Product Overview
When machinery vibration threatens uptime, the Bently Nevada 190501-19-00-CN Velomitor CT Velocity Transducer delivers precise, reliable measurements. This industrial-grade sensor converts mechanical velocity into an electrical signal, enabling early detection of rotating equipment faults. Designed for harsh environments, it provides consistent performance across a wide temperature range.
Technical Specifications
The 190501-19-00-CN offers a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%, ensuring accurate vibration readings. 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. The output bias voltage is 10.1 Vdc ± 1.0 Vdc, referenced from Pin A to Pin B. Dynamic output impedance is less than 400 Ω typical, and broadband noise is just 0.229 mm/s (0.009 in/s) pk. The transducer withstands operating temperatures from -40°C to +85°C (-40°F to +185°F) and storage temperatures from -40°C to +100°C (-40°F to +212°F).
Industry Applications
This velocity transducer excels in monitoring pumps, compressors, fans, and turbines. In a petrochemical plant, its 3.94 mV/mm/s sensitivity captures subtle vibration changes that indicate bearing wear. The wide frequency response covers both low-speed and high-speed machinery, making it versatile for various rotating assets. Its 316L stainless steel case and 100% condensing humidity tolerance suit offshore and humid environments.
Installation & Setup Guidance
Mount the 190501-19-00-CN in any orientation using the provided 3/8-in 24 to 1/4-in 18 NPT adapter. Apply a mounting torque of 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf). The MIL-C-5015 connection interface simplifies wiring. Pin A goes positive with respect to Pin B when velocity is from base to top. Maximum cable length is 305 metres (1,000 ft.) with cable part number 02173006, ensuring signal integrity over long runs.
Maintenance & Reliability
Routine inspection of the transducer and cable connections helps maintain measurement accuracy. The internal electronics are isolated from the case, reducing ground loop issues. With a shock limit of 5000 g pk, the sensor withstands occasional impacts. Verify the mounting surface is clean and flat to achieve the specified mounted resonant frequency of 9 kHz minimum.
