I-4 ngocingo lwe-PT100 RTD i-Temperature Sensors

4 ngocingo PT100 RTD Izibonisi zoBubushushu boMfanekiso oboniswayo

Inkcazelo emfutshane:

Le yinzwa ye-4-wire PT100 yeqondo lokushisa kunye nexabiso lokumelana ne-100 ohms kwi-0 ° C. IPlatinam inomlinganiselo wobushushu ochasayo wokumelana kunye nexabiso lokumelana linyuka ngobushushu, 0.3851 ohms/1 ° C, yenziwe ngokuhambelana nemigangatho yezizwe ngezizwe ye-IEC751, iplagi kunye nokudlala lula.

I-4 ngocingo lwe-PT100 RTD i-Temperature Sensors

Ukudityaniswa kwezikhokelo ezimbini ekupheleni kwengcambu ye-platinum resistor yaziwa ngokuba yinkqubo ye-wire-wire, apho ezimbini zesikhokelo zibonelela ngokuqhubekayo kwi-resistor platinum! , eguqula i-R ibe ngumqondiso we-voltage u-U, kwaye emva koko ikhokelela u-U kwisixhobo sesibini ngokusebenzisa ezinye iindlela ezimbini.

Ngenxa yokuba umqondiso we-voltage ukhokelwa ngokuthe ngqo ukusuka kwindawo yokuqala yokumelana neplatinam, kunokubonwa ukuba le ndlela inokuphelisa ngokupheleleyo umphumo wokuchasana kwezikhokelo, kwaye isetyenziselwa ukukhangela ukushisa okuphezulu.

Yintoni umahluko phakathi kwenkqubo yocingo olumbini, ucingo oluthathu kunye nolune?

Iindlela ezininzi zokudibanisa zineempawu zazo, ukusetyenziswa kwenkqubo ye-wire-wire iyona elula, kodwa ukuchaneka kokulinganisa kuphantsi. Inkqubo yocingo oluthathu lunokuphelisa ngcono impembelelo yokumelana nokukhokela kwaye isetyenziswa kakhulu kwishishini. Inkqubo ye-wire-wire inokuphelisa ngokupheleleyo impembelelo yokumelana ne-lead, esetyenziswa kakhulu kwi-high-precision measurement.
