Real-World Applications for the 200155-09-05

This accelerometer excels in fin-fan applications and on slow rotating shafts where traditional sensors may miss critical low-frequency vibrations. It is also suitable for cooling tower fans, large diameter bearings, and other machinery operating below 600 rpm. The multiple approvals (CSA, ATEX, and IECEx) allow deployment in hazardous areas without additional certification work.

Installation and Mounting Guide for the 200155-09-05

Mount the 200155-09-05 using the 3/8-24 female thread and tighten to 2.7 to 6.8 N•m (2 to 5 ft•lbf). The 09 mounting stud option provides a 3/8-24 to 3/4 NPT adapter with a 1-1/4 inch hex stud for secure attachment. Ensure the mounting surface is clean and flat to achieve the specified hermetic seal. After installation, allow 24 hours cure time before full operation.

Maintenance and Reliability of the 200155-09-05

Routine inspection of the cable and connector integrity helps maintain reliable data transmission. The 316L stainless steel housing and hermetic sealing protect against moisture and corrosive environments. Periodic verification of output bias voltage ensures the sensor remains within specification. For optimal longevity, avoid exceeding the axial shock limit of 49,050 m/s² pk.
