Applications & Use Cases

The 200157-10-05 excels in roller element bearing monitoring and detecting certain types of cavitation effects. Its enveloping channel type (-06) works with ProTIM option for standard acceleration-to-velocity with acceleration enveloping. This makes it ideal for predictive maintenance programs in rotating machinery.

Installation & Setup

Mount the accelerometer 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 is 10 3/8-24 to 1 NPT, 1-3/8 inch hex stud. Ensure the excitation voltage is between 4.7 and 5.5 Vdc. Allow up to 300 ms settling time after power-up.

Maintenance & Reliability

With a hermetic seal and 316L stainless steel housing, the 200157-10-05 withstands harsh environments. Its ceramic shear sensing element provides long-term stability. Inspect the mounting and cable connections periodically. The wide temperature range (-40 °C to +105 °C) ensures reliable operation in extreme conditions.

Compatibility & Integration

This accelerometer integrates with Bently Nevada monitoring systems that support acceleration enveloping. It uses a standard 4.7 to 5.5 Vdc excitation and outputs a bias voltage of +2.5 ± 0.23 Vdc. The SIG+ is positive with respect to SIG- for acceleration from base to connector.
