WP421A Chopatsira Kupanikizika Kwapakati ndi Kutentha Kwambiri
Chotumizira cha WP421 cha kutentha kwapakati ndi kwapamwamba chimagwiritsidwa ntchito kwambiri poyesa ndi kuwongolera mafakitale osiyanasiyana, kuphatikiza kuyeza kwa hydraulic ndi level, Boiler, Kuwunika kuthamanga kwa thanki ya gasi, Kuyesa ndi kuwongolera mafakitale, Mafuta, Makampani a mankhwala, gombe lakunja, mphamvu zamagetsi, nyanja, mgodi wa malasha ndi Mafuta ndi Gasi.
Chotumizira cha WP421A chapakati ndi chapamwamba kwambiri chimasonkhanitsidwa ndi zinthu zomwe zimakhudzidwa ndi kutentha kwambiri zomwe zimalowa kunja, ndipo sensor probe imatha kugwira ntchito mokhazikika kwa nthawi yayitali kutentha kwambiri kwa 350℃. Njira yolumikizira yozizira ya laser imagwiritsidwa ntchito pakati pa pakati ndi chipolopolo cha chitsulo chosapanga dzimbiri kuti chisungunuke kwathunthu kukhala thupi limodzi, kuonetsetsa kuti transmitter ili yotetezeka pansi pa kutentha kwambiri. Pakati pa kuthamanga kwa sensor ndi amplifier circuit zimatetezedwa ndi ma gasket a PTFE, ndipo chotenthetsera chimawonjezedwa. Mabowo amkati a lead amadzazidwa ndi aluminiyamu silicate, yomwe imaletsa kutentha kuti kuyendetsedwe bwino ndikuwonetsetsa kuti gawo la amplification ndi conversion circuit likugwira ntchito pa kutentha kovomerezeka.
Mtundu wowonetsera:
1. Kuwonetsedwa kwa LCD: 3 1/2 bits; 4 bits; 4 bits/5 bits smart display
2: Chiwonetsero cha LED: 3 1/2 bits; 4 bits
Zotulutsa zosiyanasiyana za chizindikiro
Ndondomeko ya HART ikupezeka
Ndi chitoliro choziziritsira / chotenthetsera
Kulondola kwambiri 0.1% FS, 0.2% FS, 0.5% FS
Kapangidwe ka nyumba kakang'ono komanso kolimba
Kutentha kogwira ntchito: 150℃, 250℃, 350℃
Mita ya mzere 100%, LCD kapena LED imatha kusinthidwa
