Dzvinyiriro sensor 89448-34020202020

1. Remote kutaurirana

Zvazvino (4 kusvika ku20 ma) ndiyo yaunofarira analog interface paunenge uchiendesa ruzivo pamusoro penzvimbo refu. Izvi zvinokonzerwa nekubuda kweVoltage kunonyanya kukanganiswa mukukanganisa kurira, uye chiratidzo pachayo chinosimbiswa nekutambisa cable. Nekudaro, iko kubuda kwazvino kunogona kumira kure kure kure uye kunopa zvakakwana uye zvakaringana kudzvanywa kuverenga kubva kuTransmitter kune data data yekuwana data.

2. Robustness kune rf kupindira

Tambo tambo dzinotambudza kune electromagnetic (EMI) / radio frequency (RFI) / Electrostatic (esd) Kupindira kubva pamatambo akaipisisa nemitsetse. Ruzha urwu rwemagetsi ruchikonzera kukuvara kwakanyanya kune zvakakura zvisina kufanira chiratidzo senge masaini vemagetsi. Dambudziko iri rinogona kukurirwa nyore nekushandisa zvakaderera zvisina kufanira uye masaini epamberi mazvina, akadai se4-20 ma.

3, kugadzirisa dambudziko

Iyo 4-20 ma signal ine 4 ma yekubuda uye iyo yekumanikidza kukosha ndeye zero. Izvi zvinonyatso kureva kuti chiratidzo chine "live zero", saka kunyangwe kuverenga kwekumanikidzwa kwezero, kuchapedza 4 ma yeazvino. Kana chiratidzo chesangano Izvi hazvigone kuwanikwa mune nyaya yemasaini yeVoltage, iyo inowanzobva kubva ku0-5 v kana 0-10 v, uko 0 v uye 0 v Kubuda kwegumi kunoratidza zero kumanikidza zero.

4. Signal yekuzviparadzanisa

Iyo 4-20 ma yekubuda chiratidzo chakasarudzika chiratidzo chazvino chiratidzo, uye nekuvapo pamigumo miviri (kutapurirana uye kugamuchira) kunogona kutungamira chiuno, zvichikonzera kusagadzikana chiratidzo. Kuti udzivise izvi, mumwe nemumwe maawa 4-20 ma sensor mutsara unofanirwa kuve wakasarudzika. Nekudaro, kana zvichienzaniswa ne 0-10 v kubuda, izvi zvinodzivirira sensor kubva pakuva daisy-zvakasungwa kune imwe chete tambo infrarture.

5. Kugamuchira kurongeka

Paunenge uchiendesa kubva pakumanikidza sensor, iyo voltmeter inogona kududzira zviri nyore nyore iyo 0-10 v chiratidzo pamugumo. YEMAHARA 4-20 Ma Output, chiratidzo chinogona kungoverenga mushure mekunge mugamuchire anoshandurwa kuva voltage. Kuti ushandure ichi chiratidzo muLopage kudonha, kupesana kwakabatana mune zvakatevedzana pamatare ekunze. Iko kurongeka kweanopikisa uku kwakakosha kwazvo pakureverera kweiyo chiratidzo chekugamuchira.
