Product Introduction
When unplanned downtime threatens production targets, the Bently Nevada 200350-01-00-00 200350 Accelerometers deliver reliable vibration data to protect rotating machinery. This industrial accelerometer, manufactured by Bently Nevada and made in the U.S.A., provides precise measurements in demanding environments. With a sensitivity of 100 mV/g ±20% and a measurement range of ±50g, it captures both subtle and severe vibration events.
Technical Specifications Breakdown
Key performance parameters define the 200350-01-00-00's capabilities. The frequency range spans 30 to 600,000 cpm (0.5 to 10,000 Hz) at ±3 dB, covering low-speed to high-speed machinery. Amplitude linearity remains within ±1%, ensuring accurate readings across the full measurement range. The mounted resonant frequency reaches 1500 kcpm (25 kHz), minimizing resonance interference. Broadband electrical noise is exceptionally low at 350 μg (3,434 μm/s²), enabling detection of small vibration changes. Output bias voltage sits between 8 and 12 VDC, while excitation voltage ranges from 18 to 28 VDC with constant current excitation of 2 to 20 mA.
Industry Applications
This accelerometer excels in continuous vibration monitoring for pumps, fans, compressors, and turbines. In oil and gas facilities, its IP68 enclosure rating and welded hermetic sealing withstand moisture and corrosive atmospheres. The stainless steel housing and ceramic shear sensing element resist shock up to 5,000 g pk, making it suitable for reciprocating machinery. For power generation, the wide operating temperature range of -65°F to +250 ºF (-54°C to +121 ºC) ensures reliable performance near hot surfaces.
Installation & Setup Guidance
Mount the sensor using the 1/4-28 female thread with a mounting torque of 2 to 5 ft-lb (2.7 to 6.8 N-m). The mounting stud option 01 provides a ¼-28 to M6 x 1.00 stainless steel adapter for flexible installation. Position the electrical connector at the top and use a 2-Pin Mil-C-5015 connector for secure wiring. Allow 2.0 seconds settling time within 1% of bias after power-up before taking measurements. Ensure the discharge time constant of ≥0.3 sec is respected for accurate low-frequency response.
Maintenance & Reliability
Regularly inspect the cable and connector for damage, especially in high-vibration areas. The IP68 rating allows operation in 100% relative humidity, condensing, non-submerged conditions without performance degradation. The welded hermetic seal prevents moisture ingress, extending service life. No internal adjustments are required; periodic verification of output bias voltage (8 to 12 VDC) confirms proper operation. The 200350-01-00-00's robust design minimizes maintenance intervals, reducing total cost of ownership.
Selection Guide & Purchasing Advice
Before ordering, verify the mounting thread compatibility with your machine. The 200350-01-00-00 includes the ¼-28 to M6 x 1.00 stud; ensure your mounting point matches. Confirm the excitation voltage supply (18 to 28 VDC) and constant current (2 to 20 mA) are available. For applications requiring agency approvals, note this model carries option 00 = No Approvals. Contact SpareTechPLC for current availability and lifecycle status before purchasing.
