Abstract
A load sensing gasket having a gasket body defining a service opening for fluids and having a load sensor encased in a cavity in the body. The gasket body comprises a first gasket layer providing a first outer gasketing surface and a first inner surface, a second gasket layer providing a second outer gasketing surface and a second inner surface, the inner surfaces together defining the cavity and side walls for defining a perimeter for the cavity. The load sensor includes confronting electrodes and a pressure sensitive electrically resistive material between the electrodes and conductors extending outwardly of the perimeter. A seal between the first and second gasket layers around the load sensor seals the electrodes in the cavity from fluids when the gasket is in use.
