Applications and Use Cases for 200155-13-05

The 200155-13-05 excels in fin-fan and slow rotating shaft applications. It monitors vibration on cooling tower fans, agitators, and other low-speed equipment. Its hermetically sealed design withstands harsh industrial environments. The device operates reliably in temperatures from -40 °C to +105 °C. This makes it suitable for outdoor and process-critical installations.

Installation and Mounting Guidance

Mount the 200155-13-05 using the 3/8-24 female thread. Apply a mounting torque of 2.7 to 6.8 N·m (2 to 5 ft·lbf). The mounting stud option (13) is a 3/8-24 to 5/16-18 UNC, 3/4 inch hex stud. Ensure the mounting surface is clean and flat for optimal coupling. Allow 24 hours cure time for any adhesive used. Always follow the manufacturer's installation manual for best results.

Maintenance and Reliability Tips

Regular inspection of the 200155-13-05 ensures long-term reliability. Check the cable and connector for damage periodically. The 316L stainless steel housing resists corrosion in demanding environments. With a hermetic seal rating of 5×10⁻⁸ atm·cc/s maximum, the sensor maintains its integrity. This reduces the need for frequent recalibration and extends service life.

Compatibility and Integration

The 200155-13-05 works with the ProTIM Option Low Frequency Acceleration-to-Velocity channel type (-05). It is designed for use with Bently Nevada monitoring systems. The device outputs a positive signal (SIG+ positive with respect to SIG-) for acceleration from base to connector. This simplifies integration into existing vibration monitoring architectures.
