Zvinokonzera Mhosho muTemperature Control Instruments ye Yekuedza Magetsi Furnace

(1) Zvinoenderana nehunhu curve yeyakaumbwa thermocouple, zvinogona kuoneka kuti thermoelectric kugona kwezvinhu zviviri zvakasiyana zvinoumba thermocouple haina mutsara nekupisa, uye mamwe ane macurvature akakura. Naizvozvo, kushandisa thermocouples kuyera tembiricha uye isiri-mutsara kururamisa kwakakosha zvakare. Kubata kusina kunaka kunounza kukanganisa.

(2) Iyo thermoelectric simba inogadzirwa neiyo thermocouple haina hukama chete nekupisa kwekuyeresa kumagumo, asiwo kune tembiricha yejoni inotonhora. Chete kana tembiricha yejoni inotonhora inogara iripo, iyo thermoelectric inogona kungoenderana nekupisa kwekupera kwekushanda. Zvishandiso zvizhinji zvine inotonhora-junction tembiricha muripo basa. Kana iyo ambient tembiricha yechiridzwa ikasachinja zvakanyanya, iko kukanganisa kunokonzerwa neinotonhora-junction tembiricha muripo inogona kuregererwa. Kubhadharwa zvakazara, ipapo imwe mhosho ichaunzwa zvakare. Kune iyo b-mhando thermocouple, sezvo iyo thermoelectric inogoneka isingasviki 3μv muhuwandu hwe0 ~ 50 ℃, muripo wetembiricha haudiwi.

1. Inogona kuonekwa kubva patafura ye index ye thermocouple kuti thermoelectromotive force output ne thermocouple iduku zvikuru. Kuti uwane kuyerwa kwakaringana, kuwedzera pakuvandudza iko kuyera kwechiridzwa, yekunze amplifier wedunhu inodiwa zvakare. , Izvi zvichaunzawo kukanganisa.
