The IP68 rating is a key advantage. It ensures protection against dust and prolonged immersion. This makes the 200350-11-00-00 ideal for wet or dirty environments.

Applications and Use Cases

This accelerometer suits rotating machinery monitoring. It works well in pumps, fans, and compressors. The wide frequency range captures both low-speed and high-speed vibrations. In addition, the ceramic shear sensing element provides stable measurements over time. Consequently, maintenance teams can detect early bearing wear or imbalance.

Installation and Setup

Mount the 200350-11-00-00 using the M6x1 adhesive stud mount. Apply a mounting torque between 2 and 5 ft-lb (2.7 to 6.8 N-m). Ensure the mounting surface is clean and flat. Then connect the 2-pin Mil-C-5015 connector. Finally, verify the output bias voltage is between 8 and 12 VDC before operation.

Maintenance and Reliability

Regular inspection of the cable and connector is recommended. Check for signs of wear or corrosion. The welded hermetic seal prevents moisture ingress. As a result, the unit maintains performance in condensing humidity. For long-term reliability, follow the manufacturer's guidelines.
