Bently Nevada 190501-02-00-00 Velomitor CT Velocity Transducer Overview

Product Introduction

When unplanned machinery downtime threatens production targets, the Bently Nevada 190501-02-00-00 Velomitor CT Velocity Transducer provides precise vibration measurement to enable early fault detection. This rugged sensor is engineered for continuous monitoring of rotating equipment such as turbines, compressors, and pumps. Manufactured in the U.S.A., it offers a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%, ensuring accurate velocity readings across a wide frequency range.

Technical Specifications Breakdown

The 190501-02-00-00 covers a frequency response of 3.0 Hz to 900 Hz (180 to 54,000 cpm) within ±1.0 dB, with an extended range of 1.5 Hz to 1.0 kHz (90 to 60,000 cpm) within ±3.0 dB. Its output bias voltage is 10.1 Vdc ± 1.0 Vdc, and dynamic output impedance is less than 400 Ω typical. The transducer operates from -40°C to +85°C and stores from -40°C to +100°C. With a mounted resonant frequency of 9 kHz minimum and a shock limit of 5000 g pk, it withstands harsh industrial environments. The case is made of 316L stainless steel, and the connector is a 2-pin 316L stainless steel MIL-C-5015 top connector. Weight is less than 297 g (10.5 oz).

Industry Applications

This velocity transducer excels in predictive maintenance programs for critical rotating assets. For example, in a steam turbine train, continuous vibration monitoring using the 190501-02-00-00 helps detect bearing wear or imbalance before catastrophic failure occurs. In large centrifugal compressors, its wide frequency response captures both low-speed and high-speed vibration signatures, enabling operators to schedule repairs during planned outages rather than emergency shutdowns. The transducer's internal electronics are isolated from the case, reducing ground loop issues in electrically noisy environments.

Installation & Setup Guidance

Proper mounting is essential for accurate readings. The 190501-02-00-00 uses a stud mounting hardware option (3/8-in 24 to 1/2-in 20) with a recommended mounting torque of 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf). The mounting surface must be at least 33 mm diameter (1.3 in). Polarity is defined: Pin A goes positive with respect to Pin B when velocity is from base to top. The transducer can be installed at any orientation. Maximum cable length is 305 metres (1,000 ft.) using cable part number 02173006 without signal degradation.

Maintenance & Reliability

Routine inspection of the transducer and its cabling ensures long-term reliability. Check for physical damage, corrosion on the 316L stainless steel case, and secure mounting. The humidity limit is 100% condensing (non-submerged), making it suitable for washdown areas. Magnetic field susceptibility is less than 0.0068 mm/s/gauss (0.268 mil/s/gauss) at 50 gauss, 50-60 Hz, so it performs reliably near motors and generators. Base strain sensitivity is 0.43 mm/s/μstrain (0.017 in/s/μstrain), minimizing false readings from structural flexing.

Selection Guide & Purchasing Advice

Before ordering the 190501-02-00-00, verify your required agency approvals. This specific option (00) carries no approvals. For intrinsically safe installations, consider options 01 through 04 which offer Ex ia IIC T4 and AEx ia IIC T4 certifications. Always confirm compatibility with your existing Bently Nevada monitoring system. For complete technical specifications and current availability, contact BluePLC Industrial.
