Kuti pave nemhedzisiro yepamusoro-soro, kugadzira otomatiki mashandiro emaindasitiri kunoda zvikamu zvakasiyana-siyana kuti zvishande pamwe chete zvisina matambudziko. Maposition sensors, chinhu chidiki asi chakakosha mukugadzirwa kwemaindasitiri, ndicho chiri kutaurwa munyaya ino. Maposition sensors munzvimbo dzekugadzira nekugadzira anovimbisa kuti mabasa akakosha aitwa sezvakarongwa, izvo zvinobatsira mukutarisa nekutarisira maitiro ekugadzira. Kuti zvive pachena, basa ravo guru nderekutsvaga "zvinangwa" kana kufambisa zvinhu uye kutaura nezvekuvapo kana kusavapo kwazvo. Mavharuvhu epneumatic ane mashandisirwo akasiyana-siyana nekuti anogona kutumira zviratidzo kuhurongwa achiudza kuti uite chiito chakarongwa kana chinangwa chiri mukati medaro rakatarwa kubva kuposition sensor.

Sensor yenzvimbo inopa chiratidzo ichiudza sisitimu kuti irege kuita basa rayo rakagadzirwa kare kana kuti ichinje kune rimwe basa kana chinangwa chikafamba kubva pane sensor yenzvimbo. Kunyangwe chinangwa chingave chero chinhu, chinyorwa chino chichangoongorora zvibodzwa zvesimbi uye nzira "dzakakosha" dzekuzviwana kuitira kuti zvive nyore. Maswichi emuganho wemechanical, ma sensor ekuva pedyo, maswichi emuganho wespring, uye maswichi emuganho ndedzimwe dzematekinoroji aya. Kunzwisisa mutauro wakajairika unoshandiswa nevakawanda vevagadziri vemasensa kunobatsira usati waongorora mhando dzakasiyana dzema sensor enzvimbo.

• Rudzi rwekunzwa: kupatsanurwa pakati pechiso chekunzwa nechinobatidza switch

• Hysteresis: daro riri pakati penzvimbo yekuburitsa simba nenzvimbo yekushandura simba

• Kudzokororwa: Kugona kwekuchinja kwehupenyu hwese kweswitch kugona kuziva chinangwa chimwe chete mukati mechikamu chimwe chete.

• Nguva yekupindura: nguva iri pakati pekuona chinangwa uye kugadzirwa kwechiratidzo chinobuda.

switch yemuganho inoshanda nekanika

Midziyo yemagetsi inonzi mechanical limit switches inoshandisa kubatana zvakananga nechinhu chinonangwa kuti inzwe nzvimbo yechinhu chinonangwa. Inogona kutsigira mitoro yemagetsi yakakwira uye inoshanda isina simba. Machinicha emagetsi haana hanya ne polarity kana voltage nekuti anoshandisa ma contacts akaoma, zvichiita kuti asakanganiswa nemagetsi akasiyana-siyana akadai seruzha rwemagetsi, kupindirana kwema frequency eredhiyo, leakage current, uye voltage drop. Ruoko rwe lever, bhatani, muviri, hwaro, musoro, ma contacts, ma terminals, nezvimwe zvinhu zvinofamba zvema switch aya zvinowanzoda kugadziriswa. Votto mechanical limit switches inogona kunge isina kudzokororwa zvakanaka sezvo iri pakubata zvakananga nechinonangwa. Chinangwa pachacho pamwe neruoko rwe lever zvinogona kupera simba kuburikidza nekubata panyama. Kunewo maburi asina kudzivirirwa anogona kubatwa nengura, guruva, uye hunyoro. Nekuda kwedambudziko iri, nzvimbo dzine njodzi dzakasimbiswa uye ma contacts akavharwa anowanzo kuve nemutengo wakakwira.

