A distinctive spec is the axial shock limit of 49,050 m/s² pk (5,000 g pk), ensuring the sensor withstands harsh impacts without damage.

Applications and Use Cases

The 200150-02-05 excels in general vibration monitoring for rotating machinery such as pumps, fans, and motors. Its wide frequency range covers common fault frequencies, enabling early detection of imbalance, misalignment, or bearing wear. For example, in a continuous process plant, this accelerometer helps reduce unplanned downtime by providing reliable data for condition-based maintenance.

Installation and 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 02 specifies a 3/8-24 to 3/8-24 UNF 1-3/8 inch hex plate stud. Ensure the surface is clean and flat for optimal coupling. Allow 24 hours cure time if adhesive mounting is used. The settling time is ≤300 ms within 5% of bias voltage.

Maintenance and Reliability

Routine inspection of the sensor and cable connections helps maintain signal integrity. The hermetically sealed design (5×10⁻⁸ atm·cc/s maximum) protects against moisture and contaminants, supporting reliable operation in condensing humidity environments. Periodic verification of output bias voltage ensures the sensor remains within specification.

Compatibility and Integration

The 200150-02-05 works with Bently Nevada ProTIM option standard acceleration-to-velocity channel type (-01). It is suited for general application monitoring systems. For integration details, refer to the system manual or contact Petro Auto Tech.
