Molao-motheo oa ts'ebeliso ea sensor ea khatello

1. Mefuta e sa tšoaneng

Ho na le mefuta e mengata ea li-sensor tsa mochini tse kang resistance strain gauge pressure sensor, semiconductor strain gauge pressure sensor, piezoresistive pressure sensor, inductive pressure sensor, capacitive pressure sensor, resonant pressure sensor le capacitive acceleration sensor. Empa e sebelisoang ka ho fetisisa ke mochine oa khatello ea piezoresistive, o nang le theko e tlaase haholo, ho nepahala ho phahameng le litšobotsi tse ntle tsa linear.

2. Kutloisiso

Ka sensor ea khatello ea khatello ea maikutlo, re qala ho utloisisa tekanyo ea khatello ea methapo ea methapo. The resistance gauge ke sesebelisoa se nang le kutlo se fetolang phetoho ea khatello karolong e lekantsoeng hore e be lets'oao la motlakase. Ke e 'ngoe ea likarolo tsa mantlha tsa sensor ea khatello ea piezoresistive. Litekanyo tse sebelisoang ka ho fetesisa tsa ho hanyetsa ke litekanyo tsa khatello ea tšepe le li-semiconductor strain gauge. Ho na le mefuta e 'meli ea litekanyo tsa tšepe tse hanyetsanang le tšepe: sekala sa terata le sekala sa tšepe. Hangata, sekala sa khatello se tlamahane ka thata ho matrix a mechanical strain ke moemeli ea khethehileng oa ho kopanya. Ha khatello ea kelello ea matrix e fetoha, tekanyo ea khatello ea ho hanyetsa e boetse e senyeha, e le hore boleng ba ho hanyetsa ha tekanyo ea khatello bo fetohe, 'me motlakase o sebelisoang ho hanyetsa o fetoha. Boleng ba ho hanyetsa ba gauge ena ea khatello hangata bo nyane ha bo hatelloa, 'me sekhahla sena sa khatello ka kakaretso se entsoe ka borokho ba A strain,' me se holisoa ke amplifier ea sesebelisoa se latelang, ebe se fetisetsoa potolohong ea ts'ebetso (hangata phetoho ea A / D le CPU) pontšo kapa mochine oa tsamaiso.
