Abstract
An axial force measurement apparatus (40) comprises a head member (42) adapted for receiving force imparted by an external force-applying source, and a transducer (44) such as a load cell for measuring the amount of force applied to the head member (42). Electronic circuitry (61) for receiving, processing, storing and/or sending electrical information generated by the transducer is provided either externally to the measurement apparatus (40), or is integrated with the apparatus (40). The apparatus (40) can be used to calibrate the valve crimping station (75) and/or the test firing station (125) of a metered dose delivery canister production line. The apparatus (40) is designed to emulate an actual canister (12).
