200350-09-00-CN | Bently Nevada 100 mV/g ±20% Accelerometer

Introduction to the Bently Nevada 200350-09-00-CN Accelerometer

When industrial machinery demands precise vibration monitoring, the 200350-09-00-CN from Bently Nevada provides accurate data. This accelerometer is part of the 200350 series and is designed for continuous condition monitoring. With a sensitivity of 100 mV/g ±20%, it captures subtle vibrations across a wide frequency range. The device is built to withstand extreme conditions, making it a reliable choice for critical assets.

Key Features and Technical Specifications

• Sensitivity: 100 mV/g ±20% (10.2 mV/m/s² ±20%)
• Frequency Range: 30 to 600,000 cpm (0.5 to 10,000 Hz) at ±3 dB
• Measurement Range: ±50 g
• 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
• Mounting Thread: 1/4-28 Female
• Housing Material: Stainless Steel

The 200350-09-00-CN uses a ceramic shear sensing element for accurate readings. Its welded hermetic sealing ensures long-term reliability in condensing humidity environments. The top-mounted 2-pin Mil-C-5015 connector simplifies installation.

Applications and Use Cases

This accelerometer is ideal for rotating machinery monitoring in industries such as oil and gas, power generation, and manufacturing. It excels in applications where high shock survivability (5,000 g pk) and wide temperature tolerance are required. For example, it can monitor pump vibrations in a refinery, helping prevent unplanned downtime. The IP68 rating allows submersion in non-submerged condensing conditions, expanding its use to washdown areas.

Installation and Setup

Mount the 200350-09-00-CN 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 no-mounting-stud option (code 09) requires a compatible stud or adapter. Ensure the excitation voltage stays between 18 and 28 VDC and constant current between 2 and 20 mA. Allow 2.0 seconds settling time within 1% of bias before taking readings.

Maintenance and Reliability

Regular inspection of the connector and cable helps maintain signal integrity. The welded hermetic seal protects internal components from moisture and contaminants. With a broadband electrical noise of only 350 μg (3,434 μm/s²) from 1 to 10 kHz, this accelerometer delivers clean data for analysis. Its stainless steel housing resists corrosion in harsh environments.
