Bently Nevada 200350-09-00-00 Accelerometer: High-Reliability Vibration Sensor

Product Overview

When machinery vibration threatens uptime and safety, the Bently Nevada 200350-09-00-00 accelerometer delivers precise, reliable data for condition monitoring. This 200350 series sensor is engineered for continuous operation in demanding industrial environments, providing accurate vibration measurements from 30 to 600,000 cpm (0.5–10,000 Hz).

Manufactured in the USA, the 200350-09-00-00 features a ceramic shear sensing element housed in a stainless steel, welded hermetic enclosure rated IP68. With a sensitivity of 100 mV/g ±20% and a measurement range of ±50g, it captures both subtle and high-amplitude vibrations critical for predictive maintenance programs.

The 200350-09-00-00 uses a 2-pin Mil-C-5015 top-mounted electrical connector and a 1/4-28 female mounting thread. Recommended mounting torque is 2 to 5 ft-lb (2.7 to 6.8 N-m). The discharge time constant is ≥0.3 seconds, and output impedance is less than 150 ohms.

Industry Applications

This accelerometer excels in rotating machinery monitoring—pumps, compressors, turbines, fans, and motors. Its wide frequency response captures both low-speed and high-speed vibration signatures, enabling early detection of bearing wear, imbalance, misalignment, and gear defects.

In oil and gas, power generation, and chemical processing, the IP68 rating and stainless steel construction allow installation in washdown areas, high-humidity zones, and outdoor locations. The 100% relative humidity tolerance (condensing, non-submerged) ensures reliable performance even in condensation-prone environments.

Installation & Setup Guidance

Mount the 200350-09-00-00 directly to the machine surface using the 1/4-28 female thread. Apply a mounting torque between 2 and 5 ft-lb (2.7 to 6.8 N-m) to ensure proper coupling without damaging the sensor. Use a flat, clean surface for optimal frequency response.

Connect the 2-pin Mil-C-5015 connector to a compatible data acquisition system or vibration monitor. Provide excitation voltage between 18 and 28 VDC with constant current from 2 to 20 mA. Allow a settling time of 2.0 seconds (within 1% of bias) after power-up before taking measurements.

Maintenance & Reliability

The welded hermetic seal and stainless steel housing provide excellent resistance to moisture, dust, and corrosive atmospheres, minimizing maintenance needs. Periodically inspect the cable and connector for damage. Verify output bias voltage (8 to 12 VDC) during routine checks to confirm sensor health.

With a shock survivability of 5,000 g pk, the 200350-09-00-00 withstands accidental impacts during installation or operation. Its ceramic shear design offers long-term stability and repeatability, reducing calibration drift over time.

Selection Guide & Purchasing Advice

Before ordering, confirm that the 200350-09-00-00 matches your application requirements: sensitivity (100 mV/g), frequency range, and environmental conditions. This model has no mounting stud (option 09) and no agency approvals (option 00).
