Applications and Use Cases

The 9200-01-20-10-00Its two-wire configuration simplifies wiring and reduces installation costs. The transducer's 4.5 Hz minimum operating frequency makes it suitable for low-speed machinery. Additionally, its dust and moisture resistance ensures reliable operation in harsh industrial settings.

Installation and Setup

Mount the transducer using the circular M10X1 stud base. Orient it at the angle of calibration to maintain the ±5% sensitivity tolerance. Connect the 20-foot cable to terminals A and B with a 10 kΩ load for proper calibration. Ensure the mounting surface is clean and rigid to avoid measurement errors.

Maintenance and Reliability

Regularly inspect the transducer for physical damage and ensure the cable is not stressed or pinched. Because the unit is dust and moisture resistant, it requires minimal maintenance. Periodically verify the output signal against a known reference to confirm calibration integrity.

Compatibility and Integration

The 9200-01-20-10-00 works with Bently Nevada monitoring systems and any data acquisition system that accepts a 20 mV/mm/s velocity input. Its two-wire design is compatible with standard loop-powered transmitters.

Troubleshooting and Common Issues

If the output signal is absent, check the wiring to terminals A and B. Ensure the load is 10 kΩ; an incorrect load can affect sensitivity. If readings drift, verify the transducer is oriented at the calibration angle. For persistent issues, consult the Bently Nevada manual.
