Bently Nevada 190501-12-00-01 Velomitor CT Velocity Transducer Overview

Product Introduction

When machinery vibration threatens uptime, the Bently Nevada 190501-12-00-01 Velomitor CT velocity transducer provides accurate, reliable data for condition monitoring. This transducer is designed to convert mechanical velocity into an electrical signal, enabling early detection of bearing wear, imbalance, and misalignment. As part of the trusted Bently Nevada family, it delivers consistent performance in demanding industrial environments.

Technical Specifications Breakdown

The 190501-12-00-01 offers a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%, ensuring precise measurement of vibration velocity. 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. The output bias voltage is 10.1 Vdc ± 1.0 Vdc, referenced from Pin A to Pin B. 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 a shock limit of 5000 g pk maximum. The case is made of 316L stainless steel, with a 2-pin MIL-C-5015 connector. Weight is less than 297 g (10.5 oz).

Industry Applications

This velocity transducer is ideal for monitoring rotating equipment such as pumps, compressors, fans, and turbines. In a refinery, for example, the 190501-12-00-01 can be mounted on a centrifugal compressor to detect early-stage bearing faults. Its wide frequency response and robust construction make it suitable for continuous operation in hazardous areas, with agency approvals including CSA/NRTL/C (Class I, Division 1) and ATEX/IECEx/CSA (Class I, Zone 0/1).

Installation & Setup Guidance

Mount the transducer using the plate stud 3/8-in 24 to M8x1 hardware option. Apply a mounting torque of 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf). The device can be mounted at any angle. Connect via the MIL-C-5015 interface, ensuring Pin A goes positive with respect to Pin B when velocity is from base to top of the transducer. Maximum cable length is 305 metres (1,000 ft.) using part number 02173006 without signal degradation. For hazardous area installations, follow drawing 167536.

Maintenance & Reliability

From a maintenance engineer's perspective, the 190501-12-00-01 requires minimal routine care. Periodically inspect the cable and connector for damage. The internal electronics are isolated from the case, reducing ground loop issues. The 316L stainless steel case resists corrosion in harsh environments. Regular calibration checks ensure continued accuracy. For safety-rated installations, always follow the manufacturer's guidelines.

Selection Guide & Purchasing Advice

Before ordering, verify the agency approval option (01 for CSA/NRTL/C and ATEX/IECEx/CSA) matches your area classification. Confirm the mounting hardware and connection interface meet your installation requirements.
