Hoʻonui i ka pololei o ke ana ʻana: hoʻomaopopo i ka hewa ʻole, pili, a me ka kuhikuhi

Ma ka automation a me ke ana ʻoihana, pono ka pololei. Hōʻike pinepine ʻia nā huaʻōlelo e like me "± 1% FS" a i ʻole "papa 0.5" ma ka ʻikepili mea kani—akā he aha ke ʻano maoli o ia mau mea?

1. Hapa Loa: Pehea ka mamao o kou heluhelu ana?

Wehewehe:

ʻO ka hewa piha ka ʻokoʻa ma waena o ka waiwai i ana ʻia a me ka waiwai maoli o ka nui. Hōʻike ia i ka hoʻokaʻawale maka — maikaʻi a maikaʻi ʻole paha — ma waena o ka mea i heluhelu ʻia a me ka mea maoli.

Kumu:

Laʻana:

Inā he 10.00 m³/s ka helu kahe maoli, a he 10.01 m³/s a i ʻole 9.99 m³/s ka helu kahe ʻana, ʻo ±0.01 m³/s ka hewa loa.

2. Hapa Pili: Ke ana i ka hopena o ka hewa

Wehewehe:

Hōʻike ka hewa pili i ka hala piha ma ke ʻano he pākēneka o ka waiwai i ana ʻia, e maʻalahi ai ka hoʻohālikelike ʻana i nā unahi like ʻole.

Kumu:

Laʻana:

Loaʻa ka hewa 1 kg ma kahi mea 50 kg i ka hewa pili o 2%, e hōʻike ana i ke ʻano nui o ka ʻae ʻana i ka pōʻaiapili.

3. Hapa Kuhikuhi (Full-Scale Error): Metric punahele o ka ʻoihana

Wehewehe:

ʻO ka hewa kuhikuhi, i kapa pinepine ʻia ka hala piha piha (FS), ʻo ia ka hapa paʻa ma ke ʻano he pākēneka o ka laulā hiki ke ana piha o ka mea kani-ʻaʻole ka waiwai i ana ʻia. ʻO ia ka mea hana metric maʻamau e hoʻohana ai e wehewehe i ka pololei.

Kumu:

Laʻana:

Inā he 0-100 bar ka laulā a me ka ± 2 bar ka hewa ʻole, ʻo ±2%FS kona hewa kuhikuhi—kūʻokoʻa i ka heluhelu kaomi maoli.

No ke aha he mea nui: E koho i ka mea hana pono me ka hilinaʻi

ʻAʻole noʻonoʻo wale kēia mau helu kuhi hewa - pili pololei lākou i ka mana kaʻina hana, ka maikaʻi o ka huahana, a me ka hoʻokō hoʻoponopono. Ma waena o lākou, ʻo ka hewa kuhikuhi ka mea i hoʻohana nui ʻia no ka hoʻokaʻawale pololei ʻana i nā mea kani.

Manaʻo Pro: ʻO ke koho ʻana i kahi ʻāpana ana haiki ma kahi mea hana multi-range e hōʻemi ana i ka hala ʻole no ka pololei %FS like—e hoʻomaikaʻi i ka pololei.

E haku i kāu mau ana. E hoonui i kou pololei.

Ma ka hoʻomaopopo ʻana a me ka hoʻohana ʻana i kēia mau manaʻo kuhi hewa ʻekolu, hiki i nā ʻenekinia a me nā ʻenehana ke koho i nā mea kani me ke akamai, wehewehe i nā hopena me ka hilinaʻi, a me ka hoʻolālā ʻana i nā ʻōnaehana pololei i ka automation a me nā kaiapuni.
