Product Overview
When roller element bearings begin to fail or cavitation effects threaten rotating machinery, the Bently Nevada 200157-15-05 Enveloping Trendmaster Pro accelerometer delivers the precise vibration data needed for early detection. This sensor is engineered for demanding industrial environments where reliability and accuracy are non-negotiable.
Technical Specifications Breakdown
The 200157-15-05 offers a sensitivity of 10.2 mV/(m/s²) (100 mV/g) at 80 Hz, with a ±12% tolerance. Its measurement range spans ±245 m/s² (±25 g), making it suitable for a wide variety of machinery. The frequency range covers 10 to 10,000 Hz (600 to 600,000 cpm), referenced to 80 Hz, ensuring comprehensive vibration analysis. Mounted resonant frequency exceeds 20 kHz (>1200 kcpm), providing a high-frequency response for detailed diagnostics. Amplitude linearity is within ±2% (1 to 10 g pk), and transverse sensitivity is ≤7%, ensuring accurate readings even in complex vibration environments.
Industry Applications
This accelerometer excels in monitoring roller element bearings and detecting certain types of cavitation effects. In industries such as power generation, oil and gas, and manufacturing, early identification of bearing wear prevents catastrophic failures and reduces unplanned downtime. The 200157-15-05 is also effective in pump and compressor applications where cavitation can cause significant damage.
Installation & Setup Guidance
Mount the accelerometer using the 3/8-24 female thread. Apply a mounting torque of 2.7 to 6.8 N·m (2 to 5 ft·lbf). The mounting stud option includes a 15 3/8-24 to 3/8-16 UNC, 3/4 inch hex stud. Ensure the mounting surface is clean and flat for optimal coupling. The sensor requires an excitation voltage of 4.7 to 5.5 Vdc and draws a quiescent current of less than 800 µA. Output bias voltage is +2.5 ± 0.23 Vdc. Settling time is ≤300 ms within 5% of bias.
Maintenance & Reliability
The 200157-15-05 features a hermetically sealed design with a maximum leak rate of 5×10⁻⁸ atm·cc/s (3.1×10⁻⁹ atm·in³/s), protecting internal components from moisture and contaminants. It operates in 100% relative humidity (condensing, non-submerged) and withstands axial shock up to 49,050 m/s² pk (5,000 g pk). The temperature range is -40 °C to +105 °C (-40 °F to +221 °F). Regular inspection of the cable and connector for wear ensures long-term reliability.
Compatibility & Integration
The 200157-15-05 is designed for use with the ProTIM option, supporting Standard Acceleration-to-Velocity with Acceleration Enveloping channel type (-06). It integrates seamlessly with Bently Nevada monitoring systems. The accelerometer is approved for use in hazardous locations with multiple approvals: CSA, ATEX, and IECEx (approval code 05).
