1.0 INTRODUCTION
This specification covers the application requirements of Measurement Specialties Accelerometer ACH-04-08-05.
The accelerometer contains three piezoelectric sensing elements oriented to simultaneously measure acceleration
in three orthogonal, linear axes. Internal JFET鈥檚 provide for a low impedance, buffered output with a wide variety of
possible, application specific, signal conditioning circuitry. The sensor responds over a broad frequency range, from
below 0.5Hz to above 5kHz, as a result of the integrated electronics and the damped sensing elements.
The ACH-04-08-05 accelerometer can be used in a wide range of applications including motional measurement and
control systems, speaker feedback systems, vibration switches, shipment monitor and material handling systems,
security systems, computer input/output devices, and data loggers. The device is not IR reflow solderable.
