Bently Nevada 200350-01-00-01 Seismic Vibration Accelerometer

Product Overview

The 200350-01-00-01 is a premium seismic accelerometer from the Bently Nevada 200350 series, specifically engineered for vibration monitoring on rotating machinery. Utilizing a ceramic shear sensing element, this transducer provides a standard 100 mV/g sensitivity to capture critical acceleration data. Its hermetically sealed stainless steel housing and IP68 rating ensure long-term durability in high-humidity and condensing environments, making it ideal for cooling towers, pumps, and fans where precision and environmental resistance are paramount.

Technical Configuration

Model Suffix Breakdown

The 200350-01-00-01 configuration is defined by specific engineering parameters to ensure compatibility with global industrial standards:

• 200350: Series identifier for high-performance seismic accelerometers.
• -01: Mounting Stud Option (1/4-28 to M6 x 1.00 Stainless Steel).
• -00: Standard Tolerance (100 mV/g ± 20% sensitivity).
• -01: Multi-agency approvals including CSA, ATEX, and IECEx for hazardous area operation.

Technical Specifications

Installation & Maintenance Guide

The 200350-01-00-01 should be installed using the 1/4-28 to M6 mounting stud on a clean, flat surface to ensure accurate high-frequency response. Apply a mounting torque of 2–5 ft-lb (2.7–6.8 N-m) to prevent signal distortion. For electrical connection, the top-mounted 2-Pin MIL-C-5015 connector supports up to 30 meters of low-noise coaxial cable without performance degradation. Ensure the sensor is electrically isolated from the case (> 10⁸ Ω) to prevent ground loops in complex monitoring systems.

Engineering Advantages

• Exceptional Durability: Capable of surviving mechanical shocks up to 5,000 g pk with minimal deviation.
• Hazardous Area Certified: Fully compliant with ATEX, IECEx, and CSA standards for use in explosive atmospheres.
• Rapid Stabilization: Features a settling time of less than 0.2 ms, allowing for nearly instantaneous data acquisition.
• Hermetic Seal: The welded stainless steel housing prevents ingress in 100% condensing humidity environments.

Technical FAQs

Q1: What is the benefit of the Ceramic Shear sensing element?
A1: Ceramic shear technology provides better base strain and thermal transient rejection compared to compression designs, leading to more accurate vibration data in fluctuating temperatures.

Q2: Can this sensor be used at high altitudes?
A2: Yes, the 200350-01-00-01 is rated for operation at altitudes up to 12,000 ft (3,658 m) without any loss in performance.

Q3: How do I verify the output of the sensor?
A3: The module maintains an output bias voltage (OBV) of 8–12 V DC. Measuring this voltage is a quick way to confirm the sensor is powered and functioning correctly within its linear range.
