Bently Nevada 190501-13-00-CN Velomitor CT Velocity Transducer Overview

Product Introduction

When machinery vibration threatens uptime and safety, the Bently Nevada 190501-13-00-CN provides a trusted solution. This Velomitor CT Velocity Transducer delivers accurate velocity measurements for rotating equipment, helping engineers detect early signs of imbalance, misalignment, or bearing wear. As part of Bently Nevada's renowned sensor family, it combines rugged construction with precise signal output.

Technical Specifications Breakdown

The 190501-13-00-CN features a sensitivity of 3.94 mV/mm/s (100 mV/in/s) with ±5% tolerance, ensuring consistent performance across monitoring points. Its frequency response spans 3.0 Hz to 900 Hz (180 to 54,000 cpm) at ±1.0 dB, and extends from 1.5 Hz to 1.0 kHz (90 to 60,000 cpm) at ±3.0 dB, covering a wide range of vibration frequencies common in industrial machinery. The transducer operates reliably from -40°C to +85°C, with storage capability from -40°C to +100°C, making it suitable for harsh environments. Output bias voltage is 10.1 Vdc ± 1.0 Vdc, referenced from Pin A to Pin B, providing a stable baseline for data acquisition systems.

Industry Applications

This velocity transducer excels in monitoring critical rotating assets such as turbines, compressors, pumps, and fans. In power generation, it helps detect rotor vibration changes that could lead to costly unplanned outages. In oil and gas facilities, its 316L stainless steel case and MIL-C-5015 connector withstand corrosive atmospheres while delivering reliable data. The transducer's ability to handle 100% condensing humidity and 5000 g pk shock limits makes it ideal for heavy industrial settings where conditions are demanding.

Installation & Setup Guidance

Mount the 190501-13-00-CN using the quick disconnect stud option (Mounting Hardware Option 1 3) with a torque of 4.5 N-m ± 0.6 N-m (40 in-lbf ± 5 in-lbf). The transducer can be installed at any orientation, offering flexibility in tight spaces. Ensure the mounting surface is clean and flat (33 mm diameter minimum) for optimal coupling. Cable runs up to 305 metres (1,000 ft.) using part number 02173006 cable are supported without signal degradation. Polarity is critical: Pin A goes positive with respect to Pin B when velocity is from base to top of the transducer.

Maintenance & Reliability

Routine inspection of the transducer and cable connections helps maintain measurement accuracy. The internal electronics are isolated from the case, reducing ground loop issues. With a mounted resonant frequency above 9 kHz (stud mounted, except quick disconnect), the sensor avoids resonance interference in most applications. Its temperature sensitivity variation of -8% to +5% typical over the operating range ensures stable output across temperature swings. For long-term reliability, verify the mounting torque periodically and inspect the connector for corrosion.

Selection Guide & Purchasing Advice

When selecting the 190501-13-00-CN, confirm the Agency Approval Option CN matches your regional requirements. The transducer's sensitivity and frequency response suit most vibration monitoring needs, but verify compatibility with your data acquisition system's input range.
