I-Daviteq MBRTU-SAL ye-Salinity Sensor Modbus RTU Output
Olu xwebhu lusetyenziselwa ezi mveliso zilandelayo.
Intshayelelo
MBRTU-SAL sisivamvo setyuwa esekwe kumlinganiso we-electrodeless inductive. Isebenzisa i-generator ukuvelisa intsimi yamagnetic etshintshanayo kwikhoyili ephambili ukuvelisa i-current induced in the medium. Ubuninzi be-current induced kuxhomekeke ekugxininiseni kwe-ion phakathi. I-current induced idala enye intsimi yamagnetic kwikhoyili yesibini. Ummkeli ulinganisa i-current induced kwi-coil ukumisela ubutyuwa be-medium. Ngelo xesha, i-sensor yeqondo lokushisa eyakhelwe-ngaphakathi inokuhlawulela ngokuzenzekelayo ubushushu, obufanelekileyo kwi-intanethi yokubeka iliso ixesha elide lokusingqongileyo.
Umda wesicelo: Amanzi olwandle, amdaka akwimizi-mveliso, amayeza, iteknoloji yebhayoloji, ukwenziwa kwamashishini kunye nolunye uhlolo lwenkqubo ye-intanethi.
Iimbonakalo
- Inzwa yeqondo lokushisa eyakhelwe-ngaphakathi inokuhlawula ngokuzenzekelayo ubushushu
