Features
1.1) Vhura chimiro
1.2) Yakakwana uye yakareruka uremu
1.3) Kunzwa kwakanyanya uye kumanikidza kwenzwi
1.4) Kuderera kwesimba rekushandisa
1.5) Kuvimbika kwepamusoro
1625T Ultrasonic transmitter chikamu chepakati chechimbo chemagetsi chinodzinga zvipembenene chinoshandisa high-frequency ultrasonic circuit ine kutsvaira frequency kugadzira 22-55KHZ kutsvaira frequency ultrasonic mafungu.Tsvagiridzo yesainzi yakaona kuti zvipembenene zvakaita seumhutu, mapete, uye mbeva zvinogona kukonzera kukanganisa mune yavo endocrine system uye physiological mabasa mukati meiyi frequency renji, nekudaro vachiwana mhedzisiro yekudzinga nekuuraya.

Nhanganyaya kune Ultrasonic Sensors
Ultrasonic sensors ma sensor akagadzirwa achishandisa maitiro e ultrasound.Ultrasonic sensors inoshandisa piezoelectric mhedzisiro yepiezoelectric ceramics.Kana chiratidzo chemagetsi chikaiswa kune piezoelectric ceramic plate, inokonzeresa, zvichiita kuti sensor idengenyeke uye inoburitsa masaisai e ultrasonic.Kana Ultrasound ikarova chipingamupinyi, inoratidzira kumashure uye inobata pane piezoelectric ceramic ndiro kuburikidza ne sensor.Kubva pane inverse piezoelectric effect, iyo ultrasound sensor inogadzira chiratidzo chemagetsi kubuda.Nekushandisa iyo musimboti wekuramba uchiparadzira kumhanya kwemafungu e ultrasonic mune imwechete svikiro, chinhambwe chiri pakati pezvipingamupinyi chinogona kutariswa zvichibva pamusiyano wenguva pakati pekutumira nekugamuchira masaini.Ultrasonic masaisai anozoburitsa akakosha echiratidziro paanosangana netsvina kana nzvimbo, uye Doppler mhedzisiro pavanosangana nezvinhu zvinofamba.Naizvozvo, ma ultrasonic sensors anoshandiswa zvakanyanya mumaindasitiri, kushandiswa kwevanhu, kudzivirira kwenyika, biomedicine, uye mamwe minda.
Applications
1. Automotive anti-collision radar, ultrasonic rangeng system, ultrasonic proximity switch;
2. Zvishandiso zvechiremote zvemidziyo yemumba, matoyi, uye zvimwe midziyo yemagetsi;
3. Ultrasonic emission uye midziyo yekugamuchira yekurwisa-kuba uye midziyo yekudzivirira njodzi.
4.Inoshandiswa kudzinga umhutu, zvipembenene, mhuka, nezvimwe.
