  • Data logging device with separated data memory unit having internal power source and transducer interface unit for connection to external transducers
    Patent number: 4817049
    Abstract: A data logging device has a data memory unit (11) and a transducer interface unit (1). The data memory unit has an internal power source (12), an integrated circuit memory component (23) for storing data under the control of a microprocessor (18) in the memory unit, light emitting diodes (14, 21) for indicating the amount of data stored in the memory component and the power source state. A connector component (19) connects the memory component to receive data from the transducer interface unit. The transducer interface unit (1) has a plurality of ports (2) for connection of remote transducers and an analog to digital converter (5) for translating signals received from the ports into data signals which can be transferred to the memory component in the data memory unit through a connector component (9) connected to the connector component (19) of the data memory unit.
