These specifications ensure accurate vibration measurement even in demanding conditions. The transducer's internal electronics are isolated from the case, reducing ground loop interference. Additionally, the mounting torque is specified at 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf) for secure installation.

Applications and Use Cases

The 190501-10-00-CN is ideal for monitoring rotating machinery such as pumps, motors, fans, and compressors. Its frequency response covers typical machine vibration frequencies, making it suitable for both low-speed and high-speed equipment. The transducer can be mounted in any orientation, offering flexibility in tight spaces. Moreover, its rugged construction withstands harsh industrial environments, including high humidity and magnetic fields.

Installation and Setup

Proper installation is crucial for accurate readings. The 190501-10-00-CN comes with a plate stud M6x1 to M6x1 mounting hardware option and a 3/8-24 adapter. The connection interface is MIL-C-5015, ensuring a secure and reliable electrical connection. For best results, mount the transducer on a flat, clean surface and apply the specified mounting torque. The polarity is defined: Pin A goes positive with respect to Pin B when velocity is from base to top of the transducer. Always follow the manufacturer's installation manual for detailed guidance.

Maintenance and Reliability

Routine inspection is essential to maintain the transducer's performance. Periodically check the mounting integrity and the condition of the cable. The unit is designed for long-term reliability, but environmental factors like extreme temperatures or vibration can affect performance. Regular calibration checks are recommended to ensure accuracy. By following a simple maintenance schedule, you can extend the service life of the 190501-10-00-CN and avoid unexpected downtime.

Compatibility and Integration

The 190501-10-00-CN is a standalone velocity transducer that outputs a voltage proportional to velocity. It can be integrated with most vibration monitoring systems that accept standard velocity transducer signals. The maximum cable length is 305 metres (1,000 ft.) with no signal degradation, allowing flexible placement of monitoring equipment.
