Teb ceev (TL; DR)
Yog tias koj xav tau cov lus teb ceev ceev: ib qho kev lag luam propane tank qib sensor yog qhov ruaj khov, txaus ntshai - cheeb tsam- ntsuas ntsuas (feem ntau coj-wave radar, magnetostrictive, los yog siab-raws li) uas ntsuas LPG hauv cov tso tsheb hlau luam ntau thiab tshaj tawm tshaj 4-20 mA, HARTRS-48bus, lossis Mod Nws xa cov ntaub ntawv txuas mus ntxiv, tej thaj chaw deb khoom rau kev nyab xeeb, tsis siv neeg xa khoom xa tuaj, thiab ua raws li cov qauv xws li NFPA 58.
Dab tsi yog Industrial Propane Tank Level Sensor?
Muaj LPG cia li ntawm 500-gallon cylinders mus rau 30,000-gallon bulk nkoj thiab spheres loj ntawm cov khoom xa tawm. Ib qho kev lag luam qib sensor yog tsim los rau ib puag ncig: nws tiv taus huab cua, kev vibration, thiab vaporable vapor, nqa cov ntawv pov thawj qhov chaw txaus ntshai (ATEX, IECEx, lossis UL / NEC Class I Division 1/2), thiab hais txog cov nroj tsuag tswj kev cai. Tsis zoo li lub pas ntsuas los yog qhov pom iav, nws muab lub teeb liab nyob, automatable.
Yuav ua li cas Industrial Propane Monitoring Ua Haujlwm
Ntsuas- Lub sensor txiav txim siab ua kua siab siv radar, magnetostriction, siab, lossis ultrasound.
Hloov- Lub ntsuas ntsuas hloov qhov ntsuas mus rau hauv tus qauv teeb liab (4-20 mA, HART, lossis digital).
Kev xa tawm- Lub teeb liab taug kev hla lub voj voog lossis RS-485 tsheb npav mus rau chav tswj.
Ua ke- PLC, RTU, lossis SCADA cov neeg sau keeb kwm ingests thiab timestamps tus nqi.
Ua- Lub kaw lus qhia qib, kev kwv yees rov qab, ceeb toom rau siab / qis, thiab tuaj yeem ua rau xa lossis kaw.
