Bently Nevada 190501-01-00-00 Velomitor CT Velocity Transducer

Product Introduction

When machinery vibration threatens uptime and safety, the Bently Nevada 190501-01-00-00 Velomitor CT Velocity Transducer delivers precise, reliable measurements. This industrial-grade sensor is designed for continuous monitoring of rotating equipment such as turbines, compressors, and pumps. Manufactured in the U.S.A., it provides accurate velocity output to help detect early signs of bearing wear, imbalance, or misalignment.

Technical Specifications

The 190501-01-00-00 offers a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%, ensuring consistent signal output. 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, covering a broad range of vibration frequencies. 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. Amplitude linearity holds within ±2% up to 63.5 mm/s pk (2.5 in/s pk). The mounted resonant frequency is 9 kHz minimum (stud mounted, except quick disconnect). Broadband base strain sensitivity is 0.43 mm/s/μstrain (0.017 in/s/μstrain). The internal electronics are isolated from the case, and maximum cable length reaches 305 metres (1,000 ft.) with part number 02173006 without signal degradation.

Industry Applications

This velocity transducer excels in oil and gas, power generation, and heavy manufacturing environments. For example, on a steam turbine, the 190501-01-00-00 mounts directly to bearing housings to monitor shaft vibration. Its wide operating temperature range of -40°C to +85°C (-40°F to +185°F) and 100% condensing humidity tolerance make it suitable for outdoor and washdown areas. The shock limit of 5000 g pk ensures survival in high-impact machinery.

Installation & Setup Guidance

Mount the transducer using the included 3/8-in-24 stud with a torque of 4.5 N-m ± 0.6 N-m (40 in-lbf ± 5 in-lbf). The MIL-C-5015 connection interface provides a secure, weatherproof electrical connection. The transducer can be oriented at any angle, and polarity is defined: Pin A goes positive with respect to Pin B when velocity is from base to top. Ensure the mounting surface is clean and flat (33 mm diameter minimum) for accurate readings.

Maintenance & Reliability

Routine inspection of the cable and connector integrity helps maintain signal quality. The 316L stainless steel case resists corrosion in harsh chemical or marine environments. No internal adjustments are required; the transducer is factory-calibrated. For long-term reliability, verify mounting torque periodically and replace the unit if output bias voltage drifts outside the specified range.

Selection Guide & Purchasing Advice

Before ordering, confirm that your application requires a velocity transducer with a stud mount and MIL-C-5015 connector. This model (agency approval option 00) has no intrinsic safety approvals, so for hazardous areas, select a variant with approvals (options 01-04).
