Bently Nevada 200157-01-05 Enveloping Trendmaster Pro Accelerometer

Product Overview

This sensor is designed for roller element bearing analysis and detecting certain cavitation effects.

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

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). AutoDCSTech stocks this model and can confirm current availability and lifecycle status.