Chinja chemuchina wekupisa chine muganho

Chishandiso chemuganho wechitubu chishandiso chemagetsi chinoshandisa kukwezvana kwemagineti kuti chione nzvimbo yechinangwa chemagnetic. Matinji maviri madiki esimbi akavharirwa muchubhu yegirazi ari mukati mechitubu. Chinhu che "reed element" ndicho ichi. Nekuda kwekunzwa kwayo kwemagineti, chinhu chemuganho chinopindura kune zvinangwa zvemagnetic nekuita kuti chishande. Sezvo zvisingade kubatana zvakananga nechinhu chacho kuti chishande, maswiti emuganho wechitubu anopa mabhenefiti ese ekuchinja kwemechanical uku uchidzivirira kusakara.

Zvinangwa zvesimbi hazvigone kushandiswa ne switch dze spring limit; ma magnetic targets anodiwa. Reed switch haivimbike nekuti reed element, girazi chubhu, uye simbi diki zvinoneta nekukotama. Kumanikidzwa kwakaderera kunogona kukonzera kurira kwe contacts uye zviratidzo zvisirizvo kubva ku reed mumamiriro ezvinhu ekuzunguzika kwakanyanya.

MaSensor eInductive Proximity

Mudziyo wemagetsi unonzi inductive proximity sensor unoshandisa shanduko mumunda wesimba rechinhu chesimbi kuti uone kuti chiri kupi. Kubatwa kwemuviri hakudiwi, uye hapana zvikamu zvinofamba zvekuti zvikanganise, zvisakare, kana kukuvara, izvo zvinoderedza kugadziriswa. Hazvinawo simba guruva netsvina nekuti hazvina zvikamu zvinofamba. Inductive proximity sensors dzinokwanisa kushandiswa zvakasiyana-siyana uye dzinowanikwa muhukuru hwakasiyana-siyana uye magadzirirwo akasiyana-siyana. Inductive proximity sensors haigoni kutsungirira mitoro yemagetsi yakakwira uye inoda simba rekunze (magetsi) kuti rishande. Dzinogonawo kunge dziri panjodzi yekudonha kwemagetsi, kuyerera kwemvura, kupindirana kwemafrequency eredhiyo, uye ruzha rwemagetsi. Kuchinja-chinja kwekushisa kwakanyanya uye kupinda kwehunyoro dzimwe nguva zvinogona kuipa kune inductive proximity sensors.

chinja chemuganhu wemuganhu

Uchishandisa tekinoroji yakasarudzika yehybrid, maswichi emiganhu yemuganho anogona kuwana zvinangwa zveferrous kuburikidza neminda yemagetsi. Maswichi emiganhu asina kubatwa akavimbika zvikuru mumamiriro ezvinhu akaoma uye kushandiswa kwenguva refu. Sezvo pasina chikonzero chekubata kwemuviri kana simba rekunze, mutoro mukuru wemagetsi unogoneka uye hapana chinogona kudzvanya, kupeta, kupwanya, kana kukuya. Kufanana nemaswichi emakanika, haapindi ruzha rwemagetsi, kupindirana kwemafrequency eredhiyo, kudonha kwemhepo inobuda, uye kudonha kwemagetsi. Haapindiwo polarity- kana voltage. Guruva, tsvina, hunyoro, kubata kwemuviri, uye huwandu hwakawanda hwezvinhu zvinoparadza kana makemikari hazvina simba paswichi dzemiganhu yemuganho. Ruzhinji rwemhando idzi dzine tembiricha yakakura yekushanda uye dzakachengeteka mukati madzo. Swichi yemiganhu isina kubatwa yakanakira mashandisirwo anoda kusimba kwemvura uye kudzivirira kuputika nekuda kwekubatana kwayo kwakavharwa uye simbi yakasimba.

Ma sensor enzvimbo akakosha pakuita otomatiki kwemaindasitiri. Kune matekinoroji akawanda e sensor enzvimbo pamusika, imwe neimwe ine maitiro ayo akasiyana. Kuti uwane mashandiro anodiwa uye kuvimbika, kungwarira kunofanirwa kuitwa kusarudza mhando chaiyo ye sensor yekushandisa.
