Bently Nevada 190501-14-00-CN Velomitor CT Velocity Transducer Overview

Product Introduction

When unplanned downtime threatens production targets, the Bently Nevada 190501-14-00-CN Velomitor CT Velocity Transducer delivers reliable vibration monitoring. This sensor converts mechanical velocity into a proportional electrical signal, enabling early detection of rotating machinery faults. Designed for harsh environments, it offers a cost-effective solution for predictive maintenance programs.

Technical Specifications Breakdown

The 190501-14-00-CN provides a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%, ensuring accurate vibration measurement. 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 wide bandwidth captures both low-speed and high-speed machinery vibrations, reducing the risk of missed fault signatures. The output bias voltage of 10.1 Vdc ± 1.0 Vdc simplifies integration with monitoring systems, lowering installation costs. With a mounted resonant frequency of 9 kHz minimum, the transducer avoids resonance interference in most industrial applications, enhancing measurement reliability.

Industry Applications

In the oil and gas sector, the Bently Nevada 190501-14-00-CN monitors centrifugal pumps and compressors, detecting imbalance or bearing wear early to prevent catastrophic failures. For power generation, it tracks turbine vibrations, extending maintenance intervals and reducing lifecycle costs. Its 316L stainless steel case and 100% condensing humidity tolerance make it suitable for offshore and chemical processing environments where corrosion resistance is critical.

Installation & Setup Guidance

Mount the transducer using the included 3/8-in 24 to 1/4-in 20 adapter. Apply a mounting torque of 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf) to ensure proper coupling. The MIL-C-5015 connection interface simplifies wiring. 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. For optimal signal integrity, limit cable length to 305 metres (1,000 ft.) using cable part number 02173006.

Maintenance & Reliability

Routine inspection of the mounting surface and connector integrity ensures consistent performance. The internal electronics are isolated from the case, reducing ground loop issues and maintenance costs. With an operating temperature range of -40°C to +85°C (-40°F to +185°F), the 190501-14-00-CN withstands extreme conditions, minimizing sensor replacement frequency. Its shock limit of 5000 g pk maximum protects against accidental impacts during service.
