190501-02-00-01 | Bently Nevada Velomitor CT Velocity Transducer

Why Choose the 190501-02-00-01 Velomitor CT?

When rotating machinery faces unpredictable vibration, the 190501-02-00-01 from Bently Nevada provides precise velocity measurement. This Velomitor CT transducer is engineered for industrial environments where accuracy and durability matter. With a sensitivity of 3.94 mV/mm/s (±5%), it captures vibration data consistently.

The transducer operates across a frequency response of 3.0 Hz to 900 Hz (±1.0 dB) and 1.5 Hz to 1.0 kHz (±3.0 dB). This range covers typical machine vibration signatures. Its amplitude linearity of ±2% to 63.5 mm/s pk ensures reliable readings.

Built with 316L stainless steel, the 190501-02-00-01 withstands harsh conditions. It operates from -40°C to +85°C and stores from -40°C to +100°C. The unit weighs only 0.297 kg, simplifying installation.

Key Features and Technical Specifications

These specifications ensure the 190501-02-00-01 delivers accurate vibration data. Its internal electronics are isolated from the case, reducing ground loop issues. The transducer's transverse response is less than 5% of axial sensitivity, minimizing cross-axis errors.

Applications and Use Cases

In industrial plants, the 190501-02-00-01 monitors pumps, motors, and fans. It suits machinery where velocity measurements indicate mechanical health. The transducer's robust design handles demanding environments, including those with high humidity or magnetic fields.

For example, in a paper mill, the transducer tracks roll vibrations, helping avoid unplanned downtime. Its magnetic field susceptibility of <0.0068 mm/s/gauss at 50 gauss ensures stable readings near motors. The mounting angle can be any orientation, offering flexible installation.

Installation and Setup

Mount the 190501-02-00-01 using the stud 3/8-in 24 to 1/2-in 20 option. Apply a mounting torque of 4.5 N-m ± 0.6 N-m (40 in-lbf ± 5 in-lbf). The connector is a 2-pin 316L stainless steel MIL-C-5015, top-mounted. Ensure the mounting surface is 33 mm diameter (1.3 in) for proper seating.

For wiring, connect Pin A and Pin B as per the output bias voltage. The polarity is such that Pin A goes positive with respect to Pin B when velocity is from base to top. Use the specified cable (part number 02173006) for optimal signal integrity.

Maintenance and Reliability

Regular inspection of the transducer and its cable is recommended. Check for physical damage or corrosion, especially in harsh environments. The 316L stainless steel case resists corrosion, but periodic checks ensure long-term reliability.

The transducer's temperature sensitivity varies from -8% to +5% over the operating range. This is typical for velocity transducers. By monitoring output bias voltage, you can detect early signs of degradation. If readings drift, verify the mounting torque and cable condition.

Compatibility and Integration

The 190501-02-00-01 connects to Bently Nevada monitoring systems. Its MIL-C-5015 interface ensures compatibility with standard connectors. The transducer's output is a voltage signal, making it easy to integrate with data acquisition systems.

For hazardous areas, the transducer carries agency approvals: CSA/NRTL/C (Class I, Division 1) and ATEX/IECEx/CSA (Class I, Zone 0/1). These certifications allow use in explosive atmospheres, following installation drawing 167536.
