Pressure transmitters zvinhu zvakakosha mumaindasitiri maapplication anoyera asiri emagetsi emuviri, senge tembiricha, kudzvanywa, kumhanya, uye kona. Kazhinji, 4-20mA transmitters anouya mumhando nhatu: ina-waya transmitters (waya mbiri dzemagetsi emagetsi uye maviri azvino kubuda waya), matatu-waya transmitters (yazvino kubuda uye magetsi anogovera waya imwe), uye maviri-waya transmitters.
Muchinyorwa chino, tichakurukura zvakanakira maviri-waya pressure transmitters, rudzi rwekumanikidza transmitter iyo yakawana mukurumbira mumakore achangopfuura. Heano mamwe eakakosha mabhenefiti maviri-waya pressure transmitters:
1. Kusanyanya kubatwa neparasitic thermocouples uye madonhwe emagetsi: Mapiritsi maviri-waya pressure transmitters haanyanyi kubatwa neparasitic thermocouples uye voltage inodonha pamwe newaya, izvo zvinovabvumira kushandisa dzakatetepa, isingadhure waya. Izvi zvinogona kuchengetedza huwandu hwakakosha hwetambo uye mari yekuisa.
2. Yakadzikiswa kukanganiswa kwemagetsi: Kana kupikisa kwekubuda kwenzvimbo iripo kwakakura zvakakwana, magetsi akakonzerwa nemagnetic field coupling muwaya loop kazhinji haakoshi. Izvi zvinodaro nekuti iyo yekukanganisa sosi inokonzeresa diki ikozvino inogona kudzikiswa uchishandisa dzakamonyoroka-matambo tambo.
3. Kureba kwetambo refu: Capacitive kupindira kunogona kukonzera kukanganisa mukupikisa kweanogamuchira. Nekudaro, kune 4-20mA maviri-waya loop, kuramba kweanogamuchira kazhinji 250Ω, iyo idiki zvakakwana kuburitsa zvikanganiso zvisina basa. Izvi zvinobvumira kureba uye kureba kwetambo kureba zvichienzaniswa nevoltage telemetry system.
4. Kuchinja-chinja mukusarudza kwechiteshi: Zvakasiyana-siyana-zvinoratidza-imwe kana zvigadziriso zvekurekodha zvinogona kuchinjwa pakati pematanho akasiyana ane hurefu hwakasiyana hwetambo pasina kukonzera misiyano yechokwadi. Izvi zvinobvumira kutorwa kwedata kwakadzika uye nepakati pekutonga.
5. Yakanakira kukanganisa kukanganisa: Kushandisa 4mA yezero-level inoita kuti zvive nyore kuona mapeji akazaruka, mafupi mafupi, kana kukanganisa sensor (0mA mamiriro).
6. Zviri nyore kuwedzera michina yekudzivirira yekuvhiya: Zvishandiso zvekudzivirira zvekuwedzera zvinogona kuwedzerwa nyore nyore kune maviri-waya yekubuda port, zvichiita kuti ive yakachengeteka uye inopesana nemheni uye masurges.
Mukupedzisa, maviri-waya pressure transmitters anopa akati wandei mabhenefiti pamusoro pemamwe marudzi ekutapurirana, senge kuderedzwa kukonzeresa kune parasitic thermocouples uye madonhwe emagetsi, kuderedzwa kwemagetsi kupindira, kureba kwetambo, kuchinjika mukusarudza chiteshi, kuona kukanganisa kuri nyore, uye kuwedzera nyore kwekuvhiya. midziyo yekudzivirira. Nemabhenefiti aya, maviri-waya pressure transmitters arikunyanya kufarirwa mumaindasitiri maapplication ayo anoda kwakaringana uye akavimbika kuyerwa kwekumanikidza.
