Bently Nevada 200355-02-00-00 200350 Accelerometer with 100 mV/g Sensitivity

Introduction: The Bently Nevada 200355-02-00-00 Accelerometer

When machinery vibration threatens uptime, the Bently Nevada 200355-02-00-00 provides reliable, high-accuracy data. This 200350 series accelerometer delivers a sensitivity of 100 mV/g ±20%, translating to 10.2 mV/m/s² ±20%. Built for demanding environments, it offers a measurement range of ±50g and a frequency range of 30-600,000 cpm (0.5-10,000 Hz). The 200355-02-00-00 is designed to capture early signs of bearing wear, imbalance, and misalignment before they cause catastrophic failure.

Technical Specifications Breakdown

The Bently Nevada 200355-02-00-00 excels in several key parameters that matter for predictive maintenance. Its sensitivity of 100 mV/g ±20% ensures consistent output across the measurement range. The ±50g measurement range accommodates both normal operation and transient events. With a frequency response from 30 to 600,000 cpm (0.5-10,000 Hz), it covers low-speed rotation up to high-frequency vibration. The mounted resonant frequency of 1500 kcpm (25 kHz) confirms its ability to capture high-frequency signals without distortion. Amplitude linearity of ±1% guarantees accuracy across the full dynamic range. Broadband electrical noise (1-10 kHz) is only 350 μg (3,434 μm/s²), preserving signal clarity even in electrically noisy environments. The output bias voltage of 8 to 12 VDC and excitation voltage of 18 to 28 VDC simplify integration with standard data collectors and monitoring systems.

Industry Applications: Solving Real Vibration Problems

In petrochemical plants, the 200355-02-00-00 monitors centrifugal pumps and compressors where high temperatures and humidity prevail. Its operating temperature range of -65°F to +250°F (-54°C to +121°C) and 100% relative humidity capability (condensing, non-submerged) make it suitable for outdoor and washdown areas. The IP68 enclosure rating ensures protection against dust and prolonged immersion. In power generation, the accelerometer tracks turbine vibrations, where the ceramic shear sensing element provides stability over time. The stainless steel housing and welded hermetic sealing resist corrosion and moisture ingress, extending service life. For paper mills, the 200355-02-00-00 handles the high shock survivability of 5,000 g pk, surviving occasional impacts from sheet breaks or roll changes.

Installation & Setup Guidance

Proper mounting is critical for accurate readings. The Bently Nevada 200355-02-00-00 uses a 1/4-28 female mounting thread and includes a mounting stud option 02 (¼-28 to M8 x 1.25 BeCu). Apply a mounting torque of 2 to 5 ft-lb (2.7 to 6.8 N-m) to ensure good mechanical coupling without over-stressing the sensor. The top-mounted 2-pin Mil-C-5015 electrical connector simplifies cable routing. Allow a settling time of 2.0 seconds (within 1% of bias) after power-up before taking measurements. The constant current excitation should be set between 2 to 20 mA, with 2 to 10 mA typical for most installations. Verify output bias voltage between 8 and 12 VDC to confirm proper operation.

Maintenance & Reliability

To maximize the lifespan of the 200355-02-00-00, perform periodic visual inspections of the cable and connector for damage. Check mounting torque annually or after any mechanical shock event. The welded hermetic seal and stainless steel housing resist corrosion, but verify the IP68 seal integrity if the sensor is submerged. The ceramic shear sensing element offers excellent long-term stability, reducing calibration drift. For safety-critical applications, follow the manufacturer's guidelines for routine testing. The discharge time constant of ≥0.3 seconds ensures accurate low-frequency measurements without DC drift. Regularly verify the output bias voltage to detect early signs of internal degradation.

Buying Guide & Selection Advice

When selecting the Bently Nevada 200355-02-00-00, confirm that the sensitivity tolerance (00 = 100 mV/g ±20%) matches your monitoring system's input requirements. The agency approvals option 00 means no approvals are included, so verify if your site requires specific certifications. The hex size is 11/16” (1.8 cm) and height is 1.65” (4.24 cm), with a weight of 0.051 kg. For complete technical specifications and current lifecycle status, please contact BluePLC Industrial.
