Duk da haka, hanyoyin gano lanƙwasa na gargajiya suna fama da matsaloli kamar ƙarancin inganci da rashin daidaito. Sabanin haka, na'urori masu auna sigina na LVDT (Linear Variable Variable Differential Transformer), tare da fa'idodinsu na babban daidaito, babban aminci, da aunawa mara gogayya (misali: LVDTs suna amfani da na'urar bincike don taɓa saman abu, suna haifar da matsi na tsakiya don cimma ma'aunin rashin gogayya da babban daidaito), yanzu ana amfani da su sosai a cikin gano lanƙwasa na abu na zamani.
Ka'idar Aiki:
Ma'aunin Babu Takaici:Yawanci babu hulɗa ta zahiri tsakanin tsakiyar da ke motsi da tsarin na'urar, ma'ana LVDT na'urar ce mara gogayya. Wannan yana ba da damar amfani da shi a cikin ma'auni masu mahimmanci waɗanda ba za su iya jure wa lodin gogayya ba.
Rayuwar Inji mara iyaka: Domin kuwa yawanci babu wata hulɗa tsakanin tsarin LVDT na tsakiya da na'urar coil, babu wani sashi da zai iya gogawa ko ya lalace, wanda hakan ke ba wa LVDTs damar rayuwa ta injiniya mara iyaka. Wannan yana da mahimmanci musamman a aikace-aikacen da ake da aminci sosai.

Maimaita Maki Mara Kyau:Wurin da aka sanya maɓallin null na LVDT a ciki yana da matuƙar karko kuma ana iya maimaita shi, koda a cikin kewayon zafin aiki mai faɗi. Wannan yana sa LVDTs su yi aiki da kyau a matsayin na'urori masu auna matsayi mara kyau a cikin tsarin sarrafa madauri mai rufewa.
Kin Amincewa da Giciye-Axis:LVDTs suna da matuƙar saurin kamuwa da motsin tsakiya na axial kuma ba sa jin daɗin motsi na radial. Wannan yana ba da damar amfani da LVDTs don auna tsakiya waɗanda ba sa motsi a cikin madaidaiciyar layi.
Amsar Saurin Saurin Sauƙi:Rashin gogayya yayin aiki na yau da kullun yana ba da damar LVDT ya mayar da martani da sauri ga canje-canje a matsayin tsakiya. Amsar mai ƙarfi ta firikwensin LVDT kanta tana iyakance ne kawai ta hanyar tasirin inertial na ƙaramin nauyin tsakiya.
Cikakken Fitarwa:Fitowar LVDT siginar analog ce da ke da alaƙa kai tsaye da matsayi. Idan aka samu katsewar wutar lantarki, ana iya ci gaba da aunawa ba tare da sake daidaita ta ba (ana buƙatar a kunna wutar don samun ƙimar canja wurin wutar lantarki bayan katsewar wutar lantarki).
