Bently Nevada 190501-19-00-CN Velomitor CT Velocity Transducer Overview

Product Introduction

When machinery vibration threatens uptime and safety, the Bently Nevada 190501-19-00-CN Velomitor CT velocity transducer delivers precise, reliable measurements. Manufactured by Bently Nevada in the U.S.A., this transducer is designed for continuous monitoring of rotating and reciprocating equipment. Its 316L stainless steel case and MIL-C-5015 connector ensure durability in demanding industrial environments.

Technical Specifications

The 190501-19-00-CN offers a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%, providing accurate velocity readings. Its frequency response spans 3.0 Hz to 900 Hz (180 to 54,000 cpm) ±1.0 dB and extends to 1.5 Hz to 1.0 kHz (90 to 60,000 cpm) ±3.0 dB. The transducer operates from -40°C to +85°C (-40°F to +185°F) and stores from -40°C to +100°C (-40°F to +212°F). It withstands shock up to 5000 g pk and 100% condensing humidity. The output bias voltage is 10.1 Vdc ± 1.0 Vdc, with dynamic output impedance less than 400 Ω typical. Maximum cable length is 305 metres (1,000 ft.) using part number 02173006 without signal degradation. Weight is 0.297 kg (10.5 oz.), and height is 82 mm (3.2 in). Mounting torque is 4.5 N-m ± 0.6 N-m (40 in-lbf ± 5 in-lbf).

Industry Applications

This velocity transducer excels in monitoring critical assets such as turbines, compressors, pumps, and fans. In petrochemical plants, it provides early warning of bearing wear and imbalance. For power generation, it tracks vibration trends to schedule maintenance before unplanned outages. Its wide frequency range suits both slow-speed and high-speed machinery, making it versatile across industries.

Installation & Setup Guidance

Mount the 190501-19-00-CN in any orientation using the provided adapter (3/8-in 24 to 1/4-in 18 NPT). Apply 4.5 N-m ± 0.6 N-m torque for secure attachment. Ensure the mounting surface is clean and flat (33 mm diameter). Connect via the 2-pin MIL-C-5015 top connector, noting that Pin A goes positive with respect to Pin B when velocity is from base to top. Run cable up to 305 metres without signal loss. Grounding is isolated from the case, so follow standard practices for shielded cables.

Maintenance & Reliability

Routine inspection of the transducer and cable for physical damage ensures long service life. The 316L stainless steel case resists corrosion in harsh environments. Verify output bias voltage periodically to confirm electronics health. With no moving parts, the Velomitor CT design minimizes wear, reducing total cost of ownership. For critical applications, schedule calibration checks per manufacturer guidelines.

Selection Guide & Purchasing Advice
