Special Features:

Model 7257at is a small hermetically sealed piezoelectric accelerometer with integral electronics, designed specifically for measuring vibration on flight test vehicles. This tranducer offers the functions of a flight test accelerometer and an airborne charge. Designed for flight test. 360 degree cable orientation, ground isolated.

Properties:

An item specifically designed to transmit supersonic frequency wave motion energy to another item under test, and to receive components of reflected energy, the characteristics of which when interpreted on an associated indicator, provides facilities for the determination of flaws or other irregularities of the item under test. Does not include the indicator. See also transducer, motional pickup and detector, metal flaw, electronic.
