Magetsi miyezo ya makhalidwe sanali magetsi

miyezo magetsi ndi mkulu molondola, kudalilika, kuphweka ndi cheapness. Choncho, zipangizo za magetsi akhala ankagwiritsa ntchito muyeso ndipo zedi si magetsi.

Dongosolo magetsi kuyeza wambiri si magetsi limapangidwa zigawo zikuluzikulu monga akuti: kachipangizo (transducer), chipangizo wapakatikati ndi chizindikiro.

miyezo magetsi nonelectrical zedi - ichi makamaka kutembenuka kachipangizo nonelectrical zedi, nkuti, kusintha mu msinkhu madzi, liwiro, kutentha, etc., kusintha zosintha magetsi: impedance, voteji kapena panopa chizindikiro cha mpandawo, umene ndi magetsi zipangizo yosavuta ...

The zida ntchito miyezo magetsi anawagawa m'magulu awiri:

• analogi ( "tseshki") - imene zotsatira muyeso pamlingo chipangizo akusonyeza muvi;

• digito - iwo ali analogi ndi digito Converter otembenuka athandizira chizindikiro mu mtengo digito ndi atachitira pa kuwonetsera LCD.

Lero, zipangizo digito m'malo analogi, inu mukhoza kunena, kwathunthu, chifukwa, choyamba:

• ndi wosavuta ntchito (monga kuyenera analogi (muvi), alibe chinthu monga kuyeza kuchuluka kwa kapena lokhoza lonse chida, amene ayenera kulimbana);

• ali kwambiri zolondola analogi.

Tikumbukenso, ndi mwayi makina onga: miyezo magetsi mpata chiyesedwe cha makhalidwe sanali magetsi, ngakhale mwakhama kufika malo kapena kutali kwambiri.

Taonani zitsanzo ziwiri enieni mmene angagwirire miyezo magetsi pogwiritsa ntchito zipangizo kuyeza kuchuluka sanali magetsi.

Wood chinyezi mita

Popeza mitengo - hygroscopic chuma, ndi kusintha mu magawo zachilengedwe zimasintha chinyezi ake - mmodzi wa katundu wa matabwa, omwe ndi ofunika pamene ntchito chotsirizidwa. Choncho, nkhuni nafota ndi mkhalidwe yunifolomu ncholinga zinthu opaleshoni m'tsogolo.

Chimodzi mwa njira kuona wokhutira chinyezi ndi ntchito elektrovlagomerov. Mfundo ntchito mita chinyezi ndi kuyeza chinyezi, zochokera - katundu magetsi. Ndi chipangizo, mukhoza kudziwa mwamsanga popanda kuwononga nkhuni.

Chinyontho mamita ali a mitundu iwiri:

• Singano - iwo zochokera muyeso wa kulimbikira magetsi;

• capacitive (contactless) - iwo zochokera ubale dielectric zonse ndi chinyezi. meters chinyezi izi zimatulutsa izo popanda oyamba singano mu nkhuni. Choncho, pamwamba pa nkhuni osasiya zotsalira pambuyo muyeso, amene kumene, zizindikiro zawo zaphindu chikutanthauza kwa hydrometers singano.

mita ku feteleza

Ku feteleza - izi ndi zina mwa mankhwala amene ali owopsa chifukwa gwero la kuswa m'thupi la munthu. Pamene chakudya lalikulu zedi mu thupi la munthu, angathe kuyambitsa nitrate poizoni, matenda osiyanasiyana aakulu ndi matenda.

Palibe nthawi yambiri ndi mtengo ndondomeko ya kudziwika nitrate panopa ndikukhazikitsa yaing'ono chipangizo wapadera - nitrate.

Nitratomers cholinga kuyeza zipatso, masamba ndi nyama yatsopano ku zili nitrate. Maziko a ntchito chikuyeza ion ntchito elekitirodi dongosolo mwachindunji potentiometric njira, zotsatira za zimene n'kukhala ndi njila magetsi mbendera ndende ion wa NO3.

wapadera kukhudzana kafukufuku (kafukufuku) amaperekedwa kwa liwulo ndi kuyeza njira nitrate mankhwala lancing chipangizo.

Nitrate - chida yadigito. miyezo yake amalembedwa mtundu anasonyeza yabwino.
