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

Introduction to the Bently Nevada 190501-00-00-00

When machinery vibration threatens uptime, the 190501-00-00-00 from Bently Nevada provides the precise measurement you need. This Velomitor CT velocity transducer is engineered for industrial environments where accuracy and durability are non-negotiable. With a sensitivity of 3.94 mV/mm/s (±5%), it captures vibration data with exceptional clarity, enabling early detection of mechanical faults.

Built in the U.S.A., this transducer features a 316L stainless steel case and connector, ensuring long-term resistance to corrosion and harsh conditions. Its compact design—82 mm in height and 33 mm mounting surface diameter—allows for easy integration into existing monitoring systems. The 190501-00-00-00 is a cost-effective solution for predictive maintenance programs, reducing unplanned downtime and extending equipment life.

One distinctive feature is the base strain sensitivity of 0.43 mm/s/μstrain, which minimizes false readings from mounting surface strain. This translates to more accurate data and fewer false alarms, saving you time and money on unnecessary inspections.

Applications and Use Cases

The 190501-00-00-00 is ideal for monitoring rotating machinery such as pumps, motors, fans, and compressors. Its robust design makes it suitable for harsh environments, including those with high humidity (100% condensing, non-submerged) and magnetic fields (susceptibility <0.0068 mm/s/gauss @ 50 gauss, 50-60Hz).

For example, in a petrochemical plant, this transducer can be mounted on a critical pump to detect bearing wear early. By catching issues before they escalate, you avoid costly production stoppages and extend the pump's service life—a direct boost to your bottom line.

Installation and Setup

Mounting the 190501-00-00-00 is straightforward. The transducer can be oriented at any angle, and the recommended mounting torque is 4.5 N-m ± 0.6 N-m (40 in-lbf ± 5 in-lbf). The connection interface is a MIL-C-5015 2-pin connector, ensuring a secure and reliable electrical connection.

For optimal performance, ensure the mounting surface is clean and flat. The transducer's internal electronics are isolated from the case, which helps prevent ground loops. Maximum cable length is 305 meters (1,000 ft.) using cable part number 02173006, with no signal degradation—allowing flexible placement of monitoring equipment.

Maintenance and Reliability

Regular inspection of the transducer and its mounting is recommended to ensure accurate readings. Check for any signs of physical damage or corrosion, especially in harsh environments. The 316L stainless steel construction offers excellent resistance to corrosion, but periodic verification of the output bias voltage (10.1 Vdc ± 1.0 Vdc) can confirm proper operation.

By incorporating the 190501-00-00-00 into your predictive maintenance routine, you reduce the risk of unexpected failures. The transducer's high shock limit (5000 g pk) and wide operating temperature range make it a reliable choice even in demanding conditions, minimizing replacement costs over time.

Compatibility and Integration

The 190501-00-00-00 is designed to work with Bently Nevada monitoring systems. Its standard velocity output (3.94 mV/mm/s) is compatible with most vibration monitoring equipment. The MIL-C-5015 connection interface ensures easy integration with existing cabling.

For new installations, the transducer can be paired with a compatible monitor to provide continuous vibration data. This integration enables trend analysis, helping you identify developing faults before they cause downtime—a key factor in reducing maintenance costs.
