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

Product Introduction

When machinery vibration threatens uptime, the Bently Nevada 190501-04-00-04 Velomitor CT Velocity Transducer delivers precise measurements. This transducer is built for continuous monitoring in demanding industrial settings, providing engineers with accurate velocity data to detect early signs of imbalance, misalignment, or bearing wear. As a maintenance engineer, you need reliability and ease of service—this model delivers both with its robust design and straightforward installation.

Technical Specifications Breakdown

The 190501-04-00-04 offers a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%, ensuring consistent signal output across its operating range. 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—ideal for capturing low-speed to moderate-speed machinery vibrations. The output bias voltage is 10.1 Vdc ± 1.0 Vdc (Pin A referenced to Pin B), and the dynamic output impedance is less than 400 Ω typical. With a mounted resonant frequency of 9 kHz minimum (stud mounted, except quick disconnect), this transducer resents false readings from structural resonances.

Industry Applications

This transducer excels in rotating equipment monitoring, such as pumps, fans, compressors, and turbines. For example, in a petrochemical plant, the 190501-04-00-04 can be mounted on a centrifugal compressor to detect velocity changes that indicate blade fouling or bearing degradation. Its intrinsic safety approvals (Ex ia IIC T4, AEx ia IIC T4) make it suitable for Class I, Division 1, Groups A, B, C, D environments, ensuring safe operation in hazardous areas. Maintenance engineers appreciate its ability to provide early warnings, reducing unplanned downtime and extending equipment life.

Installation & Setup Guidance

Mounting the 190501-04-00-04 is straightforward. Use the provided stud M6x1 with 3/8-in 24 adapter (mounting hardware option 04) and tighten to a torque of 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf). The transducer can be oriented at any angle, simplifying placement in tight spaces. Connect via the MIL-C-5015 interface (connection option 00) using cable part number 02173006, which supports lengths up to 305 metres (1,000 ft.) without signal degradation. Ensure the mounting surface is clean and flat (33 mm diameter) for optimal coupling.

Maintenance & Reliability

Routine inspection of the transducer and cable is recommended to maintain signal integrity. The 316L stainless steel case and connector resist corrosion in harsh environments. Operating temperature range is -40°C to +85°C (-40°F to +185°F), with storage up to +100°C (+212°F). The unit withstands 5000 g pk shock and 100% condensing humidity (non-submerged). With a weight of less than 297 g (10.5 oz.), it is easy to handle during replacement. For complete technical specifications, contact BluePLC Industrial.

Buying Guide & Selection Advice
