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

Product Introduction

When machinery vibration threatens uptime in critical rotating equipment, the Bently Nevada 190501-11-00-CN Velomitor CT Velocity Transducer delivers precise measurement. This industrial-grade sensor, manufactured in the U.S.A., converts mechanical velocity into an electrical signal for condition monitoring systems. With a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%, it provides reliable data for predictive maintenance programs.

Technical Specifications Breakdown

Understanding the key parameters helps you match this transducer to your application. The 190501-11-00-CN offers a frequency response of 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. This range covers common machinery speeds from slow rotating drums to high-speed pumps.

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. Amplitude linearity holds within ±2% up to 63.5 mm/s pk (2.5 in/s pk). The mounted resonant frequency is 9 kHz minimum (stud mounted, except quick disconnect).

Environmental resilience is strong: operating temperature from -40°C to +85°C (-40°F to +185°F), storage from -40°C to +100°C (-40°F to +212°F). It withstands 5000 g pk shock and 100% condensing humidity. Magnetic field susceptibility is less than 0.0068 mm/s/gauss (0.268 mil/s/gauss) at 50 gauss, 50-60 Hz.

Industry Applications

This velocity transducer suits a variety of rotating machinery monitoring tasks. In steam turbine trains, its frequency response captures both low-speed shaft vibrations and higher-frequency blade pass signals. For centrifugal compressors in gas processing, the stainless steel construction resists harsh environments while the 305-meter (1,000 ft.) maximum cable length allows remote mounting from the monitoring system.

Pump monitoring in water treatment plants benefits from the transducer's wide operating temperature range and 100% humidity tolerance. The internal electronics are isolated from the case, reducing ground loop issues common in industrial settings.

Installation & Setup Guidance

Mounting the 190501-11-00-CN requires attention to surface preparation. The mounting surface must be 33 mm diameter (1.3 in diameter). Use the provided plate stud (3/8-in 24 to 1/4-in 28) and tighten to 4.5 N-m ± 0.6 N-m (40 in-lbf ± 5 in-lbf). The transducer can be mounted in any orientation. Polarity is defined: Pin A goes positive with respect to Pin B when velocity is from base to top.

For cable runs, use part number 02173006 up to 305 metres (1,000 ft.) without signal degradation. The connection uses a MIL-C-5015 2-pin 316L stainless steel connector on top.

Maintenance & Reliability

Routine inspection should verify the mounting torque remains within specification and the cable is free from damage. The 316L stainless steel case resists corrosion in most industrial atmospheres. The transducer's internal electronics are isolated from the case, reducing susceptibility to electrical noise. Periodic functional testing using a known vibration source can confirm sensitivity remains within ±5%.

Selection Guide & Purchasing Advice

Before purchasing the Bently Nevada 190501-11-00-CN, verify the agency approval option matches your site requirements. This unit carries the CN country-specific approval. For intrinsically safe installations, confirm the transducer's Ex ia IIC T4 or AEx ia IIC T4 ratings (for agency approval options 01 through 04) align with your area classification. Always install per drawing 167536 for hazardous locations.
