200355-12-00-00 | Bently Nevada 100 mV/g Accelerometer

Introduction to the 200355-12-00-00

When industrial machinery demands precise vibration monitoring, the 200355-12-00-00 from Bently Nevada steps in as a reliable solution. This accelerometer is part of the 200350 series, designed for continuous condition monitoring in harsh environments. With a sensitivity of 100 mV/g ±20% and a measurement range of ±50g, it captures subtle vibrations and high-impact events alike. The unit operates across a frequency range of 30 to 600,000 cpm (0.5 to 10,000 Hz), making it suitable for rotating equipment such as pumps, motors, and turbines. Its robust stainless steel housing and welded hermetic sealing ensure durability in challenging industrial settings.

Key Features and Technical Specifications

• Sensitivity: 100 mV/g ±20% (10.2 mV/m/s² ±20%)
• Measurement Range: ±50g
• Frequency Range: 30 to 600,000 cpm (0.5 to 10,000 Hz)
• 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

A standout feature is the 200355-12-00-00's transverse sensitivity of ≤7%, which minimizes cross-axis errors for accurate vibration readings. This ensures reliable data for predictive maintenance programs.

Real-World Applications

In petrochemical plants, the 200355-12-00-00 monitors pump vibrations to prevent unplanned downtime. Similarly, power generation facilities use it for turbine health tracking. Its IP68 rating allows deployment in condensing, non-submerged environments with 100% relative humidity. The accelerometer's ceramic shear sensing element provides stable performance over a wide temperature range, making it ideal for outdoor installations.

Installation and Setup Guidance

Mount the 200355-12-00-00 using the M8x1.25 adhesive stud mount (included with the -12 option). Apply a mounting torque of 2 to 5 ft-lb (2.7 to 6.8 N-m) to the 1/4-28 female thread. Connect via the 2-pin Mil-C-5015 top-mounted electrical connector. Ensure the excitation voltage is between 18 and 28 VDC with a constant current of 2 to 20 mA. Allow a settling time of 2.0 seconds within 1% of bias after power-up for stable output.

Maintenance and Reliability

Periodically inspect the 200355-12-00-00 for physical damage or corrosion, especially in condensing environments. The welded hermetic seal protects internal components, but verify the electrical connector is clean and secure. With a shock survivability of 5,000 g pk, this accelerometer withstands accidental impacts. Routine checks of the output bias voltage (8 to 12 VDC) confirm proper operation.
