ABSTRACT:
A device for measuring the distance moved by an applicator head of a container filling and capping station and, hence, a force applied by the head, the device having a housing, a plunger telescopically inter-fitted with the housing so as to be substantially linearly movable relative thereto, a biasing device biasing the members to a rest position, and an indicator mounted on the members; the indicator having at least one component thereof movable such that, during one stage of relative movement of the members from their rest position against the bias of the biasing device and return to their rest position under such bias, the at least one component is fixed relative to one of the members and movable relative to the other member, and such that during the other stage of that movement the at least one component is fixed relative to the other of the members and movable relative to the one member to thereby provide a measure of the relative movement of the members in one of the stages, and wherein the external form of the measuring device corresponds to a standard container to which a closure member is to be fitted by an applicator head of a container filling and capping machine, such that the measuring device can be inserted upstream from the applicator head in a process line for containers passed through the machine and thereby subjected to the action of the applicator head to obtain a read-out of distance moved or pressure applied by the applicator head.
