Pulagi yowonera mafuta imatanthawuza sensa yamphamvu yamafuta. Mfundo yake ndi yakuti injini ikathamanga, chipangizo choyezera kupanikizika chimazindikira kuthamanga kwa mafuta, kutembenuza chizindikiro chamagetsi kukhala chizindikiro chamagetsi, ndikuchitumiza ku dera lopangira ma signal. Pambuyo pakukulitsa mphamvu yamagetsi ndi kukulitsa kwapano, chizindikiro chowonjezera champhamvu chimalumikizidwa ndi choyezera kuthamanga kwamafuta kudzera pamzere wa siginecha.
Kuthamanga kwa mafuta a injini kumasonyezedwa ndi chiŵerengero chamakono pakati pa ma coil awiri mu chizindikiro cha kusinthasintha kwa mafuta. Pambuyo pa kukulitsa kwamagetsi ndi kukulitsa kwamakono, chizindikiro cha kuthamanga chikufanizidwa ndi mphamvu ya alamu yomwe imayikidwa mu dera la alamu. Pamene magetsi a alamu ali otsika kuposa mphamvu ya alamu, dera la alamu limatulutsa chizindikiro cha alamu ndikuyatsa nyali ya alamu kupyolera mu mzere wa alamu.
Sensor pressure yamafuta ndi chida chofunikira pozindikira kuthamanga kwamafuta a injini yamagalimoto. Miyezo imathandizira kuyendetsa bwino ntchito ya injini.
Pulagi yowonera mafuta imapangidwa ndi chip sensor chokhuthala cha filimu, makina opangira ma siginecha, nyumba, chipangizo chokhazikika cha board ndi mayendedwe awiri (mzere wama sign ndi alamu). Dongosolo lopangira ma siginecha lili ndi gawo loperekera mphamvu, sensa yolipira chiwongola dzanja, zerosetting circuit, voltage amplifying circuit, a amplifying circuit, a flter circuit and alarm circuit.
