200157-02-05 | Bently Nevada 10.2 mV/(m/s²) Enveloping Trendmaster Pro Accelerometer

Introduction to the Bently Nevada 200157-02-05

When roller element bearings begin to fail or cavitation effects threaten rotating machinery, the 200157-02-05 from Bently Nevada provides the early warning you need. This Enveloping Trendmaster Pro Accelerometer is engineered for condition monitoring applications where acceleration enveloping reveals fault signatures before catastrophic damage occurs. With a sensitivity of 10.2 mV/(m/s²) at 80 Hz, it captures subtle vibration changes that standard sensors might miss.

Key Features & Technical Specs of the 200157-02-05

• Sensitivity: 10.2 mV/(m/s²) (±12%) at 80 Hz — ensures consistent, repeatable measurements.
• Measurement Range: ±245 m/s² (±25 g) — covers the full dynamic range of industrial vibration.
• Frequency Range: 10 to 10,000 Hz (600 to 600,000 cpm) — ideal for bearing and gearmesh monitoring.
• Mounted Resonant Frequency: >20 kHz (>1200 kcpm) — avoids interference in high-frequency applications.
• Amplitude Linearity: ±2% (1 to 10 g pk) — delivers accurate amplitude tracking.
• Transverse Sensitivity: ≤7% — minimizes cross-axis errors.
• Settling Time: ≤300 ms — quick stabilization after power-up.
• Excitation Voltage: 4.7 to 5.5 Vdc — compatible with standard data collectors.
• Output Bias Voltage: +2.5 ± 0.23 Vdc — simplifies interface with monitoring systems.
• Temperature Range: -40 °C to +105 °C (-40 °F to +221 °F) — suitable for harsh environments.

Applications & Use Cases for the 200157-02-05

In pulp and paper mills, the 200157-02-05 monitors dryer roll bearings where enveloping detects early spalling. For petrochemical plants, it tracks pump cavitation by isolating high-frequency acceleration bursts. Similarly, in mining conveyors, the accelerometer identifies bearing defects before they cause unplanned downtime. Its shear sensing geometry and ceramic element provide reliable data even in condensing humidity up to 100% relative humidity.

Installation & Setup of the Bently Nevada 200157-02-05

Mount the 200157-02-05 using the 3/8-24 female thread with a torque of 2.7 to 6.8 N·m (2 to 5 ft·lbf). The 3/8-24 to 3/8-24 UNF hex plate stud option (mounting stud option 02) simplifies attachment. Allow 24 hours cure time for thread-locking compound if used. Ensure the base-to-connector polarity (SIG+ positive) matches your data acquisition system.

Maintenance & Reliability Tips

Inspect the 200157-02-05 annually for cable integrity and connector cleanliness. Verify output bias voltage stays within +2.5 ± 0.23 Vdc — drift may indicate sensor degradation. The hermetically sealed housing (5x10⁻⁸ atm·cc/s max leak rate) protects against moisture ingress, but periodic visual checks of the 316L stainless steel housing are recommended. For safety-rated equipment, always follow the manufacturer’s manual for inspection intervals.
