Bently Nevada 200157-18-05 Enveloping Trendmaster Pro Accelerometer

Product Introduction

When roller element bearings begin to fail or cavitation effects threaten machinery reliability, the Bently Nevada 200157-18-05 provides precise vibration monitoring. This Enveloping Trendmaster Pro accelerometer is designed for demanding industrial environments where early fault detection is critical. Manufactured in the U.S.A., it delivers reliable performance for predictive maintenance programs.

Technical Specifications Breakdown

The 200157-18-05 features a mounted resonant frequency greater than 20 kHz (>1200 kcpm), enabling detection of high-frequency vibration signals associated with bearing defects. Its quiescent current is less than 800 µA, ensuring low power consumption for continuous operation. The accelerometer is used with the ProTIM option for standard acceleration-to-velocity with acceleration enveloping channel type (-06). Multiple approvals (CSA, ATEX, and IECEx) make it suitable for hazardous area installations.

Industry Applications

This accelerometer excels in monitoring roller element bearings in rotating machinery such as motors, pumps, compressors, and turbines. It also detects certain types of cavitation effects in fluid handling equipment. The high resonant frequency allows it to capture early-stage bearing degradation before catastrophic failure occurs, reducing unplanned downtime and maintenance costs.

Installation & Setup Guidance

The 200157-18-05 includes a mounting stud option of 18 3/8-24 to M8x1 1-3/8 inch hex plate stud. Proper mounting torque and surface preparation are essential for accurate vibration measurement. Ensure the sensor is securely fastened to a flat, clean surface on the machine housing for optimal signal transmission.

Maintenance & Reliability

Routine inspection of the accelerometer and its cabling helps maintain measurement accuracy. The hermetically sealed design protects against moisture and contaminants, supporting long-term reliability in harsh conditions. Periodic verification of sensor sensitivity and bias voltage ensures consistent performance over time.

Selection Guide & Purchasing Advice

When selecting the 200157-18-05, verify compatibility with your monitoring system and the required mounting thread configuration.
