There is disclosed instrumentation for use in connection with one or more tablet presses of various types, and in particular rotary tablet presses, for virtually any reasonable combination and number of such tablet presses. Tablet formation information, in particular compression and ejection force information, tablet capping information and force information related to the time of occurrence of punch withdrawal is provided and processed by such instrumentation. This information is selectively applied to converting means which renders the selected information in a convenient data form for processing. Selection of the information may be made for example based on the need or desire to monitor a particular tablet press, tablet press station and/or individual tablet die/punch set combination. The selected information is processed by data processing means to provide output signals, including tablet press control signals, relating for example to the average and standard deviation of a pre-established number of consecutive tabletting events and determination of the frequency and number of abnormal tablet formations. The instrumentation may be employed to determine tabletting characteristics of pharmaceutical tablet granulations. Provision is also made for determining and isolating tablets failing to meet pre-established criteria.
