Sensor/Transmitter/Transducer yeDzvinyiriro

Vazhinji vanogona kuvhiringidzika nezvekusiyana pakati pe, pressure sensor, pressure transducer uye pressure transmitter muzvikamu zvakasiyana. Mazwi matatu iwayo anogona kuchinjaniswa pasi pemamiriro ezvinhu akati. Pressure sensors nema transducers zvinogona kusiyaniswa kuburikidza ne output signal. Yekutanga inogona kutsanangurwa ne output signal ye4-20mA nepo yekupedzisira ne millivolt signal. Nemamwe mashoko, izwi rakakodzera rinogona kutsanangurwa zvichienderana ne output signal uye mashandisirwo.

Sensor yeKudzvanywa

Izwi rekuti Pressure sensor rinoreva marudzi ese ekumanikidzwa, mudziyo unoshandiswa kuyera kumanikidzwa. Kazhinji, chiratidzo chekubuda che millivolt chinochengetedza chiratidzo chakasimba pasina kurasikirwa kana mudziyo wakadaro wakaiswa 10-20 tsoka kubva pamagetsi. Chinopihwa ne5VDC chine chiratidzo chekubuda che 10mV/V chinoburitsa chiratidzo chekubuda che 0-50mV. Tekinoroji yekare inoburitsa 2-3mV/V (millivolts pavolt) chete ukuwo tekinoroji yepamusoro ichikwanisa kugadzira 20mV/V zvakavimbika. Zviratidzo zvekubuda zve millivolt zvinochengetedza nzvimbo dzemainjiniya dzekugadzirisa chiratidzo chekubuda zvichienderana nezvinodiwa zvesystem uye kuderedza saizi yepakeji pamwe nemutengo.

Muchina weKudzvanya

Kubuda kwepressure transducer ivoltage yepamusoro kana frequency signal inosanganisira 0.5 4.5 V ratiometric, 1 - 5 V uye 1 - 6 kHz. Output singal inoenderana nehuwandu hwemagetsi. Masignal evoltage output anokwanisa kupa kushandiswa kwakaderera kwemagetsi emagetsi emagetsi ari kure. Mavoltage emagetsi anotangira pa8-28 VDC anoda 5VDC regulated supply, kunze kwe 0.5 - 4.5V output. Dambudziko rakaoma remasignal evoltage output ekare riri mu "live zero", pane chiratidzo kana sensor iri pazero pressure. Sisitimu yekare inowanzo kundikana kuona musiyano uripo pakati pesensor yakakundikana isina output uye zero pressure.

Chinofambisa Kumanikidzwa

Chinotumira mweya chinoshanda kuburikidza nekuyera magetsi emudziyo kwete voltage. Chinhu chinonyanya kuoneka chiratidzo chekubuda kwemagetsi chiri 4-20mA.zvinotumira zvinodzvinyiriradzakagadzirirwa kutarisa kumanikidzwa kwemidziyo, mapaipi kana matangi panguva chaiyo. Matransmita ekumanikidza e4-20mA anopa kudzivirira ruzha rwemagetsi (EMI/RFI), uye achada simba re8-28VDC. Nekuti chiratidzo chiri kugadzira magetsi, chinogona kushandisa hupenyu hwebhatiri rakawanda kana chikashanda nekumanikidzwa kwakazara.
