Why Vibration Monitoring Matters for Maintenance Engineers
For maintenance engineers, unplanned downtime is a constant threat. Vibration monitoring is a proven method to detect early signs of bearing wear, imbalance, or misalignment in rotating machinery. The Bently Nevada 200350-12-00-01 accelerometer is designed to deliver reliable data in these critical applications, helping teams shift from reactive repairs to predictive maintenance.
With a sensitivity of 100 mV/g ±20% and a frequency range of 30-600,000 cpm (0.5-10,000 Hz), this sensor captures both low-speed and high-frequency vibrations. This wide bandwidth makes it suitable for monitoring pumps, fans, compressors, and motors in demanding industrial environments.
Introducing the 200350-12-00-01 Accelerometer
Part of the Bently Nevada 200350&200355 series, the 200350-12-00-01 is a rugged accelerometer built for continuous condition monitoring. It features a ceramic shear sensing element and a welded hermetic stainless steel housing, ensuring long-term stability even in corrosive or wet conditions.
The model includes an M8x1.25 adhesive stud mount for secure installation, and its 2-Pin Mil-C-5015 top-mounted electrical connector simplifies field wiring. With an IP68 enclosure rating, this sensor withstands dust, water immersion, and 100% condensing humidity, making it a dependable choice for outdoor or washdown areas.
Key Technical Specifications for Reliable Operation
The 200350-12-00-01 delivers a measurement range of ±50g with amplitude linearity of ±1%, ensuring accurate readings across its operating envelope. Its mounted resonant frequency of 1500 kcpm (25 kHz) minimizes structural interference, while transverse sensitivity of ≤7% reduces cross-axis errors.
Electrical performance is equally robust: output bias voltage is 8 to 12 VDC, excitation voltage is 18 to 28 VDC, and constant current excitation ranges from 2 to 20 mA. The discharge time constant is ≥0.3 seconds, and settling time is 2.0 seconds within 1% of bias. These parameters support stable, repeatable measurements in continuous monitoring systems.
Real-World Application: Protecting Critical Rotating Assets
In a typical petrochemical plant, a maintenance engineer might install the 200350-12-00-01 on a large centrifugal pump handling corrosive fluids. The sensor's stainless steel housing and IP68 rating resist chemical splash and high-pressure washdown, while its 100 mV/g sensitivity captures early bearing degradation signals.
Another common use is on cooling tower fans, where the accelerometer's operating temperature range of -65°F to +250°F (-54°C to +121°C) handles extreme ambient conditions. The M8x1.25 adhesive stud mount allows quick attachment without drilling, reducing installation time and preserving equipment integrity.
Frequently Asked Questions About the 200350-12-00-01
What agency approvals does this accelerometer carry?
The 200350-12-00-01 is approved with CSA, ATEX, and IECEx certifications, as indicated by the Agency Approvals Option 01. These approvals qualify the sensor for use in hazardous locations, including potentially explosive atmospheres.
What is the mounting torque specification for this sensor?
The recommended mounting torque is 2 to 5 ft-lb (2.7 to 6.8 N-m). Proper torque ensures reliable mechanical coupling and prevents damage to the mounting thread, which is 1/4-28 female.
Can this accelerometer be used in high-humidity environments?
Yes, the sensor is rated for 100% relative humidity, condensing, non-submerged conditions. Combined with its IP68 enclosure rating and welded hermetic sealing, it performs reliably in wet, condensing environments such as paper mills or food processing plants.
