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 kunoenderana ne voltage yepamusoro kana frequency signal inosanganisira 0.5 4.5 V ratiometric, 1 - 5 V uye 1 - 6 kHz. Output singal inoenderana ne supply kazhinji. Voltage output signals dzinokwanisa kupa kushandiswa kwakaderera kwe current kune zvishandiso zvinoshandisa remote batter. Supply voltages dzinotangira pa 8-28 VDC dzinoda 5VDC regulated supply, kunze kwe output ye 0.5 - 4.5V. Dambudziko rakaoma re voltage output signals dzekare riri mu "live zero", pane signal kana sensor iri pa zero pressure. Sisitimu yekare inowanzo kundikana kuona musiyano uripo pakati pe sensor yakundikana 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.
