DPharp – eto seriya vysokotochnyh intellektualnyh preobrazovateley davleniya.
Preobrazovateli (datchiki) davleniya seriyasi EJA va EJX sovremennyx intellektual datchiklarning barcha funktsiyalarini o'rnatadi. Otlichitelnoy osobennostyu preobrazovateley seriy EJA va EJX yavlyaetsya printsipi izmereniya davlat: v kachestve chuvstvitelnogo elementa v nix ispolzuetsya kremnievyy mexanicheskiy rezonator – unikalnaya razrabotka firmy Iokogava .
Chto takoe kremnievyy rezonator?
Kremnievyy rezonator predstavlyaet soboy paralelepiped ploskoy formasi, zashchishchennyy germetichnoy kapsuloy va integratsiyalashgan ploskost kremnievoy membrany. Pri izgotovleni chuvstvitelnyh elementov primenyyutsya samye sovremennye texnologi rosta kristallov, blagodarya chemu vsya eta slojnaya struktura poluchaet s edinoy monokristallicheskoy reshetkoy.
Prinsip raboty kremniego rezonatora: V zavismosti ot znaka prilojennogo davleniya rezonator rastyagivaetsya yoki sjimaetsya, v natijada chego chastoyta ego sobstvennyx mexanicheskix kolebaniy sootvetstvenno rastet yoki umenshaetsya. Kolebaniya mexanicheskogo rezonatora v postoyannom magnitnom pole preobrazuyutsya v kolebaniya elektricheskogo kontur, i, v itoge, na vyhode chuvstvitelnogo elementa poluchaet tsifrovoy (chastotnyy) signal, tochno otrajayushchiy velichin davlen izmeryaem.
l ineyka datchikov davleniya i perepada davleniya - seriya EJX v svoey osnove ispolzuyut tot je, chto i v preobrazovatelyax Yokogawa EJA , "chastotno-rezonansnyy" printsipi preobrazovaniya davleniya v chastotnyy signal na baze kremnievogo kristalla ( DPHarp texnologiyasi).
Pri etom v serii EJX sushchestvenno izmenena konstruksiya kapsuli, blagodarya chemu znachitelno umensheno vremya otklika (teper uni sostavlaet 95 msek - EJX - samyy bystryy intellektual datchik!!!). Krome togo pererabotana elektronika (teper o'ziga to'liq zaxiraviy zahiraga daje standartnix bazovyx ispolneniy), dobavleny funksiyalari, uluchshena tochnost. Vsya lineyka EJX standartno sertifikatirovana po TUV navoven bezopasnosti SIL2
