Maitiro ekugadzirisa zvikanganiso zve sensor yehuremu hwemahedhi akawanda

Munyori: Smartweigh– Huremu hwemisoro yakawanda

Chikamu chakakosha chemuchina wekuyera misoro yakawanda i sensor, iyo inowanzonzi load cell. Load cell chikamu chakakosha chemuchina wekuyera misoro yakawanda, uye basa rayo harisi pasi pe "moyo wemunhu", chinhu chakakosha pakutonga kana kuyera kwechigadzirwa kuchizadzisa mwero. Kana sensor yekuyera ikakundikana, zvichatiomera kufungidzira kuti ichaunza kurasikirwa kwakadii kumutsara wekugadzira. Naizvozvo, vashandisi vanofanirwa kugara vachiyedza chikamu ichi chakakosha. kuderedza kurasikirwa. Nhasi, Zhongshan Smart weight ichakutora kuti uone maitiro ekugadzirisa kukundikana kwe sensor yemuchina wekuyera misoro yakawanda. 1. Zero point output Tarisa zero point output, kureva, kukosha kwekubuda kwe sensor kana pasina mutoro, uye edza kubuda kwe sensor pasi pemamiriro ekuti mitoro yese (kusanganisira mitoro isingachinji senge zviyero nezvikamu zvinotumira simba) inofanira kubviswa.

Zero point ye sensor inofanira kuva kukosha kunowanikwa nekuyedza mumamiriro ezvinhu anodiwa nekugadzira, kuisa uye kushandisa sensor kudzivirira kukanganisa kunokonzerwa nehuremu hwe sensor pachayo. 2. Kuedza kudzivirira kuvharwa kwe insulation Kazhinji, tinoda kuyedza impedance iri pakati pe lead wire ye sensor ne sensor body (elastomer, shell, nezvimwewo). Cherechedza, bvisa sensor kubva pa junction box ne meter.

Bvisa dambudziko pabhokisi rekuyera insulation (mita), wobva wabatanidza mugumo mumwe wetambo yekuyedza kutambo yekuyedza (output, input, shielded wire, nezvimwewo), uye mumwe mugumo kune sensor body (elastomer, shell, nezvimwewo). Sezvinodiwa, iyi impedance≥5000MΩ. 3. Test bridge impedance Test bridge impedance ndeyekuyedza kuvimbika kwe sensor bridge. Pakuyedza, sensor inofanira kubviswa kubva pa junction box nezvimwe zvishandiso zvekuyedza.

Kuedza kwekupinda nekubuda kweimpedance ndekwekuyera kukosha kweimpedance painopinda uye painopinda yesensor pamwe chete nedigital multimeter test leads, uye kuenzanisa kukosha kwekuyedza nemutengo wechitupa chechigadzirwa; kusimbiswa kwebridge symmetry kunoreva kushandiswa kwedigital multimeter. Torai impedance pakati peinopinda neinopinda, uye muyere kuti muwane mapoka mana eimpedance values. Musensor ine symmetrically compensated, musiyano mukuru pakati pemapoka mana eimpedance values ​​​​haufanire kuva mukuru kupfuura 1Ω (kukosha kwemultimeter nekururama kwakaderera). Haufanire kuva mukuru kupfuura 2Ω). 4. Edzai sensor output. Batanidza sensor kune regulated power supply zvakasiyana, uye shandisa excitation voltage ye10~15VDC. Batanidza output end yesensor ku millivoltmeter (kana isa multimeter kuDC millivolt gear), isa mutoro painopinda yesensor zvichienderana nekuisa uye kushandiswa kwesensor, uye tarisa shanduko yeinopinda yesensor.
