Solving Vibration Monitoring Challenges in Harsh Industrial Environments
When rotating machinery operates in extreme conditions, engineers face a critical problem: how to capture accurate vibration data without sensor failure. The Bently Nevada 200355-11-00-00 accelerometer directly addresses this pain point with a robust design and proven performance specs. This model from the 200350&200355 series delivers reliable measurements where humidity, temperature, and shock threaten lesser sensors.
Key Technical Specifications of the 200355-11-00-00
The 200355-11-00-00 offers a sensitivity of 100 mV/g ±20%, translating to 10.2 mV/m/s² ±20% for precise vibration amplitude detection. Its frequency range spans 30 to 600,000 cpm (0.5 to 10,000 Hz), covering low-speed to high-speed machinery monitoring needs. The measurement range of ±50 g accommodates moderate to strong vibration levels commonly found in pumps, fans, and compressors.
Engineers benefit from a mounted resonant frequency of 1500 kcpm (25 kHz), ensuring accurate readings well beyond the operating bandwidth. The output bias voltage sits between 8 and 12 VDC, while the excitation voltage requirement is 18 to 28 VDC with a constant current excitation of 2 to 20 mA. These electrical specs simplify integration with standard industrial data acquisition systems.
Built for the Toughest Conditions
One of the standout features of the 200355-11-00-00 is its IP68 enclosure rating, meaning it withstands continuous immersion in water without damage. The operating temperature range from -65°F to +250 ºF (-54°C to +121 ºC) allows deployment in freezing outdoor environments or near hot process equipment. With 100% relative humidity tolerance (condensing, non-submerged), this accelerometer thrives in washdown areas and coastal installations.
Shock survivability of 5,000 g pk ensures the sensor survives accidental impacts during installation or maintenance. The welded hermetic sealing and stainless steel housing provide long-term corrosion resistance, reducing replacement frequency in aggressive chemical or marine atmospheres.
Real-World Application: Reliable Monitoring in Condensing Humidity
Consider a food processing plant where steam cleaning creates condensing humidity around motor bearings. Standard accelerometers often fail due to moisture ingress, leading to false alarms or data gaps. The 200355-11-00-00, with its IP68 rating and 100% condensing humidity tolerance, continues delivering accurate 100 mV/g signals even after repeated washdown cycles. This reliability minimizes unplanned downtime and maintenance costs.
