Accelerometers

The KC-2105 is a compact light weight and low cost self powered accelerometer with fast response, range 1 g to 200,000 g and has high noise rejection. The unit contains a ferroelectric material that produces a voltage when stress is applied. In order to use this characteristic to measure acceleration, an inertial mass is close coupled to the ferroelectric material. Force is transmitted to the ferroelectric material when acceleration is present in the sensitive axis producing stress that results in an output voltage. The response time is related to the resonant frequency of the sensor. This frequency is approximately 10 MHz. The high frequency is a result of the rigid structure and small size. Response time is less than 100nS.

 

The inertial mass can be altered, if desired, to tailor sensitivity for certain applications.

 

The output signal level is large and well filtered without giving up bandwidth. This is a basic feature resulting from the high capacitance of the sensing elements. The result is formidable dynamic range along with excellent noise immunity.

 

The high output level means that buffers and amplifier stages can often be eliminated. Since it is self powered, events can be recorded (launch impulse) by storing a charge on a capacitor before battery power becomes available and later interrogating to see if the proper impulse was obtained.
