events.
Environmental Durability
Operating reliably from -40°C to +85°C (-40°F to +185°F) and storing from -40°C to +100°C (-40°F to +212°F), this transducer withstands extreme conditions. It handles 100% condensing humidity and survives shock limits up to 5000 g pk, making it suitable for demanding applications like turbines and compressors.
Mechanical Construction
Built with a 316L stainless steel case and a 2-pin 316L stainless steel MIL-C-5015 top connector, the 190501-10-00-CN resists corrosion and mechanical stress. It weighs less than 297 g (10.5 oz.) and mounts on a 33 mm diameter surface with a height of 82 mm (3.2 in). The mounting torque is specified at 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf).
Industry Applications
Rotating Machinery Monitoring
In pumps, motors, and fans, the 190501-10-00-CN detects early signs of bearing wear or imbalance. Its transverse response of less than 5% of axial sensitivity ensures accurate readings even when vibrations come from multiple directions.
Turbine and Compressor Protection
For critical assets like steam turbines or centrifugal compressors, this transducer provides reliable data for predictive maintenance. The output bias voltage of 10.1 Vdc ± 1.0 Vdc (Pin A referenced to Pin B) simplifies integration with monitoring systems.
Installation & Setup Guidance
Mount the 190501-10-00-CN on a clean, flat surface using the provided plate stud M6x1 to M6x1 with 3/8-in 24 adapter. Apply the specified mounting torque of 4.5 N-m ± 0.6 N-m to ensure proper coupling. The transducer can be installed at any orientation, and the MIL-C-5015 connection interface simplifies wiring. Polarity is defined: Pin A goes positive with respect to Pin B when velocity is from base to top.
Maintenance & Reliability
Regular inspection of the mounting surface and connector integrity helps maintain accuracy. The internal electronics are isolated from the case, reducing ground loop issues. With a maximum cable length of 305 metres (1,000 ft.) using part number 02173006, you can place monitoring equipment at a safe distance without signal degradation. This design minimizes downtime and extends service intervals.
Selection Guide & Purchasing Advice
Before ordering, verify that the 190501-10-00-CN matches your application's vibration range and environmental conditions. The agency approval option CN is country-specific, so confirm local requirements. SpareTechPLC stocks this Bently Nevada transducer and can assist with compatibility checks and availability.
