Product Overview
When vibration monitoring equipment fails unexpectedly, production downtime and costly repairs follow. The Bently Nevada 190501-00-00-00 Velomitor CT Velocity Transducer delivers consistent, accurate measurements to keep your machinery running smoothly. Designed for industrial environments, this transducer provides reliable velocity data for predictive maintenance programs.
Technical Specifications Breakdown
The 190501-00-00-00 offers a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%, ensuring precise vibration 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. 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, supporting signal integrity over long cable runs up to 305 metres (1,000 ft.) without degradation.
Industry Applications
In rotating machinery such as turbines, compressors, and pumps, the 190501-00-00-00 monitors vibration velocity to detect imbalance, misalignment, or bearing wear. Its wide operating temperature range of -40°C to +85°C (-40°F to +185°F) suits harsh environments like oil refineries and power plants. The 100% condensing humidity tolerance and 5000 g pk shock limit ensure reliable operation in demanding conditions.
Installation & Setup Guidance
Mount the transducer on a clean, flat surface with a diameter of 33 mm (1.3 in). Apply a mounting torque of 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf). The case material is 316L stainless steel, and the connector is a 2-pin 316L stainless steel MIL-C-5015 top-mounted type. Polarity is defined: Pin A goes positive with respect to Pin B when velocity is from base to top. Any mounting orientation is acceptable, simplifying installation in tight spaces.
Maintenance & Reliability
From a maintenance engineer's perspective, the 190501-00-00-00 requires minimal upkeep due to its robust construction. The internal electronics are isolated from the case, reducing ground loop issues. The transducer's mounted resonant frequency is 9 kHz minimum (stud mounted, except quick disconnect), ensuring stable readings. Regular inspection of the cable and connector for damage helps maintain signal quality. The unit's weight is less than 297 g (10.5 oz.), making it easy to handle during replacement.
Compatibility & Integration
This transducer integrates with Bently Nevada monitoring systems and other vibration analysis equipment. The maximum cable length of 305 metres (1,000 ft.) using part number 02173006 allows flexible placement of monitoring hardware. The output bias voltage and dynamic impedance are designed for compatibility with standard data collectors and condition monitoring systems.
Selection Guide & Purchasing Advice
Before purchasing the 190501-00-00-00, verify your mounting requirements and agency approval needs. This model comes with no mounting stud, a MIL-C-5015 connection interface, and no agency approvals. For intrinsically safe or non-incendive applications, consider options with approvals 01 through 04. SpareTechPLC stocks this transducer and can advise on compatible accessories. Please verify current lifecycle status and availability with SpareTechPLC before ordering.
