Bently Nevada 190501-12-00-CN Velomitor CT Velocity Transducer Overview

What Is the Bently Nevada 190501-12-00-CN?

When unexpected machine vibrations threaten uptime, the Bently Nevada 190501-12-00-CN Velomitor CT Velocity Transducer provides accurate velocity measurements to help protect critical rotating equipment. This transducer, manufactured by Bently Nevada in the U.S.A., is designed for permanent installation in harsh industrial environments. Its rugged 316L stainless steel case and MIL-C-5015 connection interface ensure durability and reliable signal transmission.

Technical Specifications Breakdown

The 190501-12-00-CN offers a sensitivity of 3.94 mV/mm/s (100 mV/in/s) with ±5% tolerance. 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. The transducer operates over a temperature range of -40°C to +85°C (-40°F to +185°F) and can be stored from -40°C to +100°C (-40°F to +212°F). With a weight of 0.297 kg and a mounting surface diameter of 33 mm (1.3 in), it fits compact installations. The output bias voltage is 10.1 Vdc ± 1.0 Vdc, and the dynamic output impedance is less than 400 Ω typical. It can handle cable lengths up to 305 metres (1,000 ft.) using part number 02173006 without signal degradation.

Industry Applications

This velocity transducer is ideal for monitoring vibration on pumps, fans, compressors, and turbines in industries like oil and gas, power generation, and manufacturing. Its intrinsic safety approvals (Ex ia IIC T4 and AEx ia IIC T4) make it suitable for hazardous locations where explosive gases may be present. The transducer's transverse response is less than 5% of the axial sensitivity, ensuring accurate readings even in complex vibration environments.

Installation & Setup Guidance

Mount the 190501-12-00-CN using the provided plate stud 3/8-in 24 to M8x1 hardware. Apply a mounting torque of 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf). The transducer can be installed at any orientation. Ensure the mounting surface is clean and flat for optimal coupling. Connect via the MIL-C-5015 interface, observing polarity: Pin A goes positive with respect to Pin B when velocity is from base to top. For hazardous area installations, follow drawing 167536.

Maintenance & Reliability

Routine inspection of the cable and connector is recommended to maintain signal integrity. The 316L stainless steel case resists corrosion in demanding environments. The internal electronics are isolated from the case, reducing ground loop issues. With a shock limit of 5000 g pk maximum, this transducer withstands severe mechanical shocks without damage.

Selection Guide & Purchasing Advice

When ordering the 190501-12-00-CN, verify the agency approval option (CN Country Specific) matches your regional requirements.
