Abstract

A monitor (10) includes a transducer (20) registered with a pump (22) for generating electrical signals reflecting the status of the pump (22). The output of the transducer (20) is conditioned by a pump monitor circuit (16) to indicate the status (18) of the pump (22) and for subsequent delivery to an alarm processing unit (C) and alarm condition (D). The monitor (10) reports both normal and abnormal pump (22) conditions.
