Bently Nevada 200350-09-00-01 Accelerometer 100 mV/g ±20% CSA ATEX IECEx

Product Overview

When machinery vibration threatens uptime, the Bently Nevada 200350-09-00-01 accelerometer delivers precise, reliable data. This 200350 series sensor provides a sensitivity of 100 mV/g ±20% (10.2 mV/m/s² ±20%) and operates across a frequency range of 30-600,000 cpm (0.5-10,000 Hz). Designed for harsh industrial environments, it carries CSA, ATEX, and IECEx agency approvals, ensuring safe use in hazardous areas.

Technical Specifications Breakdown

The 200350-09-00-01 offers a measurement range of ±50 g with transverse sensitivity ≤7% and amplitude linearity ±1%. Its mounted resonant frequency reaches 1500 kcpm (25 kHz), while broadband electrical noise (1-10 kHz) is only 350 μg (3,434 μm/s²). Output bias voltage ranges from 8 to 12 VDC, requiring an excitation voltage of 18 to 28 VDC with constant current excitation of 2 to 20 mA. Settling time is 2.0 seconds within 1% of bias, output impedance is less than 150 ohms, and the discharge time constant is ≥0.3 seconds. Electrical isolation from the case exceeds 108 ohms.

Industry Applications

This accelerometer excels in rotating machinery monitoring for pumps, motors, fans, compressors, and turbines. Its IP68 enclosure rating allows continuous operation in condensing humidity and non-submerged wet environments. The stainless steel housing and welded hermetic sealing protect against corrosion and contamination, making it ideal for oil and gas, chemical processing, power generation, and water treatment facilities. Compared to lower-rated sensors, the 200350-09-00-01 provides superior accuracy and durability in demanding conditions.

Installation & Setup Guidance

Mount the accelerometer using the 1/4-28 female thread with a maximum torque of 2 to 5 ft-lb (2.7 to 6.8 N-m). The 2-pin Mil-C-5015 electrical connector is positioned at the top for easy wiring. Ensure the mounting surface is clean and flat to achieve optimal frequency response. No mounting stud is included (option 09), so use a suitable stud or adhesive mount if required. Verify excitation voltage and constant current settings match the sensor's requirements before powering up.

Maintenance & Reliability

The ceramic shear sensing element and stainless steel construction provide long-term stability. The welded hermetic seal prevents moisture ingress, supporting the IP68 rating. Operating temperature range is -65°F to +250 °F (-54°C to +121 °C), and shock survivability is 5,000 g peak. Relative humidity tolerance is 100% condensing, non-submerged. Regular inspection of the connector and cable for damage ensures continued performance. No specific cleaning procedures are recommended for safety-rated equipment; follow the manufacturer's guidelines for periodic verification.

Selection Guide & Purchasing Advice

When selecting the 200350-09-00-01, confirm the hex size (11/16" or 1.8 cm), height (1.65" or 4.24 cm), and weight (0.051 kg) fit your installation space. This model includes agency approvals for CSA, ATEX, and IECEx, making it suitable for explosive atmospheres. For complete technical specifications and availability, contact BluePLC Industrial.
