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

Product Introduction

When unplanned machinery downtime threatens productivity, the Bently Nevada 190501-02-00-00 Velomitor CT Velocity Transducer provides reliable vibration monitoring. This sensor is designed for industrial environments where accurate velocity measurements are critical for predictive maintenance. Manufactured in the U.S.A., this transducer is part of the trusted Bently Nevada product line, known for precision and durability in rotating machinery protection.

Technical Specifications Breakdown

The 190501-02-00-00 offers a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%, ensuring consistent output for vibration analysis. Its frequency response spans 3.0 Hz to 900 Hz (180 to 54,000 cpm) ±1.0 dB, with an extended range of 1.5 Hz to 1.0 kHz (90 to 60,000 cpm) ±3.0 dB. This makes it suitable for monitoring low to medium-speed rotating equipment. The output bias voltage is 10.1 Vdc ± 1.0 Vdc, referenced from Pin A to Pin B, and the dynamic output impedance is less than 400 Ω typical. The transducer can handle cable lengths up to 305 metres (1,000 ft.) using part number 02173006 without signal degradation.

Industry Applications

This velocity transducer excels in monitoring fans, pumps, compressors, and turbines where early detection of imbalance or bearing wear is essential. In petrochemical plants, the 190501-02-00-00 helps reduce unplanned shutdowns by providing real-time vibration data. Its robust design also suits power generation facilities, where continuous operation demands reliable sensor performance. Compared to similar sensors, its wide frequency range and stable sensitivity offer consistent data for trend analysis.

Installation & Setup Guidance

Mount the transducer using the included stud option (3/8-in 24 to 1/2-in 20) with a torque of 4.5 N-m ± 0.6 N-m (40 in-lbf ± 5 in-lbf). The mounting surface should be 33 mm diameter (1.3 in diameter), and the transducer height is 82 mm (3.2 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, offering flexibility in tight spaces. Use the MIL-C-5015 connection interface for secure wiring.

Maintenance & Reliability

The 190501-02-00-00 is built with a 316L stainless steel case and connector, providing corrosion resistance in harsh environments. Its operating temperature range is -40°C to +85°C (-40°F to +185°F), and it can withstand shock limits of 5000 g pk maximum. For long-term reliability, inspect the cable and connector periodically for wear. The internal electronics are isolated from the case, reducing ground loop issues. Routine calibration checks ensure measurement accuracy over time.

Selection Guide & Purchasing Advice

When selecting the 190501-02-00-00, verify your mounting hardware requirements and cable length needs. This model comes with no agency approvals (option 00), so confirm if your application requires intrinsic safety certifications.
