Triaxial Charge Output Accelerometer+200°C Temperature Range
Hermetically Sealed
5.6pC/g Charge Output

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