Cabbirka heerkulku waa mid ka mid ah arrimaha ugu muhiimsan ee saameeya saxnaanta mitirka kulaylka ee ultrasonic-ka. Iyadoo dareemaha socodka uu go'aaminayo mugga biyaha ka gudbaya dhuumaha, dareemayaasha heerkulku waxay cabbiraan heerkulka biyaha ee la keenayo iyo kuwa la soo celinayo. Mitirka kuleylku wuxuu markaa isku daraa qiimayaashan si loo xisaabiyo isticmaalka tamarta kulaylka.
Tiknoolajiyada kala duwan ee dareemaha heerkulka ee la heli karo, PT100 iyo PT1000 Resistance Temperature Detectors (RTDs) waa labada ugu badan ee loo isticmaalo nidaamyada kuleylinta iyo qaboojinta. Inkasta oo labaduba ay yihiin dareemayaal heerkul iska caabin ah oo platinum ah oo leh xasillooni iyo saxnaan aad u fiican, haddana waxay ku kala duwan yihiin qiimaha iska caabinta, astaamaha fiilooyinka, xasaasiyadda calaamadaha, iyo ku habboonaanta codsiga.
Fahmidda kala duwanaanshahan waxay ka caawisaa injineerada, qandaraaslayaasha, iyo naqshadeeyayaasha nidaamka inay doortaan dareemaha ugu habboon mashruucyadooda cabbiraadda kulaylka.
Waa maxay dareemayaasha PT100 iyo PT1000?
PT100 iyo PT1000 labaduba waa qalabka lagu ogaado heerkulka iska caabbinta platinum (RTDs) oo la soo saaray iyadoo la raacayo heerarka IEC 60751.
"PT" waxay u taagan tahay platinum, halka lambarku uu matalayo iska caabbinta magaca dareemaha ee 0°C.
* PT100: 100 Ω marka heerkulku yahay 0°C
* PT1000: 1000 Ω heerkul ah 0°C
Marka heerkulku kordho, iska caabbinta korontada ee labada dareemayaal waxay ku kortaa si la saadaalin karo oo ku dhow toosan. Cabbiraha kulaylku wuxuu cabbiraa iska caabbintan wuxuuna u beddelaa qiime heerkul sax ah.
Maadaama platinum-ku uu yahay mid kiimiko ahaan deggan oo aad loogu celcelin karo, dareemayaasha RTD waxaa si weyn loogu isticmaalaa kuleylinta degmada, HVAC, xakamaynta habka warshadaha, iyo nidaamyada maaraynta tamarta.
Maxay Dareemayaasha Heerkulka Muhiim ugu yihiin Mitirka Kulaylka?
Mitirka kulaylka ee ultrasonic-ka ayaa xisaabiya tamarta kulaylka isagoo isticmaalaya saddex cabbir oo muhiim ah:
* Heerka socodka biyaha
* Heerkulka biyaha sii
* Heerkulka biyaha ku celi
Farqiga heerkulka (ΔT) ee u dhexeeya khadadka sahayda iyo soo celinta ayaa si toos ah u saameeya isticmaalka tamarta ee la xisaabiyay.
Xitaa qalad yar oo cabbirka heerkulka ah ayaa horseedi kara khaladaad la dareemi karo oo ku yimaada biilasha waqti ka dib.
Sababtan awgeed, labada dareemayaal heerkulka ah ee lagu bixiyo mitirka kulaylka badanaa waa kuwo warshadda isku mid ah oo loo habeeyey sidii lammaane. Beddelidda hal dareemayaal oo keliya ama isku darka dareemayaal aan la barbar dhigi karin waxay yareyn kartaa saxnaanta cabbirka waana in guud ahaan laga fogaadaa.
PT100 iyo PT1000: Waa maxay faraqa?
In kasta oo labada dareemayaalba ay ku shaqeeyaan mabda' isku mid ah, haddana astaamahooda koronto way kala duwan yihiin.
1. Qiimaha iska caabbinta
Farqiga ugu cad waa iska caabinta saldhigga.
