Embonini ye-automation, sivame ukuzwa amagama e-gauge pressure kanye ne-absolute pressure. Ngakho-ke yini i-gauge pressure kanye ne-absolute pressure? Uyini umehluko phakathi kwabo? Isingeniso sokuqala ukucindezela komkhathi.
Umfutho we-atmospheric: Ukucindezela kwekholomu yomoya ebusweni bomhlaba ngenxa yamandla adonsela phansi. Ihlobene ne-altitude, latitude kanye nezimo zezulu.
I-Differential pressure (i-differential pressure)
Umehluko ohlobene phakathi kwezingcindezi ezimbili.
Ukucindezela okuphelele
Zonke izingcindezi endaweni lapho okuphakathi (uketshezi, igesi noma umusi) kutholakala khona. Ukucindezela okuphelele ukucindezela okuhlobene nengcindezi enguziro.
I-gauge pressure (ingcindezi ehlobene)
Uma umehluko phakathi kokucindezela okuphelele nokucindezela komkhathi kuyivelu elihle, khona-ke leli nani eliphozithivu liwukucindezela kwegeji, okungukuthi, ukucindezela kwegeji = ukucindezela okuphelele komkhathi> 0.
Ngokwemibandela ye-layman, ama-gauge okucindezela ajwayelekile akala umfutho wegeji, futhi umfutho womoya womoya uwukucindezela okuphelele. Kunegeji ekhethekile yokulinganisa ingcindezi ephelele yokulinganisa ukucindezela okuphelele.
Thatha ingcindezi ezindaweni ezimbili ezihlukene epayipini. Umehluko phakathi kwezingcindezi ezimbili ingcindezi ehlukile. Isidlulisi sengcindezi esijwayelekile esihlukanisayo sikala ingcindezi ehlukile.
