Yadda za a zabi firikwensin matsa lamba

Wani nau'in matsi da kuke aunawa shine farkon na'urar firikwensin matsa lamba.Matsakaicin firikwensin ya kasu kashi na inji da matsa lamba (na'ura mai aiki da karfin ruwa), inji matsa lamba naúrar yawanci N, KN, KGf, matsa lamba na'ura mai aiki da karfin ruwa naúrar ne yawanci KPa, MPa, PSI, da dai sauransu.
Bari muyi magana game da zabin matsa lamba na inji.
1) Game da matsa lamba na inji: abu na farko da za a yi la'akari shine auna matsa lamba ko tashin hankali, idan akwai kawai don auna matsa lamba, zaɓi firikwensin matsa lamba, idan kuna buƙatar auna tashin hankali, kuna buƙatar zaɓar firikwensin tashin hankali.
Bugu da ƙari, idan kuna buƙatar haɗa kayan aiki ko mai sakawa, yana da kyau a zabi firikwensin matsa lamba don sauƙaƙe kayan aikin kayan aiki.Idan abokin ciniki ya zaɓi firikwensin matsa lamba, firikwensin matsa lamba don danna ƙasa, fara danna kayan aiki, sannan ci gaba da danna ƙasa, har sai samfurin.Ta wannan hanyar, ana tilasta firikwensin matsa lamba, sannan samfurin shine ƙarfi, Na'urori masu auna firikwensin da samfuran suna ƙarƙashin ƙarfi daban-daban, samfurin da kansa yana ƙarƙashin ƙasa da ƙarfi fiye da na'urar firikwensin, Lokacin da tsarin ya yi, abokin ciniki. zai iya ƙara ƙimar diyya kawai a cikin shirin PLC.Ana iya guje wa wannan yanayin gaba ɗaya idan an zaɓi nau'in firikwensin latsa kuma an haɗa firikwensin da kayan aiki tare.

2) zaɓin kewayon ma'auni, don guje wa lalacewa ga firikwensin saboda nauyin nauyi, a cikin kewayon daidaiton da aka ba da izini, ya kamata ya zama babba gwargwadon yiwuwa.Idan ana amfani da Silinda ko Silinda na lantarki, yakamata a ƙididdige matsakaicin matsawar silinda ko silinda na lantarki, gami da ƙarfin tasiri.

3) zaɓi na girman girman firikwensin matsa lamba, kamar babu iyaka ga wurin shigarwa, zaku iya zaɓar girman girman firikwensin ɗan ƙaramin girma, manyan firikwensin gabaɗaya suna da ramukan threaded a ƙasa, sauƙin shigarwa, kai tsaye. gyarawa tare da sukurori, na iya ceton matsalar sarrafa kayan aiki.Bugu da kari, gabaɗaya girman babban firikwensin ya fi daidai.

4) Yanayin zafin jiki yana da wani tasiri akan aikin firikwensin, zaɓin na'urar firikwensin ya kamata kuma yayi la'akari da yanayin zafin jiki, kamar yanayin yanayi ya yi yawa, ya kamata a bayyana shi ga masu sana'a, zaɓin babban firikwensin zafin jiki.

5), Saboda matsi na firikwensin fitarwa shine siginar millivolt, siginar ba siginar siginar analog ba ne, yakamata a samar da mai watsawa, wanda ake kira amplifier, siginar cikin siginar siginar analog ko siginar dijital, kamar daidaitaccen analog 4- 20mA, 0-5V, 0-10V, dijital RS232, RS485, da dai sauransu.

6) Idan buƙatar nunawa akan shafin, ya zama dole don dacewa da kayan aikin nuni, kayan aikin nuni da watsa zaɓuɓɓuka biyu.Don PLC ko wani tsarin saye, ya kamata a zaɓi kayan aikin nuni tare da fitowar analog ko sadarwar serial.
