Bently Nevada 200350-02-00-CN Accelerometer: High-Performance Vibration Sensor

Why Choose the Bently Nevada 200350-02-00-CN for Vibration Monitoring?

When unplanned downtime threatens production lines, the Bently Nevada 200350-02-00-CN accelerometer provides the reliable vibration data needed to detect early faults. This industrial-grade sensor, part of the 200350 Accelerometers series, delivers precise measurements in demanding conditions.

Product Overview

The Bently Nevada 200350-02-00-CN is a piezoelectric accelerometer designed for permanent vibration monitoring on rotating machinery. Manufactured in the U.S.A., it features a ceramic shear sensing element and a welded hermetic stainless steel housing for long-term durability. The sensor includes a 2-Pin Mil-C-5015 top electrical connector and a 1/4-28 female mounting thread. With a mounting stud option of ¼-28 to M8 x 1.25 BeCu, it offers flexible installation choices.

Industry Applications

This accelerometer excels in continuous vibration monitoring for pumps, fans, compressors, and turbines. In oil and gas facilities, the ±50g measurement range captures both normal operation and transient events. The IP68 rating allows submersion in condensing humidity, making it suitable for washdown environments in food processing or marine applications. The wide frequency range (0.5–10,000 Hz) covers low-speed to high-speed machinery, enabling early bearing fault detection.

Installation & Setup Guidance

Mount the sensor using the 1/4-28 female thread with a maximum torque of 2 to 5 ft-lb (2.7 to 6.8 N-m). Ensure the mounting surface is clean and flat for optimal signal transfer. Connect the 2-Pin Mil-C-5015 top connector to a compatible data acquisition system. For best performance, use a constant current excitation source between 2 and 20 mA and an excitation voltage of 18 to 28 VDC. Allow 2.0 seconds settling time after power-up before taking measurements.

Maintenance & Reliability

The welded hermetic stainless steel housing and ceramic sensing element provide excellent resistance to moisture and corrosion. The 100% condensing humidity rating ensures reliable operation in wet conditions. Regular inspection of the cable and connector for damage is recommended. No internal adjustments are required; the sensor is sealed and maintenance-free under normal use.
