Abstract
A snap-in LVDT force sensor includes a housing having separate chambers for enclosing an LVDT and an assembly of circuit components. One end of the housing is coupled for movement with one link of a two-link frame which is subject to the forces to be measured. A plunger is coupled for movement with the other link and includes a shaft which extends into one of the chambers to support an LVDT core for reciprocal movement within the LVDT coil assembly. A bellows is sealingly and flexibly coupled between the plunger and housing to provide protection from the environment. An optional spring may provide additional stiffness between the plunger and housing.
