Real-World Applications for the 200350-12-00-01

This accelerometer excels in continuous vibration monitoring on pumps, fans, compressors, and motors. In oil and gas facilities, its CSA, ATEX, and IECEx agency approvals make it suitable for hazardous areas. The stainless steel housing and welded hermetic seal withstand corrosive environments. By integrating this sensor into a condition monitoring system, maintenance teams can detect bearing wear or imbalance early, preventing unplanned downtime.

Installation & Setup Guide

Mount the 200350-12-00-01 using the M8x1.25 adhesive stud mount (option 12) or the 1/4-28 female thread. Apply a maximum mounting torque of 2 to 5 ft-lb (2.7 to 6.8 N-m). The top-mounted 2-pin Mil-C-5015 connector simplifies wiring. Ensure excitation voltage between 18 and 28 VDC and constant current of 2 to 20 mA. Allow a settling time of 2.0 seconds within 1% of bias before taking measurements. For best results, follow the manufacturer's installation manual.

Maintenance & Reliability Tips

Routine inspection of the 200350-12-00-01 includes verifying the connector integrity and checking for physical damage. The welded hermetic seal and stainless steel construction minimize corrosion risk. In condensing humidity environments, the IP68 rating ensures internal components stay dry. Regular calibration checks against a known reference maintain measurement accuracy. For critical machinery, schedule periodic verification per the OEM's guidelines to extend service life.
