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.
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.
Indicates there is no data in the hmirs and the nsn is in a fsc not generally suspected of containing hazardous materials.
Item does not contain precious metal.
No known electrostatic discharge (esd) or electromagnetic interference (emi) sensitivity.
Represents items with no adp components
The item does not have a nuclear hardened feature or any other critical feature such as tolerance, fit restriction or application.
HMIC: Hazardous Material Indicator Code. A one position code that identifies a hazardous item.
PMIC: Precious Metal Indicator Code. A one position code which identifies items that have precious metals as part of their content. precious metals are those metals generally considered to be uncommon, highly valuable, and relatively superior in certain properties such as resistance to corrosion and electrical conductivity.
ESD: Electrostatic Discharge. Indicates if an item is susceptible to electrostatic discharge or electromagnetic interference damage. electrostatic discharge damage occurs when an accumulation of static electricity generated by the relative motion or separation of materials is released to another item by direct contact. electromagnetic interference damage occurs when an item comes into proximity with an electrostatic or magnetic field.
ENAC: Enviromental Attribute Code. Identifies items with environmentally preferred characteristics.
CRITL: Criticality Indicator Code. Indicates an item is technically critical by tolerance, fit, application, nuclear hardness properties, or other characteristics.
