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 reliable, high-fidelity measurements. This velocity transducer is engineered for continuous monitoring in harsh industrial environments, providing critical data for predictive maintenance and asset protection.

Technical Specifications Breakdown

The 190501-04-00-04 offers a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%, ensuring precise vibration 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 low to medium frequency machinery vibrations. The output bias voltage is 10.1 Vdc ± 1.0 Vdc, referenced from Pin A to Pin B, while 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), and the mounted resonant frequency is 9 kHz minimum (stud mounted, except quick disconnect).

Industry Applications

The 316L stainless steel case resists corrosion, while the internal electronics are isolated from the case to prevent ground loops.

Installation & Setup Guidance

Mount the 190501-04-00-04 using the provided 4 stud M6x1 with 3/8-in 24 adapter. Apply a mounting torque of 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf) to ensure proper coupling. The transducer can be installed at any orientation, with polarity defined as Pin A going positive relative to Pin B when velocity is from base to top. For optimal signal integrity, use cable part number 02173006 up to 305 metres (1,000 ft.) without degradation.

Maintenance & Reliability

With a shock limit of 5000 g pk maximum and magnetic field susceptibility below 0.0068 mm/s/gauss (0.268 mil/s/gauss) at 50 gauss, 50-60 Hz, this transducer withstands demanding conditions. The base strain sensitivity is 0.43 mm/s/μstrain (0.017 in/s/μstrain), and broadband noise is only 0.229 mm/s (0.009 in/s) pk. Regular inspection of the mounting surface and connector integrity helps maintain long-term accuracy.

Selection Guide & Purchasing Advice

Before ordering, verify that the agency approval option 04 (CSA/NRTL/C Class I, Division 1; ATEX/IECEx/CSA Class I, Zone 0/1) matches your hazardous area requirements. The 190501-04-00-04 uses a MIL-C-5015 connection interface. For current availability and lifecycle status, contact AutoDCSTech, your trusted source for Bently Nevada components.
