7530A Series Accelerometer

Description: The Model 7530A is a triaxial piezoelectric charge mode accelerometer designed for high frequency vibration and shock measurements. The accelerometer incorporates three independent annular shear mode crystal assemblies installed with a compression ring that eliminates the usage of epoxies that can affect long term stability at elevated temperatures. The annular shear crystals also provide a stable thermal response up to 200°C and a nominal charge output of 5.6pC/g which offers optimum signal to noise ratio.

Features:

  • Triaxial Charge Output Accelerometer
  • 5.6pC/g Charge Output
  • Hermetically Sealed
  • Wide Bandwidth to >6kHz
  • -73° to 200°C Operating Range
  • Annular Shear Mode Crystals
  • Stable Temperature Response
