Kub transmitter ceev faj
The power supply of the temperature transmitter must not have spikes, otherwise it may easily damage the transmitter. The calibration of the transmitter should be carried out after 5 minutes of power on, and attention should be paid to the ambient temperature at that time. When measuring high temperatures (>100 degree), sau cov ntaub ntawv yuav tsum tau siv los cais lub sensor kab noj hniav los ntawm lub hlws ris lub thawv los tiv thaiv lub transmitter los ntawm burnt tawm vim kub nyob rau hauv lub junction box. Thaum siv cov sensors nyob rau hauv cov xwm txheej loj cuam tshuam, lub casing yuav tsum ruaj khov kom tsis txhob muaj kev cuam tshuam, thiab cov khoom siv hluav taws xob thiab cov teeb liab yuav tsum yog Ф 10 shielded cable kis tau tus mob, cov txiv ntseej crimping yuav tsum tau nruj kom airtightness. Tsuas yog RWB qhov kub thiab txias transmitter muaj qhov tso zis ntawm 0-10mA, uas yog peb lub xaim hluav taws xob thiab qis dua 5 feem pua ntawm cov nqi ntau. Vim lub off yam ntxwv ntawm lub transistor, nws tsis yog linear. Qhov ntsuas kub ntawm qhov ntsuas kub yuav tsum tau ntsuas txhua 6 lub hlis. Yog tias DWB tsis tuaj yeem kho cov kab hluav taws xob vim muaj kev txwv hauv Circuit Court, nws yog qhov zoo tshaj plaws los xaiv qhov ntau raws li cov lus qhia los xyuas kom meej nws cov linearity.
Yog vim li cas rau cov ntaub ntawv tsis raug tso tawm
1. Ntev Circuit Court ntev thiab teeb liab attenuation;
2. Kab impedance tsis sib haum;
3. Lub teeb liab cuam tshuam thiab tsis muaj kev tiv thaiv;
