The 200355-02-00-CN features a ceramic shear sensing element and welded hermetic sealing for long-term reliability. Its 2-pin Mil-C-5015 connector ensures secure electrical connections.

Industry Applications

This accelerometer excels in rotating machinery monitoring, such as pumps, motors, and compressors. Its high shock survivability (5,000 g pk) makes it ideal for heavy industrial environments. In petrochemical plants, the IP68 rating protects against moisture and condensation. The wide temperature range supports outdoor installations in both arctic and desert climates.

Installation & Setup

Mount the 200355-02-00-CN using the ¼-28 female thread with a torque of 2 to 5 ft-lb (2.7 to 6.8 N-m). The mounting stud option (¼-28 to M8 x 1.25 BeCu) is available for different interfaces. Ensure the mating connector is a 2-pin Mil-C-5015 type. Apply the excitation voltage between 18 and 28 VDC with a constant current of 2 to 20 mA. Allow a settling time of 2.0 seconds for bias stabilization.

Maintenance & Reliability

Regularly inspect the cable and connector for wear. The welded hermetic seal prevents moisture ingress, reducing maintenance frequency. The stainless steel housing resists corrosion in harsh chemical environments. For long-term reliability, verify the output bias voltage (8 to 12 VDC) during routine checks. The 200355-02-00-CN delivers consistent performance with minimal drift.

Compatibility & Integration

This accelerometer integrates with Bently Nevada monitoring systems and most industrial data acquisition platforms. Its 100 mV/g sensitivity matches standard vibration monitoring inputs. The top-exit 2-pin connector simplifies wiring in tight spaces. For system integration, refer to the official Bently Nevada documentation for wiring diagrams and signal conditioning requirements.

Troubleshooting & Common Issues

If the output bias voltage falls outside 8 to 12 VDC, check the excitation supply (18 to 28 VDC) and constant current (2 to 20 mA). A noisy signal may indicate grounding issues or electrical interference. Verify the mounting torque (2 to 5 ft-lb) to prevent resonance shifts. For persistent problems, consult the Bently Nevada technical support team.
