Real-World Applications for the 200355-09-00-00

Industries rely on the 200355-09-00-00 for continuous vibration monitoring of pumps, fans, compressors, motors, and turbines. Its wide frequency range captures both slow-speed and high-speed machinery faults, while the IP68 rating allows installation in washdown areas or outdoor locations. The accelerometer's ±50 g measurement range suits most rotating equipment without risk of saturation during normal operation.

Installation and Setup Guidance

Mount the 200355-09-00-00 using the 1/4-28 female thread with a torque of 2 to 5 ft-lb (2.7 to 6.8 N-m). Ensure the mounting surface is clean and flat for optimal frequency response. Connect the 2-pin Mil-C-5015 connector to a suitable data acquisition system that provides 18–28 VDC excitation and 2–20 mA constant current. Allow at least 2.0 seconds settling time after power-up before taking measurements.

Routine Maintenance and Reliability

Periodically inspect the cable and connector for damage, especially in high-vibration or corrosive environments. Verify the output bias voltage remains between 8 and 12 VDC to confirm the sensor is functioning correctly. The welded hermetic stainless steel construction minimizes maintenance needs, but regular calibration checks every 12–24 months help maintain measurement accuracy.

Compatibility and Integration

The 200355-09-00-00 is a standard IEPE-type accelerometer compatible with most industrial vibration monitoring systems that supply constant current excitation. Its 100 mV/g sensitivity is a common industry standard, making it easy to integrate into existing Bently Nevada or third-party monitoring networks.
