Applications and Use Cases

The 190501-11-00-00 is ideal for monitoring rotating equipment such as turbines, compressors, and electric motors. Its wide frequency response and high shock tolerance make it suitable for both steady-state and transient vibration analysis. For example, in a petrochemical plant, this transducer can detect early bearing wear, preventing unplanned downtime. Moreover, its rugged construction allows installation in harsh environments, including high-humidity areas.

Installation and Setup

Proper installation is critical for accurate measurements. The transducer mounts via a 1/4-28 stud (as per the mounting hardware option) and requires a mounting torque of 4.5 N-m ± 0.6 N-m. Ensure the mounting surface is clean and flat to achieve optimal frequency response. The MIL-C-5015 connector provides a secure, weatherproof connection, and the internal ground isolation simplifies wiring in systems with potential ground loops.

Maintenance and Reliability

Regular inspection of the transducer and its cabling is recommended to maintain reliable operation. Check for physical damage, loose connections, and signs of corrosion. The 316L stainless steel case resists rust, extending service life. Since the transducer has no moving parts, it requires minimal maintenance, reducing total cost of ownership. For long-term reliability, verify the output bias voltage periodically to ensure the internal electronics are functioning correctly.

Compatibility and Integration

The 190501-11-00-00 is compatible with Bently Nevada vibration monitoring systems that accept velocity transducer inputs. Its standard MIL-C-5015 connection interface allows easy integration with existing cabling. The transducer's low output impedance (<400 Ω) ensures signal integrity over long cable runs, up to 305 meters, making it suitable for large facilities.
