Inzwa ye-Excavator Psresses iyinzwa esetshenziswa kabanzi kunazo zonke, iyigama elijwayelekile lokuthola igesi, uketshezi, oluqinile nezinye izinto phakathi kwamandla anamandla angenamandla, futhi kubandakanya
Ama-Manometers alinganisa ingcindezi yomoya engenhla kanye nama-gaeum gauges alinganisa ingcindezi yomoya ngezansi. Kunezinhlobo eziningi zezinzwa ze-Force Sensor, indlela yendabuko yokulinganisa ukufaka izimo zenkolo kanye nokusuka ezintweni eziningi ukukhombisa ukugcinwa kwenjini yokujova kagesi, kepha ivolumu yayo inkulu, i-clumsy, futhi okuphumayo akuyona i-non-linear. Ngokukhula kwamakhono ama-microelectorics, ukusetshenziswa kwezinto ze-semiconductor Peiezoresureve umphumela wezinzwa eziphakeme, ukuthuthukiswa kwe-semiconduort force sensors, ama-silicon piezoresive kanye ne-capacitive, anosayizi omncane, asetshenziswa kakhulu ezinzwaneni ze-semiconductor force sensor. Lapho i-semiconductor icindezelwe phezulu ku-crystal, ukumelana kwaso kuyoshintsha. Ubudlelwano phakathi koshintsho lwe-conductive yokumelana nokucindezelwa lubizwa ngokuthi i-semiconductor piezoresurive effect, futhi inzwa ye-mechage eyenziwe yalo mphumela ibizwa nge-piezoresistive force struge ebizwa nge-semizenduorer gauge ebhekwe endaweni ye-econistic, ebizwa ngokuthi yi-paiezoresistive sensor. Okunye ukumelana nokungamelana nobuchwepheshe obenziwe ngobuchwepheshe bokuhlanganisa obuhlangene kwi-substrate yezinto ezisetshenziswayo ze-semiconductor, ukuze i-silicon warstrate yakha inzwa yonke efanayo, ebizwa ngokuthi inzwa ephelele ye-piezoresistive. Inezimpawu zokuzwela okuphezulu, ukunemba okuphezulu, ubukhulu obuncane, isisindo esikhanyayo, imvamisa ephezulu yokusebenza, isakhiwo esilula, umsebenzi othembekile kanye nempilo ethembekile.
