Bently Nevada 200355-12-00-00 200350 Accelerometer – Reliable Vibration Sensor

Product Introduction

When unexpected vibration threatens the uptime of critical rotating machinery, the Bently Nevada 200355-12-00-00 provides the precise, reliable measurement data needed for predictive maintenance. This 200350 series accelerometer is designed for industrial environments where accuracy and durability are non-negotiable. With a sensitivity of 100 mV/g ±20% and a frequency range of 30 to 600,000 cpm (0.5 to 10,000 Hz), it captures both low-speed and high-frequency vibration signatures essential for early fault detection.

Technical Specifications Breakdown

From a maintenance engineer’s perspective, the key parameters of the 200355-12-00-00 directly impact installation ease and long-term reliability. The unit offers a measurement range of ±50 g, ensuring it can handle normal operating conditions as well as transient events. Its broadband electrical noise is exceptionally low at 350 μg (3,434 μm/s²) over 1 to 10 kHz, which means cleaner signals and fewer false alarms. The output bias voltage sits between 8 and 12 VDC, while the required excitation voltage is 18 to 28 VDC with a constant current of 2 to 20 mA. A settling time of 2.0 seconds (within 1% of bias) allows the sensor to stabilize quickly after power-up. The output impedance is less than 150 ohms, and the discharge time constant is at least 0.3 seconds. Electrical isolation from the case exceeds 108 ohms, providing excellent noise immunity. The operating temperature range spans -65°F to +250 °F (-54°C to +121 °C), and the unit can survive shock up to 5,000 g peak. Its enclosure rating is IP68, meaning it is fully protected against dust and prolonged immersion in water. The housing is made of stainless steel with welded hermetic sealing, and the electrical connector is a 2-pin Mil-C-5015 type located on top.

Industry Applications

This accelerometer is a natural fit for continuous vibration monitoring on pumps, fans, compressors, turbines, and motors in industries such as oil and gas, power generation, and manufacturing. The IP68 rating and stainless steel construction make it suitable for washdown environments or outdoor installations exposed to moisture. The M8x1.25 adhesive stud mount (option 12) simplifies installation on curved or irregular surfaces, reducing downtime during sensor deployment. For maintenance teams, the ±20% tolerance on sensitivity means predictable performance without frequent recalibration.

Installation & Setup Guidance

Mounting the 200355-12-00-00 requires attention to torque specifications: apply 2 to 5 ft-lb (2.7 to 6.8 N-m) maximum when using the 1/4-28 female mounting thread. The adhesive stud mount option (M8x1.25) is ideal for temporary or permanent attachment without drilling. Ensure the mounting surface is clean and flat to achieve optimal frequency response. The sensor’s ceramic shear sensing element provides excellent transverse rejection (≤7%), so orientation relative to the measurement axis is critical. Always verify the output bias voltage after installation to confirm proper wiring and power supply.

Maintenance & Reliability

For long-term reliability, perform periodic visual inspections of the cable and connector for signs of wear or corrosion. The welded hermetic seal and stainless steel housing eliminate the need for internal maintenance, but the external connector should be kept clean and dry. The IP68 rating allows the sensor to operate in 100% relative humidity, condensing, non-submerged conditions. If the sensor is exposed to extreme shock events, verify its output bias voltage and sensitivity to ensure it has not been damaged. No specific cleaning solvents or disassembly procedures are recommended – follow the manufacturer’s guidelines for any servicing.

Selection Guide & Purchasing Advice

Before ordering the 200355-12-00-00, confirm that the mounting stud option (12 = M8x1.25 adhesive stud mount) matches your installation requirements. The tolerance option (00 = 100 mV/g ±20%) and agency approvals option (00 = no approvals) are fixed for this part number. Verify that your data acquisition system can supply 18 to 28 VDC excitation and accept a 2 to 20 mA constant current loop.
