Product Overview
When you need reliable vibration monitoring for critical rotating machinery, the Bently Nevada 200157-01-05 Enveloping Trendmaster Pro accelerometer delivers precise data. This sensor is designed for roller element bearing analysis and detecting certain cavitation effects. It integrates seamlessly with the ProTIM option for standard acceleration-to-velocity with acceleration enveloping channel type (-06).
Technical Specifications Breakdown
The 200157-01-05 offers a sensitivity of 10.2 mV/(m/s²) (100 mV/g) at 80 Hz, with a measurement range of ±245 m/s² (±25 g). Its frequency range spans 10 to 10,000 Hz (600 to 600,000 cpm), referenced to 80 Hz. The mounted resonant frequency exceeds 20 kHz, ensuring accurate readings in high-frequency applications. Amplitude linearity is within ±2% (1 to 10 g pk), and transverse sensitivity is ≤7%. The accelerometer settles within 5% of bias in ≤300 ms.
Industry Applications
This accelerometer is ideal for monitoring roller element bearings in pumps, motors, compressors, and turbines. It also detects cavitation effects in fluid handling equipment. The enveloping capability highlights early-stage bearing faults, allowing predictive maintenance that reduces unplanned downtime.
Installation & Setup Guidance
Mount the 200157-01-05 using the 3/8-24 female thread with a mounting torque of 2.7 to 6.8 N•m (2 to 5 ft•lbf). The mounting stud option includes 3/8-24 thread and two adhesive mount frames with adhesive. Ensure proper surface preparation and cure time of 24 hours for adhesive mounts. The sensor is hermetically sealed to 5x10⁻⁸ atm•cc/s, suitable for harsh environments.
Maintenance & Reliability
Regular inspection of the mounting integrity and cable connections is recommended. The accelerometer operates from -40°C to +105°C and withstands axial shock up to 49,050 m/s² pk (5,000 g pk). Its 316L stainless steel housing and ceramic shear sensing element ensure long-term reliability in corrosive and humid conditions (100% relative, condensing, non-submerged).
Selection Guide & Purchasing Advice
Before purchasing the 200157-01-05, verify your system's excitation voltage (4.7 to 5.5 Vdc) and ensure compatibility with your monitoring equipment. The 200157-01-05 includes multiple approvals (CSA, ATEX, and IECEx). SpareTechPLC stocks this model and can confirm current availability and lifecycle status.
