Industry Applications
This accelerometer excels in monitoring pumps, fans, compressors, and motors in industries like oil and gas, power generation, and manufacturing. Its ATEX and IECEx approvals allow installation in potentially explosive atmospheres. For example, in a refinery, the 200150-23-05 continuously tracks vibration on critical pumps, enabling early detection of bearing wear and reducing unplanned shutdowns.
Installation & Setup Guidance
Proper mounting ensures accurate readings. Use the 3/8-24 female thread with the provided stud option 23. Apply the specified torque of 2.7 to 6.8 N•m (2 to 5 ft•lbf) to secure the sensor. Ensure the mounting surface is clean and flat. Connect the excitation voltage of 4.7 to 5.5 Vdc and verify the output bias voltage of +2.5 ± 0.23 Vdc. Allow 24 hours cure time if adhesive mounting is used.
Maintenance & Reliability
The hermetically sealed 316L stainless steel housing protects against moisture and contaminants. With an axial shock limit of 5,000 g pk, the sensor withstands mechanical shocks. Regular inspection of the cable and connector ensures signal integrity. Given its robust design, the accelerometer requires minimal maintenance, reducing total cost of ownership.
