Mounting Thread: 1/4-28 Female – common for industrial stud mounts.

Mounting Torque (Maximum): 2 to 5 ft-lb (2.7 to 6.8 N-m) – ensures proper installation.

Weight: 0.051 kg – lightweight for easy mounting.

Industry Applications

This accelerometer excels in predictive maintenance programs for:

Rotating Machinery: Pumps, motors, fans, and compressors benefit from continuous vibration monitoring to detect bearing wear, imbalance, and misalignment.

Oil & Gas: Refinery equipment operating in extreme temperatures and corrosive environments rely on the IP68-rated, stainless steel construction.

Power Generation: Turbines and generators require reliable vibration data; the 200350-11-00-CN delivers consistent performance across a wide frequency range.

Installation & Setup Guidance

Proper mounting is critical for accurate readings. The accelerometer uses a 1/4-28 female thread and is supplied with an M6x1 adhesive stud mount (Mounting Stud code 11). Apply the recommended mounting torque of 2 to 5 ft-lb (2.7 to 6.8 N-m) to ensure good mechanical coupling. Use a constant current excitation source between 2 to 20 mA and verify output bias voltage of 8 to 12 VDC. The 2-Pin Mil-C-5015 connector simplifies wiring. Allow 2.0 seconds settling time after power-up for bias stabilization.

Maintenance & Reliability

The welded hermetic sealing and stainless steel housing make this accelerometer virtually maintenance-free under normal conditions. Its IP68 rating allows operation in condensing humidity and non-submerged wet environments. Periodic inspection of the cable and connector for damage is recommended. The ceramic shear sensing element offers excellent long-term stability, reducing the need for recalibration. With a mounted resonant frequency of 1500 kcpm (25 kHz), it reliably measures high-frequency vibrations without resonance interference.

Selection Guide & Purchasing Advice

Before ordering the Bently Nevada 200350-11-00-CN, verify your system's excitation voltage (18-28 VDC) and constant current range (2-20 mA). Confirm the mounting thread compatibility (1/4-28 female) and ensure the measurement range of ±50g suits your application. For complete technical specifications, contact BluePLC Industrial.
