Abstract
An integrated cell and the test station is disclosed in a unitary package which includes internally encapsulated wiring connections at both the cell and test station. The cell and test station are tethered together by a flexible bungee tube which can be coiled and which can elongate or contract. The flexible tube provides a variable length and wide lateral flexibility. The tube also provides a convenient means to encapsulate the connections at both the cell and test station. The cell has a unique core formed by a double junction ceramic capsule. A pure copper coil element is positioned in the capsule in a super saturated solution of copper sulphate, for example. The capsule is sealed and the coil or element is electrically connected to a lead extending through the tube, and the end of the tube is encapsulated sealing the connection. The capsule is joined to one end of the bungee tube and the entire end is embedded in a stabilized hygroscopic gel which contains additional salt crystals. The entire cell end of the tube is contained in a microporous filter bag, which is in turn secured to the lower end of the tube. The test station comprises a section of rigid plastic tube with a slightly domed cap. Brass rivets are recessed in the top of the dome and connected to appropriate wiring inside the dome. The interior of the test station is then encapsulated fully sealing the wiring connections, and connecting the rigid tube to the bungee tube.
