Kuti ugadzire mhedzisiro yemhando yepamusoro, otomatiki maindasitiri maitiro anoda akawanda akasiyana zvikamu kuti zvishande zvisina mhosva pamwechete. Position sensors, ine mwero asi yakakosha chinhu muindasitiri otomatiki, ndiyo nyaya yechinyorwa ichi. Nzvimbo dzema sensors mukugadzira nekugadzirisa nzvimbo dzinoona kuti mabasa akakosha anoitwa sezvakarongwa, ayo anobatsira mukutarisa uye manejimendi ekugadzirwa kwemaitiro. kusavapo. Mavharuvhu epneumatic ane akasiyana mashandisiro nekuti anogona kufambisa masaini kune sisitimu achiiudza kuti iite chiitiko chakafanorongwa kana chinangwa chiri mukati mechinhambwe chakatemerwa chenzvimbo sensor.

Iyo chinzvimbo sensor inopa chiratidzo ichiudza sisitimu kuti imire kuita iyo pre-yakarongwa basa kana chinja kune rimwe basa kana chinangwa chasimuka kubva pane chinzvimbo sensor. Kunyangwe chinangwa chingave chiri chero chinhu, chinyorwa ichi chinongoongorora matangi esimbi uye "mainstream" nzira dzekuzviwana nekuda kwekureruka. Mechanical limit switch, inductive proximity sensors, chitubu chemuganho switch, uye muganho switch ndeimwe yeaya matekinoroji. Kunzwisisa mutauro wakajairwa unoshandiswa nevazhinji vevagadziri ve sensor kunobatsira usati waongorora akawanda marudzi enzvimbo sensors.

• Sensing range: kupatsanurwa pakati pechiso chekunzwa uye switch-activating target

• Hysteresis: chinhambwe chiri pakati penzvimbo yekuburitsa uye switch's actuation point

• Kudzokororwa: Kugona kwekuchinja kwehupenyu hwese kuti varambe vachiona chinangwa chimwe chete mukati mechikamu chimwe chete.

• Nguva yekupindura: nguva pakati pekutsvaga chinangwa uye kubuda kwechiratidzo chekugadzira.

muganhu chinja icho chiri mechanika

Electromechanical equipment inonzi mechanical limit switches inoshandisa yakananga kubata kumeso neinangwa kuti inzwe nzvimbo yechinangwa. Vanogona kutsigira mitoro yepamusoro uye kushanda pasina simba remagetsi. Mechanical switches haana hany'a nezve polarity kana voltage nekuti anoshandisa macontacts akaoma, zvichiita kuti asatadze kukanganiswa kwakasiyana kwemagetsi seruzha rwemagetsi, kukanganiswa kweredhiyo, kuvuza ikozvino, uye kudonha kwemagetsi. Ruoko rwerevhisi, bhatani, muviri, hwaro, musoro, zvinobatika, zviteshi, uye zvimwe zvinofamba zvekuchinja uku zvinowanzoda kugadziriswa. Votto mechanical limit switches inogona kunge isina kudzokororwa zvakanaka sezvo ivo vari mukubata chaiko kubata nevavariro. Iyo inonangwa pachayo pamwe neruwoko rwerevheti inogona kupfekwa kuburikidza nekubata kwenyama. Kune zvakare mazaru asina kudzivirirwa anogona kuita ngura, huruva, uye mwando. Nekuda kwedambudziko iri, nzvimbo dzakasimbiswa dzine njodzi uye dzakavharwa dzinowanzouya nemutengo wepamusoro.

Limit spring switch

Chitubu chemuganho switch ndeye electromechanical chishandiso chinoshandisa magineti kukwezva kuona nzvimbo yegineti chinangwa. Maviri madiki esimbi akavharirwa muchubhu yegirazi anowanikwa mukati mekuchinja. "Chinhu chetsanga" ndizvo izvi. Nekuda kwekunzwa kwayo kwemagineti, chinhu chetsanga chinopindura kune magineti zvinangwa nekuita. Sezvo ivo vasingade kutarisana zvakananga nechinangwa chekushanda, chitubu chemuganho switch chinopa ese mabhenefiti emuchina switch uchidzivirira kunetseka kwekupfeka.

Zvakajairwa ferrous tarisiro hazvigone kushandiswa nespring limit switch; magnetic targets anodiwa. Kuchinja kwetsanga hakuvimbike nekuti chinhu chetsanga, chubhu yegirazi, uye tumarata tudiki tunoneta nekukotama. Low contact pressure inogona kukonzera kutaura kwevanobatika uye zvisizvo zvikwangwani kubva patsanga munzvimbo dzakakwirira dzekudengenyeka.

Sensors for Inductive Proximity

A solid-state electronic device inonzi inductive proximity sensor inoshandisa shanduko mumunda wesimba rechinhu chesimbi kuona kuti chiri papi. Kubata kwenyama hakudiwe, uye hapana zvikamu zvinofamba zvejamu, kupera, kana kukuvadzwa, izvo zvinodzikisira kuchengetedza. Inoshingirirawo kuguruva netsvina nekuti haina mativi anofamba. Inductive proximity sensors inochinjika zvakanyanya kune akasiyana maapplication uye anowanikwa mune akati wandei saizi uye magadzirirwo. Inductive proximity sensors haigone kushivirira mitoro yakakwira ikozvino uye inoda kunze kwesimba sosi (magetsi) kuti ishande. Vanogona zvakare kuve panjodzi yekudonha kwemagetsi, kubuda kwemhepo, kukanganiswa kweredhiyo frequency, uye ruzha rwemagetsi. Kunyanya kupisa tembiricha uye kupinza hunyoro kunogona dzimwe nguva kuve kwakashata kune inductive proximity sensors.

muganhu chinja chinja

Uchishandisa yakakosha hybrid tekinoroji, muganho switch switch inogona kuwana ferrous zvinangwa kuburikidza nemagetsi magineti. Leverless muganho switch inovimbika zvinoshamisa mumamiriro ezvinhu akaoma uye kushandiswa kwenguva refu. Sezvo pasina kudikanwa kwekubata muviri kana simba rekunze, mitoro mikuru yazvino inogoneka uye hapana chinogona kumanikidza, kukotama, kupwanya, kana kugaya. Zvakafanana nekuchinja kwemuchina, haapindire kune ruzha rwemagetsi, kukanganiswa kweredhiyo, kubuda kwemhepo, uye kudonha kwemagetsi. Ivo zvakare havasi polarity- kana voltage-sensitive. Guruva, grime, kunyorova, kubata kwemuviri, uye ruzhinji rwezvinoodza kana makemikari hazvina mhedzisiro pamiganho yekuchinja. Iyo yakawanda yemhando ine yakakura yekushanda tembiricha renji uye yakachengeteka mukati. Iyo leverless limit switch yakanakira maapplication ayo anoda kusamira kwemvura uye kuputika proofing nekuda kwekuvharirwa kwayo kwakabatana uye yakasimba simbi yakavharirwa.

Position sensors yakakosha kune otomatiki yemaindasitiri maitiro. Kune akawanda ma sensor tekinoroji pamusika, imwe neimwe iine yakasarudzika seti yemaitiro ekuita. Kuti uwane kuita kwakakodzera uye kuvimbika, kutarisirwa kunofanirwa kuitwa kusarudza iyo chaiyo mhando ye sensor yekushandisa.
