Kusintha kwa Smart Communication pa Transmitters

Zida zamafakitale zapita patsogolo kwambiri pazaka makumi angapo zapitazi, pomwe zida zambiri zidangokhala zosavuta 4-20 kapena 0-20mA kutulutsa kwa analogi molingana ndi kusinthaku. Kusintha kwa ndondomekoyi kunasinthidwa kukhala chizindikiro chodzipatulira cha analogi choperekedwa kuchokera ku chida chodutsa pa 2-waya kupita ku chizindikiro kapena dongosolo lolamulira, ndi makonzedwe a madontho ambiri, omwe amafunikira kupeza mwachindunji kwa kusintha kwamanja ndi ogwira ntchito yosamalira.

Ubwino womwe ungakhalepo waukadaulo wa digito mu zida zadziwika pambuyo pake. Pakhoza kukhala zambiri zamtengo wapatali ndi ntchito zomwe zili mu chida, monga kusintha kwa chipangizo, malire a alamu, nthawi yogwiritsira ntchito & zikhalidwe, chidziwitso cha matenda, ndi zina zotero. Kupeza deta yotereyi kumathandiza kukhathamiritsa ntchito ya chipangizocho, ndipo pamapeto pake kumapangitsa kuti ntchitoyo igwire bwino.Pulogalamu ya HARTidatuluka ngati imodzi mwa njira zoyambira zopezera chidziwitso chosowa ichi kuti zida zikhale zanzeru.

Ukadaulo wa HART umalola kulumikizana ndi chida cha analogi pogwiritsa ntchito chizindikiro cholumikizirana cha digito chomwe chimatumizidwa pawaya wa 2 womwewo monga kutulutsa kwa analogi. Chizindikiro cha digitochi chinapereka mauthenga a 2-njira pakati pa chida ndi wolandira popanda kusokoneza zotulukapo, kuthandizira kupeza zidutswa zosiyanasiyana za deta. Ndi HART, ogwira ntchito amatha kulumikizana ndi cholumikizira ndikuchita masinthidwe kapena kuzindikira pomwe akuyesa muyeso wanthawi yeniyeni.

WangYuan WP421A High Temperature Pressure Transmitter Ndi 4 ~ 20mA + HART Protocol Output

Panthawi imodzimodziyo, chitukuko cha matekinoloje ena a digito chinali kukuchitikanso chomwe chidzafalitsidwe pamisewu yayikulu yolankhulirana, yomwe ili ndi phindu linalake, kuphatikizapo luso lamakono la Fieldbus.Protocol ya Modbus yokhala ndi mawonekedwe a RS-485. Modbus ndi serial master-slave open protocol, yomwe imalola wopanga aliyense kuti aphatikize protocol mu chida, kuti apereke mwayi wamba ku zida zanzeru kuchokera kumakina olandila.

WangYuan WP401A Pressure Transmitter Ndi RS485 Modbus Output & Ex-proof

Chifukwa cha kupita patsogolo kwaukadaulo pazaka makumi asanu zapitazi, kutumiza zida kwasintha kuchokera pakusintha koyambira kupita ku chidziwitso chochuluka chomwe chikupezeka mpaka kumakampani. M'tsogolomu, ukadaulo wa digito upitilizabe kupereka zambiri kuchokera kwa ma transmitter, ndi njira zambiri zofikira.

Ku WangYuan, wopanga waku China yemwe ali ndi zaka zopitilira 20 pantchito yoyimbira zida, timayika patsogolo kugwiritsa ntchito zotulutsa zanzeru zopangira zida zoyezera. Zambiri mwazinthu zathu zoyezera kupanikizika, mulingo, kutentha ndi kuyenda zimavomereza makonda pazotulutsa zazizindikiro kuphatikiza HART Protocol yolembetsedwa ndi RS-485 Modbus kuti ikwaniritse zofuna za ogwiritsa ntchito ndi momwe akumunda.
