Xa kuthelekiswa neegeji zetsimbi kunye ne-marble gauges, i-ceramic gauge inokuqina okuphezulu, ubunzima obuphezulu, ubuninzi obuphezulu, ukunyuka kwe-thermal ephantsi, kunye nokuphambuka okuncinci okubangelwa ubunzima babo, obunokumelana okugqwesileyo kokunxiba.Inobunzima obuphezulu kunye nokumelana okugqwesileyo kokunxiba.Ngenxa ye-coefficient encinci yokwandisa i-thermal, i-deformation ebangelwa ukutshintshwa kweqondo lokushisa incinci, kwaye ayichaphazeli lula indawo yokulinganisa.Uzinzo oluphezulu lolona khetho lungcono kwiigeyiji ezichanekileyo.
