Product Overview
When machinery vibration threatens uptime, the Bently Nevada 190501-14-00-CN Velomitor CT Velocity Transducer delivers precise measurements to protect your assets. This velocity transducer converts mechanical vibration into an electrical signal proportional to velocity, enabling early detection of bearing wear, imbalance, and misalignment. Designed for continuous operation in harsh environments, it provides maintenance engineers with reliable data for condition-based monitoring.
Technical Specifications
The 190501-14-00-CN offers a sensitivity of 3.94 mV/mm/s (100 mV/in/s) ±5%, ensuring accurate vibration readings. 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 sits at 10.1 Vdc ± 1.0 Vdc, referenced from Pin A to Pin B. Dynamic output impedance remains below 400 Ω typical, and the broadband noise floor is 0.229 mm/s (0.009 in/s) pk. Amplitude linearity holds within ±2% up to 63.5 mm/s pk (2.5 in/s pk). The mounted resonant frequency exceeds 9 kHz minimum when stud mounted (except quick disconnect). Internal electronics are isolated from the case, and the maximum cable length reaches 305 metres (1,000 ft.) using part number 02173006 without signal degradation.
Industry Applications
In rotating machinery such as pumps, fans, compressors, and turbines, the 190501-14-00-CN provides continuous velocity monitoring. Its wide frequency response captures both low-speed and high-speed vibration components, making it suitable for variable-speed drives. For example, in a petrochemical plant, this transducer can detect early-stage bearing faults before they cause catastrophic failure, reducing unplanned downtime and maintenance costs. The transducer's robust 316L stainless steel case withstands corrosive environments, ensuring long service life.
Installation & Setup Guidance
Mount the 190501-14-00-CN using the provided 3/8-in 24 to 1/4-in 20 adapter. Apply a mounting torque of 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf) to ensure proper mechanical coupling. The transducer can be mounted at any angle, but ensure the mounting surface is clean and flat (33 mm diameter, 1.3 in). Use the 2-pin 316L stainless steel MIL-C-5015 connector for electrical connection. Polarity is critical: Pin A goes positive with respect to Pin B when velocity is from base to top of the transducer. Route cables away from high-voltage sources and maintain a maximum cable length of 305 metres to avoid signal degradation.
Maintenance & Reliability
Routine inspection of the transducer and its cable connections helps maintain measurement accuracy. Check for physical damage, corrosion, or loose mounting. The transducer operates reliably from -40°C to +85°C (-40°F to +185°F) and can be stored from -40°C to +100°C (-40°F to +212°F). Its 316L stainless steel case resists corrosion, and the internal electronics are isolated from the case, reducing ground loop issues. With a shock limit of 5000 g pk maximum, the transducer withstands harsh industrial conditions. Humidity up to 100% condensing (non-submerged) is acceptable. Magnetic field susceptibility is less than 0.0068 mm/s/gauss (0.268 mil/s/gauss) at 50 gauss, 50-60 Hz.
Compatibility & Integration
The 190501-14-00-CN integrates with Bently Nevada monitoring systems and other vibration data acquisition equipment. Its standard MIL-C-5015 connection interface simplifies wiring. The transducer's sensitivity of 3.94 mV/mm/s matches typical input ranges of vibration monitors. Ensure the monitoring system supports the output bias voltage of 10.1 Vdc and can handle the dynamic output impedance below 400 Ω. For extended cable runs, use the specified cable part number 02173006 to maintain signal integrity.
Selection Guide & Purchasing Advice
Before purchasing the 190501-14-00-CN, verify the mounting hardware option (1: 4 Adapter, 3/8-in 24 to 1/4-in 20) and connection option (0: MIL-C-5015). The agency approval option (CN Country Specific) ensures compliance with local regulations. Confirm that the transducer's frequency range and sensitivity meet your application requirements. SpareTechPLC stocks this model and can advise on compatibility with your existing monitoring system. Please verify current lifecycle status and availability with SpareTechPLC before ordering.
