200350-12-00-00 | Bently Nevada 100 mV/g Accelerometer

Introduction to the Bently Nevada 200350-12-00-00 Accelerometer

When vibration monitoring demands high accuracy in extreme conditions, the 200350-12-00-00 from Bently Nevada provides reliable performance. This accelerometer is part of the 200350 series, designed for industrial machinery protection and condition monitoring. With a sensitivity of 100 mV/g ±20%, it captures subtle vibration changes that signal developing faults.

The 200350-12-00-00 features a ceramic shear sensing element and welded hermetic stainless steel housing, ensuring durability in condensing humidity and temperatures from -65°F to +250°F (-54°C to +121°C). Its IP68 enclosure rating allows operation in submerged conditions, making it suitable for pumps, compressors, and rotating equipment in harsh environments.

Key Features and Technical Specifications

• Sensitivity: 100 mV/g ±20% (10.2 mV/m/s² ±20%)
• Frequency Range: 30-600,000 cpm (0.5-10,000 Hz) ±3 dB
• Measurement Range: ±50 g
• Broadband Electrical Noise (1-10 kHz): 350 μg (3,434 μm/s²)
• Output Bias Voltage: 8 to 12 VDC
• Excitation Voltage: 18 to 28 VDC
• Constant Current Excitation: 2 to 20 mA
• Operating Temperature: -65°F to +250°F (-54°C to +121°C)
• Enclosure Rating: IP68
• Weight: 0.051 kg

A standout specification is the mounted resonant frequency of 1500 kcpm (25 kHz), which extends the usable frequency range for detecting high-frequency impacts and gear mesh vibrations. This makes the 200350-12-00-00 particularly effective for early fault detection in high-speed machinery.

Real-World Applications

Maintenance engineers rely on the 200350-12-00-00 for continuous vibration monitoring of critical assets. In oil and gas facilities, it withstands condensing humidity and temperature extremes while delivering accurate data. For water treatment plants, the IP68 rating allows installation in wet environments without failure. The accelerometer's 100 mV/g sensitivity is ideal for detecting imbalance, misalignment, and bearing wear in pumps and fans, helping reduce unplanned downtime.

Installation and Setup

Mount the 200350-12-00-00 using the M8x1.25 adhesive stud mount (included with the 12 mounting stud option). Apply a mounting torque of 2 to 5 ft-lb (2.7 to 6.8 N-m) to the 1/4-28 female thread. Ensure the mounting surface is clean and flat for optimal signal transmission. The 2-pin Mil-C-5015 connector provides a secure electrical connection. Allow at least 2.0 seconds settling time after power-up for the output bias voltage to stabilize within 1% of its final value.

Maintenance and Reliability

Regular inspection of the 200350-12-00-00 ensures long-term reliability. Check the electrical connector for corrosion or damage, especially in condensing environments. Verify the output bias voltage remains between 8 and 12 VDC during operation. The welded hermetic seal protects internal components from moisture, but periodic visual inspection of the housing is recommended. With proper care, this accelerometer provides years of consistent vibration data, reducing total cost of ownership.
