System of notation

An universal abbreviation is used to notate generating modules: ТGM-N-C-h, where:
ТGM — product abbreviation — thermoelectric generating module;
N — number of thermocouples in the module;
С — length of the rib of the thermoelectric element basis (in millimeters);
h — height of the thermoelectric element (in millimeters)

For example, in the module TGM-127-1.0-2.5: 127 thermocouples (254 thermoelectric elements), every element has the cross-section of 1,0×1,0 mm and is 2,5 mm high.
