Bently Nevada 190501-12-00-04 Velomitor CT Velocity Transducer Overview

Product Introduction

When unplanned downtime from machinery vibration threatens production targets, the Bently Nevada 190501-12-00-04 Velomitor CT Velocity Transducer provides reliable, real-time velocity measurements. Designed for harsh industrial environments, this transducer converts mechanical motion into an electrical signal for predictive maintenance and protection systems. Manufactured in the U.S.A., the 190501-12-00-04 is part of the trusted Velomitor CT series, known for accuracy and durability in rotating machinery monitoring.

Technical Specifications Breakdown

The 190501-12-00-04 delivers a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%, ensuring precise velocity detection. 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, covering critical vibration frequencies. The transducer operates reliably across -40°C to +85°C (-40°F to +185°F) and withstands shock up to 5000 g pk. Output bias voltage is 10.1 Vdc ± 1.0 Vdc, with dynamic output impedance less than 400 Ω typical. These parameters make it suitable for continuous monitoring in demanding applications.

Industry Applications

In the oil and gas sector, the 190501-12-00-04 monitors pumps and compressors for early signs of bearing wear or imbalance. For power generation, it tracks turbine vibrations to prevent catastrophic failures. Its ATEX/IECEx/CSA (Class I, Zone 0/1) and CSA/NRTL/C (Class I, Division 1) approvals allow safe use in hazardous areas. Compared to similar velocity transducers, the 190501-12-00-04 offers superior transverse response (less than 5% of axial sensitivity) and amplitude linearity (±2% to 63.5 mm/s pk), ensuring accurate data even in complex vibration environments.

Installation & Setup Guidance

Mount the 190501-12-00-04 using the included plate stud 3/8-in 24 to M8x1 hardware. Apply a mounting torque of 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf) for secure attachment. The transducer can be oriented in any angle, and its 2-pin 316L stainless steel MIL-C-5015 connector simplifies wiring. Ensure the mounting surface is clean and flat (33 mm diameter) to maintain accuracy. For optimal signal integrity, use cable part number 02173006 up to 305 metres (1,000 ft.) without degradation.

Maintenance & Reliability

Routine inspection of the transducer and cable connections helps maintain performance. The 316L stainless steel case resists corrosion in humid or chemically aggressive environments. With a humidity limit of 100% condensing (non-submerged) and magnetic field susceptibility below 0.0068 mm/s/gauss (0.268 mil/s/gauss) @ 50 gauss, 50-60 Hz, the 190501-12-00-04 delivers long-term reliability. Periodic verification of output bias voltage and frequency response ensures continued accuracy.

Selection Guide & Purchasing Advice

Before ordering the 190501-12-00-04, verify that your system requires a velocity transducer with sensitivity of 3.94 mV/mm/s and the specified frequency range. Confirm that the mounting hardware option (plate stud 3/8-in 24 to M8x1) matches your installation. For hazardous area compliance, note the Agency Approval Option 04 includes CSA/NRTL/C (Class I, Division 1) and ATEX/IECEx/CSA (Class I, Zone 0/1) certifications.
