Abstract: A sensor head component is configured for use with a monitoring tool assembly in the performance of one or functions as part of a monitoring process. The sensor head component is configured to include at least one electrical component for performing the function as well as a memory device upon which operational information for the component is storable. The sensor head component is further configured to include an elongated body within which the electrical component is positionable and a base portion connectable to the elongated housing which further provides for mechanical and electrical engagement in a port for the tool assembly through application of a linear force.

Abstract: A sensor head apparatus is configured to include a plurality of sensor ports each configured to receive and electrically interconnect with a sensor head component. The sensor head is further configured to be connectable to a housing for a multi-parameter monitoring tool assembly, wherein electrical connections are provided between the electronics for the tool assembly and any sensor head component engaged in the sensor head. Each port in the sensor head is configured to receive and engage a sensor head component through application of a linear force on the component.

Abstract: A multi-parameter tool assembly provides for monitoring of one or more parameters, such as those relating to water quality. As part of the tool assembly, a sensor head is configured to receive and electrically interconnected with a plurality of interchangeable sensor head components. The sensor head components are specially configured to provide for the removal and insertion out of sensors through the application of a linear force. The housing for the tool assembly, which may include a plurality of layers, is further configured for simplified assembly with the sensor head and other components through the use of at least one radially compressive sealing device. The assembly is further connectable to a communications network wherein signals may be exchanged with one or more remote locations.
