Bently Nevada 200350-12-00-CN Accelerometer: 100 mV/g, IP68, Ceramic Shear

Technical Specifications Breakdown

Key parameters for the 200350-12-00-CN are listed below for quick reference:

Industry Applications

Use it for:

• Rotating Machinery Monitoring: Detect early bearing faults and imbalance in pumps, compressors, and turbines. The wide frequency range (30-600,000 cpm) captures both low-speed and high-frequency vibrations.
• Harsh Environment Installations: With an IP68 enclosure rating and 100% relative humidity tolerance (condensing, non-submerged), this sensor performs reliably in washdown areas, outdoor installations, and humid process plants.
• Predictive Maintenance Programs: The ±1% amplitude linearity ensures accurate trend data for condition-based maintenance, reducing unplanned downtime.

Installation & Setup Guidance

Mount the accelerometer using the 1/4-28 female mounting thread. Apply a mounting torque of 2 to 5 ft-lb (2.7 to 6.8 N-m) to ensure proper coupling. For adhesive mounting, use the M8x1.25 adhesive stud (option 12). Connect via the 2-Pin Mil-C-5015 top-mounted connector. Ensure excitation voltage is between 18 to 28 VDC with constant current excitation of 2 to 20 mA. Allow a settling time of 2.0 seconds (within 1% of bias) after power-up before taking measurements.

Maintenance & Reliability

Inspect the accelerometer periodically for physical damage, connector corrosion, or cable wear. The welded hermetic seal and stainless steel housing provide protection against moisture and contaminants. The sensor can survive shocks up to 5,000 g pk, making it robust for industrial environments. No internal calibration is required; verify system performance by checking output bias voltage (8 to 12 VDC) during routine checks.

Reliable Vibration Sensing for Critical Machinery

The Bently Nevada 200350-12-00-CN accelerometer delivers precise vibration data for rotating equipment protection. Designed for continuous monitoring in demanding industrial environments, this sensor provides a sensitivity of 100 mV/g ±20% with a measurement range of ±50g. Its ceramic shear sensing element and welded hermetic stainless steel housing ensure long-term stability and durability.

Compatibility & Integration

The 200350-12-00-CN accelerometer is compatible with Bently Nevada vibration monitoring systems that accept standard IEPE (Integrated Electronics Piezo-Electric) inputs. The output impedance is less than 150 ohms, allowing connection to most data acquisition modules. The discharge time constant of ≥0.3 sec ensures accurate low-frequency response.

Selection Guide & Purchasing Advice

When selecting an accelerometer, consider the sensitivity, frequency range, and environmental rating. The 200350-12-00-CN offers a balanced combination of sensitivity (100 mV/g), wide bandwidth, and rugged construction.

Troubleshooting & Common Issues

• No Output Signal: Check excitation voltage (18-28 VDC) and constant current (2-20 mA). Verify cable integrity and connector pin continuity.
• Erratic Readings: Inspect for loose mounting or damaged cable. Ensure the mounting torque is within 2-5 ft-lb. Confirm the sensor is not saturated (vibration levels within ±50g).
• Bias Voltage Out of Range: The output bias voltage should be 8 to 12 VDC. If outside this range, the sensor may be damaged or the power supply may be faulty. Replace the unit if necessary.
