Peb hom hluav taws xob tso zis ntawm lub siab Sensor
Jul 17, 2024
Lub siab sensors feem ntau muaj nrog peb hom hluav taws xob tso zis; millivolt, volt thiab 4-20mA.
Millivolt tso zis siab Sensors
Sensors nrog millivolt tso zis feem ntau yog qhov kev lag luam siab tshaj plaws. Cov zis ntawm millivolt sensor yog nominally nyob ib ncig ntawm 30mV. Qhov tseeb tso zis yog ncaj qha proportional rau lub siab sensor input zog los yog excitation. Yog hais tias qhov excitation fluctuates, cov zis yuav hloov. Vim tias qhov kev vam khom rau qib excitation, tswj cov khoom siv hluav taws xob tau pom zoo siv nrog millivolt sensors. Vim tias cov teeb liab tso zis tsawg heev, lub sensor yuav tsum tsis txhob nyob hauv ib puag ncig hluav taws xob tsis zoo. Qhov kev ncua deb ntawm lub sensor thiab cov cuab yeej nyeem ntawv yuav tsum tau khaws cia luv luv.
Voltage Output Siab Sensors
Voltage output sensors muaj xws li ib qho teeb liab txias txias uas muab cov zis ntau dua li millivolt sensor. Cov zis feem ntau yog 0-5Vdc lossis 0-10Vdc. Txawm hais tias tus qauv tshwj xeeb, qhov tso zis ntawm lub sensor tsis yog ib txwm ua haujlwm ncaj qha ntawm excitation. Qhov no txhais tau hais tias cov khoom siv hluav taws xob tsis muaj kev tswj hwm feem ntau txaus yog tias lawv poob rau hauv ib lub zog uas tau teev tseg. Vim tias lawv muaj cov zis ntau dua cov sensors no tsis cuam tshuam rau hluav taws xob suab nrov li millivolt sensors thiab tuaj yeem siv rau hauv ntau qhov chaw lag luam.
4-20 mA Tso zis siab Transmitters
Txij li thaum lub teeb liab 4-20mA muaj kev cuam tshuam tsawg tshaj plaws los ntawm cov suab nrov hluav taws xob thiab kev tiv thaiv nyob rau hauv cov teeb liab xov hlau, cov transmitters yog qhov zoo tshaj plaws siv thaum lub teeb liab yuav tsum tau xa mus ntev. Nws tsis yog qhov tsis yooj yim uas siv cov transmitters hauv cov ntawv thov uas cov hlau lead yuav tsum yog 1000 ko taw lossis ntau dua.
