Bently Nevada 200157-17-05 Enveloping Trendmaster Pro Accelerometer Guide

Product Introduction

When roller element bearing failures threaten production uptime, the Bently Nevada 200157-17-05 Enveloping Trendmaster Pro accelerometer provides a reliable solution. This sensor is engineered for detecting early signs of bearing wear and certain cavitation effects in rotating machinery. As part of the Trendmaster Pro family, it delivers precise acceleration measurements to support predictive maintenance programs.

Technical Specifications Breakdown

The 200157-17-05 features a mounted resonant frequency exceeding 20 kHz (>1200 kcpm), ensuring high-frequency response capability for early fault detection. Its quiescent current is less than 800 µA, indicating low power consumption suitable for continuous monitoring systems. The mounting stud option (17 3/8-24 to 3/8-16 UNC 1-3/8 inch hex plate stud) provides flexible installation on various machine surfaces. Multiple approvals (CSA, ATEX, and IECEx) confirm its suitability for hazardous environments.

Industry Applications

This accelerometer excels in roller element bearing monitoring across industries such as oil and gas, power generation, and manufacturing. For example, in a refinery, the 200157-17-05 can detect early-stage bearing degradation in pumps and compressors, enabling scheduled maintenance before catastrophic failure. Its enveloping capability, used with the ProTIM option (Standard Acceleration-to-Velocity with Acceleration Enveloping channel type -06), enhances sensitivity to repetitive impact signals typical of bearing faults.

Installation & Setup Guidance

Mount the 200157-17-05 using the provided 3/8-24 female thread with a recommended torque of 2.7 to 6.8 N·m (2 to 5 ft·lbf). Ensure the mounting surface is clean and flat for optimal signal transmission. Connect the sensor to a compatible monitoring system using the appropriate cable. Allow 24 hours cure time if using adhesive mounting. Verify proper polarity (SIG+ positive with respect to SIG-) before powering up.

Maintenance & Reliability

Periodically inspect the accelerometer for physical damage or corrosion, especially in harsh environments. The hermetically sealed design (5X10-8 atm·cc/s maximum leakage) protects internal components from moisture and contaminants. Operating temperature range is -40 ºC to +105 ºC (-40 ºF to +221 ºF). For safety-critical applications, follow the manufacturer's guidelines for routine testing and calibration verification.

Selection Guide & Purchasing Advice

Before purchasing, verify that the 200157-17-05 matches your application requirements: roller element bearing monitoring with enveloping capability. Confirm compatibility with your existing monitoring system, particularly the ProTIM option. For complete technical specifications, please contact BluePLC Industrial.
