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

Product Introduction

When machine vibration threatens uptime, the Bently Nevada 190501-01-00-00 Velomitor CT Velocity Transducer delivers precise, reliable measurements. This transducer converts velocity into a proportional electrical signal, enabling early detection of rotating machinery faults. Manufactured in the U.S.A., it is designed for continuous monitoring in harsh industrial environments.

Technical Specifications Breakdown

The 190501-01-00-00 offers a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%, ensuring accurate vibration amplitude readings. Its frequency response covers 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. The output bias voltage is 10.1 Vdc ± 1.0 Vdc, and the dynamic output impedance is less than 400 Ω typical. The transducer operates from -40°C to +85°C and stores from -40°C to +100°C. It withstands shock up to 5000 g pk and operates in 100% condensing humidity. The case is 316L stainless steel, with a height of 82 mm (3.2 in) and a weight of 0.297 kg. It uses a MIL-C-5015 connection interface and a 3/8-in 24 stud mount.

Industry Applications

Maintenance engineers rely on this transducer for critical assets like steam turbines, centrifugal compressors, and large fans. Its wide frequency response captures both low-speed and high-speed vibration components. The robust stainless steel construction withstands corrosive atmospheres in chemical plants and refineries. The internal electronics are isolated from the case, reducing ground loop issues and simplifying installation.

Installation & Setup Guidance

Mount the transducer using the 3/8-in 24 stud with a torque of 4.5 N-m ± 0.6 N-m (40 in-lbf ± 5 in-lbf). The mounting surface must be flat and clean, with a 33 mm diameter. Orientation can be any angle, making it flexible for tight spaces. Connect via the MIL-C-5015 2-pin connector, observing polarity: Pin A goes positive with respect to Pin B when velocity is from base to top. Maximum cable length is 305 metres (1,000 ft.) with part number 02173006 cable, with no signal degradation.

Maintenance & Reliability

For maintenance engineers, the 190501-01-00-00 requires minimal routine care. Periodically inspect the cable and connector for damage. Verify the mounting torque remains within specification. The sealed 316L stainless steel case protects against moisture and contaminants. The transducer's temperature sensitivity varies -8% to +5% over the operating range, so account for this in system calibration. With no moving parts, this design offers long service life and consistent performance.

Selection Guide & Purchasing Advice

Before ordering, confirm your system's compatibility with the 190501-01-00-00's output characteristics. This model has no agency approvals, so verify if your application requires intrinsic safety certifications (available in other options).
