Sensor yothamanga kwambiri ya kutentha
Kodi sensor ya kutentha kwapamwamba ndi chiyani?
Sensa yothamanga kwambiri ndi piezoelectric sensor yomwe imatha kuyeza zovuta pa kutentha kosalekeza mpaka 700 ° C (1.300 ° F).Kugwira ntchito ngati kasupe-mass system, ntchito zofananira zimaphatikizirapo njira zomwe ma pulsation amphamvu amayenera kuyesedwa ndikuwongolera.Chifukwa cha kristalo ya PiezoStar yomwe inamangidwa, mphamvu yotentha kwambiri imapirira kutentha mpaka 1000 ° C (1830 ° F) panthawi yochepa.Kupyolera mu teknoloji yosiyana ndi kubwezeredwa kwa mathamangitsidwe omangidwa, phokoso lochepa komanso kulondola kwakukulu kumatheka.Chingwe chokhazikika chokhazikika chomwe chimapangidwira kutentha kwambiri chimalumikiza sensa ndi amplifier.
Kodi masensa am'madzi otentha amagwiritsidwa ntchito chiyani?
Makanema othamanga kwambiri amagwiritsidwa ntchito poyezera ndi kuwongolera njira zoyatsira zamphamvu, mwachitsanzo m'magalasi amagetsi ndi ntchito zofananira za thermoacoustic.Amajambula molondola kugunda kwamphamvu komwe kungakhale koopsa komanso kugwedezeka kuti athe kuwongolera magwiridwe antchito.
Kodi tcheni choyezera cha masensa othamanga kwambiri amapangidwa bwanji?
Kupatula masensa okha, ma amplifiers ophatikizira osiyanitsa ndi zingwe zolimba zaphokoso zotsika komanso zofewa zimatsimikizira kuti muyeso wapamwamba umakwaniritsidwa.Kuphatikiza apo, zida zomwe zidatsimikiziridwa kale zimagwiritsidwa ntchito m'malo ovuta.
Ndi mitundu yanji ya masensa omwe ali ndi kutentha kwambiri?
Masensa othamanga kwambiri amapezeka m'mitundu yosiyanasiyana, pakati pawo ang'onoang'ono komanso opepuka pazolinga zofufuza ndi chitukuko.Kutengera ndi zofunikira za pulogalamu inayake, kutalika kwa chingwe ndi mitundu yolumikizira ndizotheka.Kuphatikiza apo, mitundu yotsimikizika (ATEX, IECEx) imagwiritsidwa ntchito m'malo owopsa.
Masensa a kutentha kwapamwambaamaperekedwa kuti agwiritsidwe ntchito pa kutentha kwakukulu.Monga tonse tikudziwira kuti masensa wamba wamba sangathe kugwira ntchito m'malo otentha kwambiri kwa nthawi yayitali ngati palibe njira zodzitetezera.
Kuti apereke mayankho ogwiritsira ntchito kutentha kwakukulu, masensa othamanga kwambiri amapangidwa popanda njira zina zowonjezera.Sensa yamtunduwu imatha kugwira ntchito kutentha mpaka 200 ℃.Kapangidwe kake kapadera kamadzimadzi kamachepetsa kutentha kwambiri, komwe kumateteza bwino sensa makamaka pachimake polimbana ndi kuukira kwadzidzidzi kwa sing'anga yapamwamba.
Koma ngati masensa wamba kuthamanga ntchito ntchito ngati zimenezi osatizoyezera kutentha kwapamwamba, ndiye njira zotetezera ziyenera kuchitidwa kuti zisawonongeke kuzungulira dera, magawo, mphete yosindikiza ndi pachimake.M'munsimu muli njira zitatu.
1. Ngati kutentha kwa sing'anga yoyezera kuli pakati pa 70 ndi 80 ℃, yonjezerani radiator ku sensa yothamanga ndi malo olumikizira kuti muchepetse kutentha moyenerera sing'angayo isanagwirizane ndi chidacho.
2. Ngati kutentha kwa sing'anga yoyezera kumakhala 100 ° C ~ 200 ° C, ikani mphete ya condenser pamalo olumikizirana ndikuwonjezera radiator, kuti kutentha kuzitha kuzimiririka ndi ziwirizo musanakumane mwachindunji ndi sensor yamphamvu. .
3.Kuyeza kutentha kwakukulu kwambiri, chubu chowongolera chiwongolero chikhoza kufalikira kenako ndikugwirizanitsa ndi makina othamanga, kapena onse a capillary chubu ndi radiator akhoza kuikidwa kuti akwaniritse kuzizira kwapakati.
