One standout spec is the broadband electrical noise of only 350 μg (3,434 μm/s²) from 1-10 kHz. This low noise floor allows the 200350-01-00-00 to detect subtle vibration changes that might otherwise be masked, improving early fault detection.

Applications and Use Cases for the 200350-01-00-00

In industrial settings, vibration monitoring is critical for predictive maintenance. The 200350-01-00-00 excels in applications such as pumps, motors, fans, compressors, and turbines. Its wide frequency range captures both low-speed and high-speed machinery vibrations. For example, in a chemical processing plant, this accelerometer can monitor pump bearings continuously, helping to prevent unplanned downtime. Additionally, its IP68 rating makes it suitable for food processing or marine environments where washdowns are routine.

Installation and Setup Guide

Mounting the 200350-01-00-00 correctly is essential for accurate readings. Use the 1/4-28 female thread and apply a mounting torque between 2 and 5 ft-lb (2.7 to 6.8 N-m). The accelerometer comes with a ¼-28 to M6 x 1.00 stainless steel stud for flexible attachment. Ensure the mounting surface is clean, flat, and free of debris to achieve optimal coupling. Connect the 2-pin Mil-C-5015 top connector to your monitoring system, and verify the excitation voltage is within 18 to 28 VDC with a constant current of 2 to 20 mA. Allow a settling time of 2.0 seconds (within 1% of bias) before taking measurements.

Maintenance and Reliability Tips

To maintain reliable performance, inspect the 200350-01-00-00 periodically for physical damage or corrosion on the connector and housing. Since it is hermetically sealed, no internal cleaning is required. Check the output bias voltage (8 to 12 VDC) during routine calibration to ensure the sensor remains within spec. The ceramic shear sensing element provides long-term stability, but verify the amplitude linearity (±1%) annually. For installations in high-humidity or condensing environments, the IP68 rating ensures the accelerometer remains protected.

Compatibility and Integration

The 200350-01-00-00 integrates seamlessly with Bently Nevada monitoring systems and most industrial data acquisition platforms that accept standard IEPE (ICP) sensors. Its output impedance of less than 150 ohms allows for long cable runs without signal degradation. The electrical isolation from case (>108 ohms) prevents ground loops in complex installations. For system integration, ensure your power supply provides 18-28 VDC and 2-20 mA constant current excitation.
