190501-11-00-00 | Bently Nevada Velomitor CT Velocity Transducer

Introduction to the 190501-11-00-00

When rotating machinery experiences unexpected vibration, unplanned downtime can escalate quickly. The 190501-11-00-00 from Bently Nevada provides a dependable solution for continuous velocity monitoring. This Velomitor CT velocity transducer is engineered to capture accurate vibration data in demanding industrial environments.

With a sensitivity of 3.94 mV/mm/s (±5%), the 190501-11-00-00 translates mechanical motion into a clear electrical signal. Its frequency response spans 3.0 Hz to 900 Hz (±1.0 dB), covering the critical range for most rotating equipment. This makes it a practical choice for predictive maintenance programs.

Key Features and Technical Specifications

The 190501-11-00-00 offers several features that support reliable operation. Below are the core specifications extracted from the official datasheet:

• Sensitivity: 3.94 mV/mm/s (100 mV/in/s) ±5%.
• Frequency Response: 3.0 Hz to 900 Hz (180 to 54,000 cpm) ±1.0 dB; 1.5 Hz to 1.0 kHz (90 to 60,000 cpm) ±3.0 dB.
• Output Bias Voltage: 10.1 Vdc ± 1.0 Vdc, Pin A referenced to Pin B.
• Dynamic Output Impedance: <400 Ω typical.

• Case Material: 316L stainless steel.
• Connector: 2-pin 316L stainless steel MIL-C5015, top.
• Mounting Torque: 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf).

These specifications ensure that the 190501-11-00-00 delivers consistent performance across a wide range of operating conditions. The internal electronics are isolated from the case, reducing the risk of ground loops.

Real-World Applications

The 190501-11-00-00 is suitable for vibration monitoring on pumps, fans, compressors, and other rotating machinery. Its robust design allows installation in harsh environments, including areas with high humidity or temperature extremes. For example, in a chemical plant, the transducer can be mounted on a motor to detect early signs of bearing wear, enabling maintenance teams to schedule repairs before failure occurs.

Because the transducer operates over a wide temperature range, it is also effective in outdoor installations or unheated facilities. The 316L stainless steel case provides corrosion resistance, making it ideal for offshore or coastal applications.

Installation and Setup

Proper mounting is essential for accurate readings. The 190501-11-00-00 includes a plate stud mounting option (3/8-in 24 to 1/4-in 28). Use the recommended mounting torque of 4.5 N-m ± 0.6 N-m to secure the transducer. The mounting surface should be flat and clean to ensure good contact.

For wiring, connect Pin A and Pin B according to the polarity note: Pin A goes positive with respect to Pin B when velocity is from base to top. The MIL-C-5015 connection interface simplifies installation and provides a secure, weather-resistant connection. Ensure the cable length does not exceed 305 metres to avoid signal degradation.

Maintenance and Reliability

Routine inspection of the transducer and its mounting is recommended to maintain reliable operation. Check for any signs of physical damage, loose mounting, or corrosion. The 190501-11-00-00 has no moving parts, which reduces wear and extends service life.

Given its robust construction and wide operating temperature range, the transducer requires minimal maintenance. Periodic verification of the output bias voltage (10.1 Vdc ± 1.0 Vdc) can help confirm proper function. Always follow the manufacturer's guidelines for any maintenance procedures.

Compatibility and Integration

The 190501-11-00-00 is designed to work with Bently Nevada monitoring systems and other vibration monitoring equipment that accepts standard velocity transducer inputs. The MIL-C-5015 connector is a common interface, making integration straightforward.
