Zitha kuwoneka kuchokera pa Gulu 1 kuti ma 3051/1151 ma capacitive transmitters opangidwa ndi kampani yathu ndi athunthu mosiyanasiyana, ndipo ogwiritsa ntchito amatha kuwasankha mosasamala malinga ndi zosowa zosiyanasiyana.Kuphatikiza pa chitsulo chosapanga dzimbiri cha 361L, zinthu zonyowa zilinso ndi zokutira za Hastelloy C, Monel, SIOCFLON, ndi zina zambiri, zomwe zingagwiritsidwe ntchito kuyeza media zowononga.
Ma transmitters amtundu wa 3051-1151 ndi ophatikizika, osavuta kukhazikitsa, kugwiritsa ntchito ndikusintha.Mpanda wamagetsi umakhala ndi ma cavity awiri, ndiye kuti, terminal block ndi amplifier circuit iliyonse imakhala pabowo.Kupanda mpweya ndi kwabwino, ndipo kuli ndi mawonekedwe osaphulika komanso nyengo yonse.Dongosolo la amplifier lili ndi chitetezo cha reverse polarity kuteteza kuwonongeka kwa transmitter chifukwa cha kulumikizidwa kolakwika kwa polarity yamagetsi.Popeza kusintha kwa voliyumu ya transmitter ndi yochepera 0.16cm3 ikugwira ntchito, palibe chifukwa chowonjezera condenser kapena silinda yamadzimadzi kuti mubwezere kusintha kwa voliyumu.
Ma transmitters amtundu wa 3051/1151 opangidwa ndi kampani yathu amatha kukhala ndi chizindikiro cha 0 ~ 100% pazowonetsa patsamba;atha kukhalanso ndi chowonera cha digito chowonetsera patsamba.Chiwonetserocho ndi 31/2 nthawi LCD kapena chiwonetsero cha LED, komanso kuwerenga molondola ± 0.5% + 1 mawu, chifukwa chosinthira A/D, amplifier, crystal yamadzi, ndi zina zotere zimagwiritsa ntchito zida zapamwamba kwambiri zolondola, zolimba komanso zodalirika.Ogwiritsa ntchito amatha kusankha malinga ndi zizolowezi zawo.

The 3051 / 1151DP · GP transmitter imakhala kupanikizika kwakutali kosiyana kapena kuponderezedwa pambuyo pokhala ndi chipangizo chosindikizira chakutali.Ma transmitter akutali amatha kupewa kulumikizana mwachindunji pakati pa sing'anga yoyezera ndi diaphragm ya transmitter.
Malo oyenerera
1. Sing'anga yoyezera imakhala ndi zowononga pa cholumikizira cholumikizira ndi zigawo zomvera;
2. Ndikofunikira kupatulira sing'anga yoyezera kutentha kwambiri kuchokera ku transmitter;
3. Pali zinthu zolimba zoyimitsidwa kapena kukhuthala kwakukulu mu sing'anga yoyezera, yomwe ndi yosavuta kuletsa cholumikizira cholumikizira ndi chipinda chopanikizika;
4. Mikhalidwe yaukhondo iyenera kutetezedwa kuti isatengedwe.
Kuyeza: 0 ~ 6kPa-0 ~ 10Mpa
Zida zosiyanasiyana zamapangidwe zimaperekedwa, ndipo mawonekedwe owotcherera a zigawo za chipangizo chotumizira kutali ndi odalirika kwambiri.Mapangidwe otsika kwambiri amadzimadzi odzaza madzi amachepetsa kutentha.Malinga ndi zofunikira za ogwiritsa ntchito, kutentha kwamafuta a silicone wamba ndi -40+149 ° C;Matenthedwe ogwiritsira ntchito amafuta a silicone omwe amatenthedwa kwambiri ndi 15-315 ° C, onani Gulu 23 kuti mumve zambiri.
Malire apamwamba a kupanikizika kogwira ntchito kwa chipangizo chotumizira kutali ndi mtengo wamtengo wapatali wa chipangizo chakutali chosankhidwa ndi wogwiritsa ntchito;kuthamanga kwa ntchito sikuyenera kukhala kotsika kuposa 3.5kPa (kuthamanga kwathunthu).Pazankhani zowononga, chonde onani Table 25 kuti musankhe chojambula chodzipatula (chokhacho chongowonetsa posankha ndi wogwiritsa ntchito).
