The shidma heerka biyaha: soocidda, shaqo, sharaxaad ka mid ah qalabka

Supply of heerka biyaha waxaa loo isticmaalaa in la xaddido heerka dareeraha ee taangiyada kala duwan. qalabka loo adeegsado xakamaynta daad, xakamaynta biyaha kor loogu qaadayo biyo-xireenno iyo berkadood, guriga, waxay waxaa loo isticmaalaa in lagu dhaqo, ururka ka ah nidaamyada biyaha iyo nidaamka diirinta, iyo wixii la mid ah. d.

Qoondaynta iyo description

qalabka ku xiran tahay habka cabbirka loo qaybin karaa xiriir iyo non-xiriir. shidma Heerka biyaha nooca ugu horeysay si toos ah ku taal derbiga taangiga, waxay badalato xiriirada la joogo gaaro heerka dareeraha kuwaas oo waxaa la dhigayaa. Intaa waxaa dheer, cabbirka heerka biyaha la fulin karo by hababka soo socda :. Capacitive, magnetic, indhaha, ultrasonic, iwm shidma The indhaha heerka biyaha ayaa no qaybo guuraya, waxaa la dhajinta on derbiga taangiga iyo waxa korkiisa oo gaarey heer Fundka kiciyay. rays indhaha kala go'do keena isbedel signal on saarka ee qalabka a.

shidma Heerka biyaha (birtiina), waa qalab sax universal for tiro balaadhan oo ah codsiyada kala duwan ee u baahan cabbirka socodka dareeraha aad u sax ah. aaladaha noocan oo kale ah waa heer multi-hal iyo, iyo sidoo kale toosan (oo analog).

Dhawaanshaha shidma heerka biyaha shaqeyn karto cabitaanno kala duwan, adkaha ah iyo qalabka la kala duwan ah sumoobo iyo ku nafwaayay. aaladaha noocan oo kale ah kala qaybsan yihiin qalabka capacitive iyo ultrasonic.

qalabka Contact (Level) waa xiriir la dareeraha, waxay qiyaasay. Waxay la Hawiyaha laga yaabaa in biyaha (sida radar ama hydrostatic) ama gundhig derbiga taangiga at height jirin kalimo (fargeeto indhaha qalabka vibratory). Waxay yihiin indhaha, piezoelectric fargeeto, radar ama radar, hydrostatic iyo fiber optic.

Sida loo sameeyo shidma heerka biyaha ee taangiga?

Haddii aadan ku qanacsanayn waxyaabaha la iibiyaa dukaamada, isku day in aad qalab noocan oo kale ah on iyaga u gaar ah, gaar ahaan sababtoo ah waa mid fudud ilaa xad. Shidma, soo jeediyay in aad fiiro, waxaa loo isticmaalaa in la xaddido heerka dareeraha ah xilal kala duwan. By qalab this signal la sameeyo on ama off of bamka biyaha ama signal. Qalabka wuxuu u yahay kordhiyo DC fudud, taas oo la aasaasay on labada transistors. Trimmer kuu ogolaanayaa inaad si loo soo dajiyo dareenka lagama maarmaanka ah ee qalabka. Transistors waxaa ilaaliya diode Semiconductor. qalab wuxuu bixiyaa tilmaan ku LED hal amro on ururiyaha ee transistor ugu horeysay. Si aad u soo shirin waxaan u baahan nahay resistors (220 kOhm, 10 kOhm -. 3 cutub, 1.2 ohms), Mid ka mid ah capacitor (470 ee Ismaamulka / 50 V), laba transistors (VS547), diode (1N4001) iyo mid ka mid LED. Nidaamka noocan oo kale ah waxaa ku shaqeeya by danab si toos ah 6-15V iyo gubtay, koronto ee 75 MA.

shidma waxaa loo isticmaali karaa sida waslad khafiifa oo bireed Maro adag (10 x 50 mm). Waa in ay lagu wadaa inay 3 mm uurkooda bireed.

gunaanad

Gebogebadii, Omet, in qalabka sida waa mid aad u faa'iido leh, gaar ahaan ganacsiga gaarka loo leeyahay. Xukun naftaada: shidma this lagu rakibi karo ee taangiga for qubeyska ama qubeyska, marka waraabiyo beerta ururka, sidoo kale nidaamka kaydinta biyaha ee gurigaaga.
