Kuthamanga kwa ulusi wowongolera valavu yoyimitsa bidirectional BLF-10

Sensa ya piezoelectric ndi sensor-based sensor ili ndi mawonekedwe osiyanasiyana.

Piezoelectric force sensor imapangidwa ndi magawo a piezoelectric crystal, omwe amapanga ndalama akamakakamizidwa. Kawirikawiri, electrode imayikidwa pakati pa magawo awiri, yomwe imatenga ndalama zomwe zimapangidwira, ndipo chipolopolo chozungulira chimagwiranso ntchito ngati electrode. Ubwino wa pamwamba pa kristalo ndi chipolopolo cha piezoelectric sensor ndipamwamba kwambiri, ndipo ndizofunikira kwambiri pamtundu woyezera (mzere, machitidwe oyankha) wa mphamvu ya mphamvu.

Kaya kugwiritsa ntchito kupsinjika kapena mphamvu yotengera mphamvu zotengera mphamvu zimatengera kugwiritsa ntchito. Masensa a piezoelectric amakondedwa pamagwiritsidwe otsatirawa:

Malo oyika sensa ndi ochepa.

Kuyeza kwamphamvu kochepa komwe kumakhala ndi katundu woyambirira

Kutalikirana koyezera

Kuyeza pa kutentha kwambiri

Kukhazikika kochulukira kwambiri

Zamphamvu kwambiri

M'munsimu, tidzafotokozera mwatsatanetsatane magawo ake ogwiritsira ntchito ndikukupatsani chiwongolero cha masankhidwe a masensa.

Ntchito minda ya piezoelectric masensa;

1. Malo oyika sensa ndi ochepa.

Masensa a piezoelectric ndi ophatikizika kwambiri, mwachitsanzo, mndandanda wa CLP ndi 3 mpaka 5 mm kutalika (malingana ndi kuchuluka kwake). Chifukwa chake, sensor iyi ndi yoyenera kwambiri kuphatikiza ndi zida zomwe zilipo. Masensa ali ndi chingwe chophatikizika, chifukwa sangathe kunyamula mapulagi, kotero kutalika kwake kumakhala kochepa kwambiri. Sensa ili ndi makulidwe onse a ulusi, kuyambira M3 mpaka M14. Kutalika kochepa kwa kamangidwe kameneka kumafuna kuti mphamvu pa sensa pamwamba igawidwe mofanana.

2. Muyezo wa mphamvu yaying'ono yokhala ndi katundu wambiri woyamba

Mphamvu ikagwiritsidwa ntchito, sensor ya piezoelectric imapanga mtengo wamagetsi. Komabe, sensa imayikidwa ndi mphamvu yomwe imaposa muyeso weniweni, mwachitsanzo, panthawi yoika. Mtengo wopangidwa ukhoza kukhala wozungulira, ndikuyika chizindikiro pakulowetsa kwa amplifier mpaka zero. Mwanjira imeneyi, muyeso woyezera ungasinthidwe molingana ndi mphamvu yeniyeni yoyezedwa. Chifukwa chake, ngakhale katundu woyambayo atakhala wosiyana kwambiri ndi mphamvu yoyezera, kuyeza kwakukulu kumatha kutsimikizika. Ma amplifiers apamwamba kwambiri monga CMD600 amatha kusintha mosalekeza muyeso munthawi yeniyeni, motero amathandizira izi.

3. Wide kuyeza osiyanasiyana

Masensa a piezoelectric alinso ndi maubwino pamagawo angapo. Choyamba, pamene mphamvu yaikulu ikugwiritsidwa ntchito poyamba. Sinthani tcheni choyezera cha piezoelectric moyenerera. Gawo lachiwiri limakhudza kutsata mphamvu, ndiko kuti, kuyeza kusintha kwamphamvu pang'ono. Kupindula ndi ntchito zapadera za sensa ya piezoelectric, kuphatikiza kuchotsa chizindikirocho pakulowetsa kwa amplifier. Kuyika kwa amplifier kwa charger kumatha kukhazikitsidwanso ku zero ndipo mulingo woyezera ukhoza kusinthidwa kuti muwonetsetse kuti pali kusintha kwakukulu.
