Category:Electrochemical integrators

English: An electrochemical integrator is a miniature electrochemical reactor (electrochemical cell), usually employing Ag-Cl electrolyte. When an external electric current is forced through the two electrodes of such cells, it transfers elementary silver from one electrode to another. Normally, voltage drop between two electrodes is very low. At a certain predefined value of time-current integral the reaction expends all active electrolyte, and the voltage between two electrodes jumps to more than one Volt. When the external circuit senses this shift, fuze is fired, kaboom. First documented use of the device was in the inertial navigation system of the V-2 missile prototypes (but apparently not the production V-2s).
