MODEL 7502A ACCELEROMETERSPECIFICATIONSDIMENSIONS+260°C Charge Output Accelerometer
1.8pC/g output, 14kHz Bandwidth
Hermetically Sealed
Miniature, Lightweight (0.8gm)

The Model 7502A is a miniature piezoelectric charge mode
accelerometer designed for high frequency vibration andshock measurements. The accelerometer incorporates anannular shear mode crystal that provides stable thermal
response up to +260°C. The model 7502A is hermeticallysealed and features a nominal charge output of 1.8pC/g.
The miniature and light weight Titanium package rendersthe accelerometer ideal for applications requiring minimalmass loading.
