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

Product Introduction

When machinery vibration threatens uptime and safety, the Bently Nevada 190501-04-00-CN Velomitor CT Velocity Transducer delivers precise, reliable measurements. This transducer is engineered for continuous monitoring in harsh industrial environments, converting mechanical velocity into an electrical signal for analysis. Manufactured by Bently Nevada, a trusted name in condition monitoring, the 190501-04-00-CN is built to withstand demanding conditions while providing accurate data for predictive maintenance programs.

Technical Specifications Breakdown

The 190501-04-00-CN offers a sensitivity of 3.94 mV/mm/s (100 mV/in/s) with ±5% tolerance, ensuring consistent output for velocity measurements. Its frequency response spans 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, covering a wide range of rotating machinery speeds. The transducer features an output bias voltage of 10.1 Vdc ± 1.0 Vdc (Pin A referenced to Pin B) and a dynamic output impedance of <400 Ω typical. It operates reliably across an ambient 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). The 316L stainless steel case and connector provide excellent corrosion resistance, while the mounting hardware option includes a Stud M6x1 with 3/8-in 24 adapter. The transducer uses a MIL-C-5015 connection interface and weighs 0.297 kg.

Industry Applications

The 190501-04-00-CN is ideal for vibration monitoring in turbines, compressors, pumps, and fans across oil and gas, power generation, and manufacturing sectors. Its wide frequency response and robust construction make it suitable for both slow-speed and high-speed rotating equipment. In a typical application, the transducer mounts directly on bearing housings to detect early signs of imbalance, misalignment, or bearing wear, enabling proactive maintenance that reduces unplanned downtime.

Installation & Setup Guidance

Proper mounting is critical for accurate readings. The 190501-04-00-CN can be installed in any orientation, but the mounting surface must be clean and flat (33 mm diameter, 1.3 in). Apply the specified mounting torque of 4.5 N-m ± 0.6 N-m (40 in-lbf ± 5 in-lbf) to ensure consistent coupling. Use the provided Stud M6x1 with adapter for secure attachment. The maximum cable length is 305 meters (1,000 ft.) using cable part number 02173006 without signal degradation. Verify polarity: Pin A goes positive with respect to Pin B when velocity is from base to top.

Maintenance & Reliability

The 190501-04-00-CN requires minimal routine maintenance due to its sealed 316L stainless steel construction and internal electronics isolated from the case. Periodic inspection of the cable and connector for damage is recommended. The transducer withstands shock up to 5000 g pk and operates in 100% condensing humidity (non-submerged). Its magnetic field susceptibility is <0.0068 mm/s/gauss (0.268 mil/s/gauss) at 50 gauss, 50-60 Hz, ensuring reliable performance in electrically noisy environments.
