Model 997 Series High Frequency Integral Cable Accelerometer

Brand: Wilcoxon Sensing Technologies
Request Information
High frequency accelerometers are ideal for applications involving high speed components such as machine tool spindles, compressors, and turbines. These applications often include gear mesh frequencies with higher harmonics or blade pass frequencies exceeding 60,000 CPM. 

Wilcoxon’s high frequency 997 series sensors offer 10 mV/g sensitivity, preventing sensor overload. Sensors with 10 mV/g output are most commonly used due to their high amplitude range (600 g) which can be present in high speed applications. Typically there is little measurable vibration in terms of displacement and velocity at high frequency; however tremendous amounts of acceleration may be present.
Features
  • Corrosion resistant
  • Hermetically sealed
  • ESD-protected
  • Reverse wiring protection
  • Internal ring offers extra isolation
  • IP67 integral cable
  • Manufactured in an approved ISO 9001 facility
