Saiki, ora akeh instrumen ngawasi resistensi dinamis sing diwasa diwasa kanggomesin las titik frekuensi medium, kanthi paling akeh eksperimen lan pangembangan. Sensor ing sistem kontrol biasane nggunakake Kripik efek Hall utawa sensor kumparan sabuk alus kanggo ngumpulake voltase antarane elektroda lan saiki welding. Informasi iki banjur diproses lan dikontrol nggunakake unit pangolahan mikrokomputer lan sirkuit thyristor. Senajan sirkuit ngarep-mburi bisa beda-beda, prinsip padha.
Sirkuit sistem pemantauan resistensi dinamis kalebu saluran saiki, saluran voltase, lan saluran konduktansi. Saluran saiki kalebu terminal input sensor saiki, amplifier, lan arus sing dibenerake gelombang lengkap. Saluran voltase kasusun saka kabel transmisi voltase, amplifier watesan, amplifier nilai absolut, lan arus rectified gelombang lengkap sing tepat. Saluran konduktansi kasusun saka pembagi lan gerbang kontrol.
Pembagi ngitung konduktansi, nyedhiyakake konduktansi sing sebanding karo sinyal input. Gerbang kontrol (VF) dikontrol dening pulsa sing diasilake dening sirkuit diferensial (Z). Kanthi saben puncak ing Z saben setengah siklus, pulsa sempit digawe lan dikirim menyang VF, mbukak gerbang. Setelan VF ngisolasi pengaruh voltase induksi périodik amarga owah-owahan saiki kanthi cepet. Saluran konduktansi ngirim sinyal menyang CPU, ing ngendi petungan ditindakake lan printah kontrol ditanggepi. Miturut data, sistem pemantauan resistensi kasebut bisa ngontrol ing kisaran ± 4% saka kurva resistensi sing wis ditemtokake.
Bagean pemantauan resistensi dinamis saka monitor tingkat resistensi kalebu sensor saiki, sirkuit transmisi voltase (kalebu sirkuit penghapusan voltase induksi), unit kalkulasi resistansi, unit inspeksi owah-owahan resistensi, komparator, lan unit semi-kontrol. Pitungan resistance dileksanakake saben setengah siklus, nanging output punika nilai resistance rata-rata saben siklus. Bagean voltase kudu kalebu sirkuit kanggo ngilangi gangguan voltase kanggo entuk penurunan voltase sing bener ing elektroda.
