200355-01-00-00 | Bently Nevada 100 mV/g Accelerometer 200350 Series

Introduction to the Bently Nevada 200355-01-00-00 Accelerometer

When machinery vibration threatens uptime, the 200355-01-00-00 from Bently Nevada provides reliable, accurate data. This 200350 series accelerometer is engineered for continuous condition monitoring in demanding industrial settings. With a sensitivity of 100 mV/g ±20% and a measurement range of ±50g, it captures both subtle and severe vibration events.

Key Features and Technical Specifications

• Sensitivity: 100 mV/g ±20% (10.2 mV/m/s² ±20%)
• Frequency Range: 30–600,000 cpm (0.5–10,000 Hz)
• Measurement Range: ±50g
• Output Bias Voltage: 8 to 12 VDC
• Excitation Voltage: 18 to 28 VDC
• Constant Current Excitation: 2 to 20 mA
• Operating Temperature: -65°F to +250°F (-54°C to +121°C)
• Enclosure Rating: IP68
• Housing Material: Stainless Steel
• Sealing: Welded Hermetic

One standout spec is the mounted resonant frequency of 1500 kcpm (25 kHz), which ensures accurate high-frequency vibration measurement. This allows early detection of bearing faults and gear mesh issues before they escalate.

Real-World Applications

In rotating machinery like pumps, motors, and compressors, the 200355-01-00-00 excels at vibration monitoring. Its IP68 rating makes it suitable for washdown environments and outdoor installations. For example, in a chemical processing plant, this accelerometer can continuously monitor pump vibration, providing early warning of imbalance or misalignment. The stainless steel housing and welded hermetic seal resist corrosion and moisture ingress.

Installation and Setup Guidance

Mount the 200355-01-00-00 using the 1/4-28 female thread with a maximum torque of 2 to 5 ft-lb (2.7 to 6.8 N-m). The mounting stud option (¼-28 to M6 x 1.00 BeCu) is included. Ensure the mounting surface is clean and flat for optimal frequency response. Connect via the 2-pin Mil-C-5015 top-mounted electrical connector. Allow 2.0 seconds settling time (within 1% of bias) after power-up before taking measurements.

Maintenance and Reliability

Routine inspection of the cable and connector integrity helps maintain reliable data. The welded hermetic seal and stainless steel construction provide long-term durability in harsh environments. Because the 200355-01-00-00 has no moving parts, it requires minimal maintenance beyond periodic visual checks. Its 100% relative humidity tolerance (condensing, non-submerged) ensures dependable operation even in wet conditions.

Compatibility and Integration

This accelerometer integrates with Bently Nevada monitoring systems and other data acquisition platforms that accept IEPE (ICP) inputs. The constant current excitation range of 2 to 20 mA and output bias voltage of 8 to 12 VDC are standard for industrial vibration sensors. Use shielded twisted-pair cable for best noise immunity.
