Bently Nevada 190501-11-00-04 Velomitor CT Velocity Transducer Overview

Product Introduction

When machinery vibration threatens uptime and safety, the Bently Nevada 190501-11-00-04 Velomitor CT Velocity Transducer delivers precise, reliable measurements. This industrial-grade sensor is designed for continuous monitoring in harsh environments, converting mechanical velocity into an electrical signal for analysis. Manufactured in the U.S.A., it combines rugged construction with proven Bently Nevada engineering.

Technical Specifications Breakdown

The 190501-11-00-04 provides a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%, ensuring accurate velocity readings across its operating range. Its frequency response covers 3.0 Hz to 900 Hz (180 to 54,000 cpm) within ±1.0 dB, extending to 1.5 Hz to 1.0 kHz (90 to 60,000 cpm) at ±3.0 dB. The transducer maintains amplitude linearity within ±2% up to 63.5 mm/s pk (2.5 in/s pk). Output bias voltage is 10.1 Vdc ± 1.0 Vdc, with dynamic output impedance below 400 Ω typical. Broadband noise is just 0.229 mm/s (0.009 in/s) pk. The mounted resonant frequency is 9 kHz minimum (stud mounted, except quick disconnect).

Industry Applications

This velocity transducer excels in rotating machinery monitoring, such as turbines, compressors, and pumps. In oil and gas facilities, its ATEX/IECEx/CSA approvals (Class I, Division 1, Zone 0/1) allow safe operation in explosive atmospheres. Power generation plants benefit from its wide temperature range (-40°C to +85°C operating) and shock limit of 5000 g pk, ensuring reliable data in demanding conditions.

Installation & Setup Guidance

Mount the 190501-11-00-04 using the included plate stud (3/8-in 24 to 1/4-in 28) with 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. Polarity is defined: Pin A goes positive with respect to Pin B when velocity is from base to top. Any orientation is acceptable, and the internal electronics are isolated from the case to prevent ground loops. Maximum cable length is 305 metres (1,000 ft.) with part number 02173006 without signal degradation.

Maintenance & Reliability

With a 316L stainless steel case and 100% condensing humidity tolerance (non-submerged), this transducer resists corrosion and moisture. The internal electronics remain isolated from the case, reducing maintenance needs. Periodic inspection of the mounting surface and cable integrity ensures long-term reliability. Its magnetic field susceptibility is below 0.0068 mm/s/gauss (0.268 mil/s/gauss) at 50 gauss, 50-60 Hz, minimizing interference in electrically noisy environments.

Selection Guide & Purchasing Advice

Before ordering the 190501-11-00-04, verify compatibility with your monitoring system and confirm the agency approval option (04 provides CSA/NRTL/C, ATEX/IECEx/CSA). The transducer weighs 0.297 kg (10.5 oz.) and has a height of 82 mm (3.2 in). For complete technical specifications and current availability, contact BluePLC Industrial.
