A standout feature is the enveloping channel type, which extracts low-energy impact signals from background noise. This makes the 200157-06-05 ideal for detecting early-stage bearing defects that standard accelerometers might miss.

Real-World Applications for the 200157-06-05

Engineers rely on the 200157-06-05 in rotating machinery monitoring, particularly for roller element bearings and cavitation effects in pumps. Its rugged design withstands harsh industrial environments, including 100% condensing humidity and axial shock up to 49,050 m/s² pk (5,000 g pk). The ceramic shear sensing element ensures stable performance over time.

Installation Guide for the 200157-06-05 Accelerometer

Mount the 200157-06-05 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 stud option 06 provides a 3/8-24 to 1/4 NPT adapter with a 3/4 inch hex. Ensure the mounting surface is clean and flat for optimal frequency response. Allow 24 hours cure time if adhesive mounting is used.

Maintenance & Reliability of the 200157-06-05

Routine inspection of the 200157-06-05 involves checking cable integrity and connector tightness. The hermetically sealed 316L stainless steel housing protects against moisture and contaminants. With proper installation, the sensor delivers consistent data over long service intervals, reducing total cost of ownership.

Compatibility & Integration

The 200157-06-05 works with Bently Nevada ProTIM options for standard acceleration-to-velocity with acceleration enveloping. It outputs a positive-going signal (SIG+ positive with respect to SIG-) and requires 4.7 to 5.5 Vdc excitation. For system integration, refer to the official Bently Nevada documentation.
