Product Overview
When unplanned downtime threatens production targets, the Bently Nevada 200157-07-05 Enveloping Trendmaster Pro accelerometer delivers the precise vibration data needed to prevent failures. This sensor is engineered for roller element bearing monitoring and detecting certain types of cavitation effects, making it a critical component in predictive maintenance strategies. By catching early signs of wear, the 200157-07-05 helps avoid costly repairs and extends equipment life.
Technical Specifications Breakdown
The 200157-07-05 offers a sensitivity of 10.2 mV/(m/s²) (100 mV/g) at 80 Hz, ensuring accurate readings even in noisy environments. Its measurement range spans ±245 m/s² (±25 g), covering both normal operation and fault conditions. The frequency range from 10 to 10,000 Hz (600 to 600,000 cpm) captures low-speed to high-speed machinery vibrations. With a mounted resonant frequency above 20 kHz, the sensor avoids interference from structural resonances. Amplitude linearity within ±2% from 1 to 10 g pk guarantees consistent performance across the measurement range. These specs translate to reliable data that reduces false alarms and maintenance costs.
Industry Applications
In industries like oil and gas, power generation, and manufacturing, the 200157-07-05 excels at monitoring roller element bearings in pumps, motors, and compressors. For example, in a refinery, early detection of bearing degradation can prevent catastrophic failures and save thousands in downtime. The sensor also handles cavitation effects in centrifugal pumps, allowing operators to adjust conditions before damage occurs. By integrating this accelerometer into a condition monitoring system, facilities achieve higher uptime and lower spare parts inventory.
Installation & Setup Guidance
Mount the 200157-07-05 using the 3/8-24 female thread with a torque of 2.7 to 6.8 N•m (2 to 5 ft•lbf). The mounting stud option 07 provides a 3/8-24 to 3/8 NPT adapter with a 3/4 inch hex stud for secure attachment. Ensure the sensor is oriented with the acceleration direction from base to connector for correct polarity. Allow up to 300 ms settling time after power-up before taking measurements. Proper installation maximizes data accuracy and sensor lifespan, reducing the need for recalibration.
Maintenance & Reliability
The hermetically sealed housing (leak rate below 5X10⁻⁸ atm•cc/s) protects against moisture and contaminants, enabling reliable operation in 100% condensing humidity. With a temperature range of -40 ºC to +105 ºC (-40 ºF to +221 ºF), the sensor withstands harsh environments. Axial shock limit of 49,050 m/s² pk (5,000 g pk) ensures survival during accidental impacts. Regular inspection of the mounting and cable connections is recommended. This robust design minimizes replacement frequency, lowering total cost of ownership.
Compatibility & Integration
The 200157-07-05 works with the ProTIM option for standard acceleration-to-velocity with acceleration enveloping channel type (-06). It outputs a +2.5 ± 0.23 Vdc bias voltage with quiescent current under 800 µA, compatible with most Bently Nevada monitoring systems. The multiple approvals (CSA, ATEX, and IECEx) allow use in hazardous areas without additional barriers. Verify compatibility with your existing system before ordering to ensure seamless integration.
