Industry Applications
This accelerometer suits general-purpose vibration monitoring on rotating machinery such as pumps, fans, and motors. Its robust 316L stainless steel housing and hermetic sealing make it ideal for harsh environments with high humidity or condensation. The multiple approvals (CSA, ATEX, IECEx) allow deployment in hazardous areas.
Installation & Setup Guidance
Mount the 200150-12-05 using the 3/8-24 female thread. Apply mounting torque of 2.7 to 6.8 N·m (2 to 5 ft·lbf). The mounting stud option is 3/8-24 to 1/4-20 UNC, 3/4 inch hex stud. Allow 24 hours cure time after installation. Ensure excitation voltage between 4.7 and 5.5 Vdc for proper operation.
Maintenance & Reliability
The ceramic shear sensing element and 316L stainless steel construction provide long-term stability. No routine maintenance is required beyond periodic inspection of the cable and connector. The accelerometer operates reliably from -40 °C to +105 °C.
Selection Guide & Purchasing Advice
Before ordering, verify your system requires a Trendmaster 2000 or Trendmaster Pro accelerometer with 100 mV/g sensitivity and multiple approvals. The 200150-12-05 is made in the U.S.A. and weighs 58 g (2.0 oz) typical. Contact SpareTechPLC for availability and support.
