Industry Trends in Vibration Monitoring
Industrial machinery increasingly relies on condition-based maintenance to reduce unplanned downtime. Vibration monitoring has become a cornerstone of predictive maintenance strategies across sectors like oil and gas, power generation, and manufacturing. The demand for high-performance accelerometers continues to grow as plants seek to extend equipment life and improve safety.
Modern accelerometers must deliver accurate data across wide frequency ranges and harsh environments. The Bently Nevada 200355-00-00-00 meets these requirements with robust specifications designed for continuous operation.
Introducing the 200355-00-00-00
When engineers need reliable vibration data from rotating machinery, the Bently Nevada 200355-00-00-00 provides a proven solution. This accelerometer is part of the 200350&200355 series and is manufactured in the U.S.A. It offers a sensitivity of 100 mV/g ±20% and a frequency range of 30-600,000 cpm (0.5-10,000 Hz), making it suitable for a wide variety of machine monitoring applications.
The 200355-00-00-00 features a ceramic shear sensing element housed in a stainless steel body with welded hermetic sealing. Its IP68 enclosure rating ensures reliable performance even in condensing humidity environments. The top-mounted 2-pin Mil-C-5015 electrical connector simplifies installation.
Technical Specifications and Performance
The 200355-00-00-00 delivers a measurement range of ±50 g with amplitude linearity of ±1%. Its mounted resonant frequency reaches 1500 kcpm (25 kHz), enabling detection of high-frequency vibration events. Broadband electrical noise is specified at 350 μg (3,434 μm/s²) over the 1-10 kHz range, ensuring clean signals for analysis.
Output bias voltage is 8 to 12 VDC, and the device requires an excitation voltage of 18 to 28 VDC with constant current excitation between 2 and 20 mA. Settling time within 1% of bias is 2.0 seconds, and output impedance is less than 150 ohms. The discharge time constant is ≥0.3 seconds, and electrical isolation from the case exceeds 108 ohms.
Operating temperature spans -65°F to +250 ºF (-54°C to +121 ºC), and the accelerometer can survive shock up to 5,000 g peak. The mounting thread is 1/4-28 female, with a recommended mounting torque of 2 to 5 ft-lb (2.7 to 6.8 N-m). The unit weighs 0.051 kg and has a height of 1.65 inches (4.24 cm).
Applications in Modern Manufacturing
In a typical petrochemical plant, the 200355-00-00-00 monitors centrifugal pumps and compressors for early signs of bearing wear or imbalance. Its wide frequency range captures both low-speed rotational issues and high-frequency gear mesh vibrations. The IP68 rating allows installation in washdown areas or outdoor locations exposed to rain and condensation.
For power generation facilities, this accelerometer provides reliable data on turbine and generator vibrations. The stainless steel construction and welded hermetic sealing resist corrosion in steam and gas environments. The 100 mV/g sensitivity offers a good balance between signal strength and measurement range for most industrial machinery.
Real-World Application Example
Consider a food processing plant with multiple cooling tower fans. The 200355-00-00-00 can be installed on fan bearing housings to detect developing faults before they cause unplanned shutdowns. Its 100% relative humidity rating and IP68 enclosure ensure reliable operation in the moist environment. The 2-pin Mil-C-5015 connector provides a secure, industry-standard interface for data acquisition systems.
Frequently Asked Questions About the 200355-00-00-00
What is the sensitivity of the 200355-00-00-00 accelerometer?
