Indlela yokuqoqa izinga lokushisa le imishini yokuqeda imvamisa ephezulu

Imishini yokucisha imvamisa ephezulu ishisisa ama-workpiece amancane, ukusuka kumazinga okushisa asekamelweni kuya ku-900° ukushisisa kwe-high-frequency, ngokuvamile ngaphansi kwamasekhondi ayi-10, futhi isikhathi sifushane kakhulu. Ngakho-ke, isivinini sokuphendula senzwa siphezulu kakhulu, futhi isikhathi sokuphendula kufanele silawulwe ngaphakathi kwe-200 ms, ngaphandle kwalokho iphutha liyoba likhulu kakhulu. Njengoba i-thermal conductivity yenzwa yokuxhumana ihamba kancane futhi ine-hysteresis esobala, ayifaneleki ukusetshenziswa. Uma kucatshangelwa ukusebenza kwezindleko zamathemometha okushisa e-infrared nefiber optical angathinteki, ekugcineni kwakhethwa ithemometha ye-infrared ye-infrared CTLT20 yaseJalimane, ububanzi bayo: -40 ℃ ～900 ℃, isikhathi sokuphendula: 150 ms, iphutha 1% Ngaphakathi kwalokhu, ithemometha inezinga eliphezulu lokulinganisa izinga lokushisa. kunxeshezelwe ngokomugqa, futhi umugqa muhle, ongabona kangcono ukuqoqwa kwezinga lokushisa.

Ukukhishwa kwethemometha ye-infrared yinani le-analog elingu-0～10 V noma 4～20 mA. Okokuqala, setha ubudlelwano obuhambisanayo phakathi kobuningi be-analog kanye nenani ledijithali, okungukuthi, inani elincane le-analog quantity lihambisana nenani eliphansi lebanga lokulinganisa izinga lokushisa le-thermometer. Inani eliphakeme kakhulu lihambisana nenani eliphakeme lebanga lokulinganisa izinga lokushisa le-thermometer; bese imojula ye-A/D ye-PLC isetshenziselwa ukuqoqa izinga lokushisa ukuze kutholwe inani lokushisa lobuningi bedijithali; ekugcineni, yahlulela ukuthi inani lokushisa elibekiwe lifinyelelwa kuhlelo lwe-PLC, futhi wenze isenzo esihambisanayo Ngesikhathi esifanayo, inani lokushisa elihambisanayo nolwazi lwesenzo luboniswa esikrinini sokubonisa ngesikhathi sangempela.
