Qhov zoo ntawm HART raws tu qauv

HART (Highway Addressable Remote Transducer) raws tu qauv tuaj yeem hais txog cov chaw taws teeb sensor high-speed channel qhib kev sib txuas lus raws tu qauv.

Nws yog ib qho kev hloov pauv zaus (FSK) thev naus laus zis raws li Tswb 202 tus qauv kev sib txuas lus, uas paub txog kev sib txuas lus digital los ntawm superimposing lub teeb liab zaus ntawm 4-20mA tam sim no. Muaj 2 zaus sib txawv: 1200 Hz thiab 2200H: sawv cev "0" thiab "1", superimposed ntawm 4-20mA DC teeb liab nyob rau hauv daim ntawv ntawm sine yoj, txij li qhov nruab nrab tus nqi ntawm cov sine waves yog xoom, tsis muaj DC tivthaiv raug tsim. Nws yuav tsis cuam tshuam rau 4 ~ 20rnA cov txheej txheem teeb liab, thiab nws ua tiav cov kev sib txuas lus tiag tiag tsis cuam tshuam cov teeb liab kis.

Cov yam ntxwv ntawm HART raws tu qauv yog tias nws tuaj yeem paub txog kev sib txuas lus ntawm cov teeb liab digital ntawm cov kab hluav taws xob sib txuas uas twb muaj lawm, thiab tuaj yeem muab cov kev pheej hmoo tsis muaj kev daws teeb meem rau kev txhim kho kev sib txuas lus ntawm cov cuab yeej, thiab muaj kev sib tw ua lag luam muaj zog hauv lub sijhawm hloov pauv los ntawm analog. qhov system rau digital system.

Peb UTOP muaj cov cuab yeej nrog HART raws tu qauv zoo liULB-Itheem transmitter,UTI 5kub transmitter thiabUIB 1siab transmitter rau koj xaiv.