Nooca iska caabbinta dareemaha ee 0°C
PT100 100 Ω
PT1000 1000 Ω
Maadaama PT1000 uu leeyahay toban jibaar iska caabinta PT100, waxay abuurtaa isbeddel weyn oo ku yimaada danabka oo ku yimaada isbeddelka heerkulka isku midka ah, taasoo sahlaysa wareegyada elektaroonigga ah inay ogaadaan isbeddellada heerkulka yar yar.
2. Xasaasiyadda Calaamadaha
Dareemayaasha PT1000 waxay soo saaraan calaamad koronto oo xooggan sababtoo ah iska caabintooda sare.
Tani waxay bixisaa dhowr faa'iido:
- Xal ka wanaagsan
- Difaaca buuqa oo la hagaajiyay
- Xasillooni cabbir sare leh
- Habaynta calaamadaha oo fudud
Mitirka kulaylka dijitaalka ah ee casriga ah oo leh elektaroonik isku dhafan, PT1000 badanaa waxay bixisaa waxqabad lagu kalsoonaan karo.
3. Saamaynta Iska caabinta Siligga Rasaasta
Iska caabbinta fiilada ayaa saameysa saxnaanta RTD.
Iyada oo la adeegsanayo dareemayaasha PT100, xitaa xaddi yar oo iska caabin fiilooyin ah ayaa keeni kara khaladaad heerkul la cabbiri karo, gaar ahaan marka fiilooyinka dhaadheer la isticmaalo.
Tusaale ahaan:
1 Ω oo ah iska caabbinta fiilada waxay u taagan tahay qiyaastii 1% iska caabbinta magacaaban ee dareemaha PT100.
Isla 1 Ω waxay u taagan tahay oo keliya qiyaastii 0.1% oo ka mid ah iska caabbinta magacaaban ee dareemaha PT1000.
Natiijo ahaan, dareemayaasha PT1000 aad bay uga yar yihiin iska caabbinta fiilooyinka rasaasta waxaana badanaa la door bidaa rakibaadda halkaas oo xisaabiyuhu ku yaal meel fog oo ka fog dareemayaasha heerkulka.
4. Qaabeynta Fiilooyinka
Dareemayaasha RTD waxaa badanaa laga heli karaa:
- 2-fiilo
- 3-fiilo
- Qaabeynta 4-silig
Dareemayaasha PT100 waxay inta badan isticmaalaan fiilooyin 3-fiilo ah ama 4-fiilo ah si ay u magdhabaan iska caabbinta fiilada.
Dareemayaasha PT1000 badanaa waxay gaaraan saxnaan ku filan iyadoo la adeegsanayo habeyn fudud oo laba-xarig ah sababtoo ah saameynta iska caabbinta fiilada ayaa aad uga yar.
Tani waxay yarayn kartaa dhibka rakibidda iyo kharashyada guud ee fiilooyinka.
5. Saxnaanta Cabbirka
Labada dareemayaal ee PT100 iyo PT1000 labaduba waxay gaari karaan saxnaan aad u fiican marka si habboon loo hagaajiyo.
Codsiyada cabbiraadda kulaylka ee wax ku oolka ah, saxnaanta cabbirka guud waxay ku xiran tahay wax badan:
- Iswaafajinta dareemaha
- Tayada hagaajinta
- Habka rakibidda
- Taabashada kulaylka
- Qalabka elektarooniga ah ee mitirka kulaylka
marka loo eego doorashada u dhaxaysa PT100 iyo PT1000.
Nidaamka PT100 ee si fiican loo qaabeeyey wuxuu noqon karaa mid sax ah sida nidaamka PT1000.
6. Tixgelinta Rakibaadda
Iyadoo aan loo eegin nooca dareemaha, rakibid habboon ayaa lagama maarmaan ah.
Dareemayaasha heerkulka waa inay had iyo jeer:
- Lagu rakibay tuubooyinka sahayda iyo soo celinta saxda ah.
- Si buuxda ugu geli godka kuleylka ama jeebka lagu shubo.
- La xiriir kuleyl wanaagsan dareeraha habka.
- Ka ilaali dhaawaca farsamada.
- Ka fogow fidinta fiilooyinka aan loo baahnayn haddii uusan soo-saaruhu oggolaan.
Rakibaadda aan habboonayn waxay inta badan keentaa khaladaad cabbir oo ka weyn nooca dareemaha laftiisa.
