Industry Applications
The 200150-03-05 accelerometer suits general applications requiring precise vibration measurement. Use it for monitoring rotating machinery such as pumps, motors, fans, and compressors. Its wide frequency range (10 to 1000 Hz) captures both low-speed and high-speed vibration signatures, enabling early fault detection. The hermetic sealing and 316L stainless steel construction allow deployment in harsh environments with high humidity or corrosive conditions.
Installation & Setup Guidance
Mount the accelerometer using the 3/8-24 female thread. Apply a mounting torque between 2.7 to 6.8 N•m (2 to 5 ft•lbf) to ensure proper coupling. The mounting stud option 03 provides a 3/8-24 to 1/2-20 UNF 1-3/8 inch hex plate stud for flexible attachment. After installation, allow a cure time of 24 hours before taking critical measurements. Connect the excitation voltage of 4.7 to 5.5 Vdc and verify the output bias voltage of +2.5 ± 0.23 Vdc.
Maintenance & Reliability
Inspect the accelerometer periodically for physical damage or contamination. The hermetic sealing (5X10⁻⁸ atm•cc/s maximum) protects internal components from moisture and contaminants. The ceramic shear sensing element provides stable performance over the temperature range of -40 ºC to +105 ºC. Regular calibration checks ensure measurement accuracy. Replace the unit if output bias voltage drifts outside the specified range.
Compatibility & Integration
This accelerometer works with Bently Nevada monitoring systems that accept standard accelerometer inputs. It is commonly paired with the ProTIM option for standard acceleration-to-velocity channel type (-01). The multiple approvals (CSA, ATEX, and IECEx) allow integration into hazardous area installations. Verify system compatibility before ordering.
Selection Guide & Purchasing Advice
Before purchasing the 200150-03-05, confirm the mounting thread requirement (3/8-24 female) and the approval class needed (05 = Multiple Approvals). Check that the excitation voltage (4.7 to 5.5 Vdc) matches your monitoring system. SpareTechPLC stocks this accelerometer and can advise on availability and lead times.
