摘要
A differential variable reluctance transducer (DVRT) is provided to measure a translation parameter, such as acceleration and/or deceleration of a test projectile. The DVRT, contained in a canister of the projectile, includes a cylindrical housing and an electronics module. The housing defines a cavity containing insulation and a bobbin around which a wire coil is wrapped. The housing has an attachment end and a distal end that faces the acceleration indicator. The bobbin is disposed substantially collinear to the housing. The wire coil is helically disposed around the bobbin. The insulation fills the remainder of the cavity. The electronics module receives electric current from the wire coil and connects to a data recorder.
