ʻO ka mea hōʻailona hōʻailona IQS900 he mea maʻalahi a hiki ke hoʻonohonoho ʻia e hana i nā hōʻailona hōʻailona e pono ai a hoʻopuka i ka hōʻailona puka (i kēia manawa a i ʻole ka uila) no ka hoʻokomo ʻana i kahi ʻōnaehana nānā mīkini e like me VM600Mk2/VM600. Eia kekahi, kākoʻo ka IQS900 i ka circuit diagnostic koho (ʻo ia hoʻi, ka hoʻāʻo ponoʻī i kūkulu ʻia (BIST)) e ʻike ʻakomi a hōʻike mamao i nā pilikia me kahi kaulahao ana.

Loaʻa i ka mea hōʻailona hōʻailona IQS900 kahi modulator / demodulator kiʻekiʻe e hāʻawi ana i kahi hōʻailona hoʻokele i kahi sensor TQ9xx. Hoʻopuka kēia i kahi kahua electromagnetic ma ka piko o ka mea ʻike, e hoʻohua ai i nā eddy-currents i ka pahu metala. Ke neʻe ka pahu hopu, hoʻololi nā eddy-currents, kahi e hoʻololi ai i nā hiʻohiʻona uila o ka TQ9xx e hoʻololi ai ka mea hoʻomaʻamaʻa hōʻailona i kahi hōʻailona e kūlike me ka mamao i ka pahuhopu. ʻO ka hoʻopuka o ka IQS900 he hōʻailona hoʻohālikelike i loaʻa i kahi mea hoʻoikaika (AC) e pili ana i ka vibration i ana ʻia (ka hoʻoneʻe) a me kahi ʻāpana quasistatic (DC) e pili ana i ke ana i ana ʻia. Hiki ke hoʻonohonoho ʻia ka mea hoʻopuka e like me ka hōʻailona o kēia manawa a i ʻole ka hōʻailona uila, kūpono no ka hoʻouna ʻana i kahi ʻōnaehana kiaʻi ma o nā kaula uila (2-wire) a i ʻole ka uila (3-wire). No ka mea hoʻomaʻamaʻa hōʻailona IQS900 me nā diagnostics koho, hana pū ka mea quasi-static DC ma ke ʻano he hōʻailona diagnostics. ʻO ia hoʻi, ʻo ka IQS900's diagnostic circuitry e nānā mau i ka pono o ke kaulahao ana a e hoʻokuke i ke ana/diagnostic component (DC) ma waho o kona ʻano hana maʻamau e hōʻike i kahi pilikia me ka mea ʻike, ke kelepona a/a i ka mea hōʻailona hōʻailona ponoʻī. No ka hoʻāʻo ʻana, hāʻawi ka IQS900 i kahi hōʻailona puka uila "raw" a kākoʻo i kahi hōʻailona hoʻokomo uila hoʻāʻo e hiki ai ke hoʻāʻo ʻia ke kaulahao ana / ʻōnaehana hana ma kahi, a laila e hoʻomaʻamaʻa i ke komisina a me ka hoʻoponopono pilikia.

ʻO ka hoʻopuka hōʻailona hōʻailona IQS900 he hōʻailona ikaika kūpono no ka nānā ʻana i nā spectral. No laila, ʻōlelo ʻia ka IQS900 no ka pale ʻana i nā mīkini a / a i ʻole nā ​​​​noi ka nānā ʻana i ke kūlana kiʻekiʻe. No nā noi maʻamau, ʻoi aku ka maikaʻi o kahi hōʻailona hoʻopuka lohi e like me ka mea i hāʻawi ʻia e ka mea hōʻailona hōʻailona IQS910. E nānā i ka pepa ʻikepili hōʻailona hōʻailona IQS910 no ka ʻike hou aku. ʻO kahi mea hōʻailona hōʻailona IQS900 me nā diagnostics e hōʻike maʻalahi a hōʻike mamao aku i ke olakino/ kūlana o kahi kaulahao ana TQ9xx no laila ʻike mau ʻoe i ka wā hiki ke hilinaʻi ʻia nā ana. Kōkua kēia i ka mālama pono ʻana o nā mīkini me ka palekana a me ka hilinaʻi, e hoʻolōʻihi i kona ola a hōʻemi i nā kumukūʻai. ʻO ka mea nui, ʻo nā kaulahao ana TQ9xx me ka hoʻohana ʻana i ka IQS900 me nā diagnostics ʻo SIL 2 "ma ka hoʻolālā" no laila e lawe mai lākou i ka hilinaʻi i hoʻonui ʻia a me ka hōʻemi nui ʻana i ka pilikia, e kūpono ia no ka hoʻohana ʻana i nā noi e pili ana i ka palekana (nā pōʻaiapili palekana hana)

Ka puka ʻana o kēia manawa (2-wire signal transmission) ʻO kēia ma ka min. / max. āwaha : −15.5 mA / −20.5 mA Ana ana: 5 mA (e pili ana i ka 2 a i ʻole 4 mm) Naʻauao puka: E nānā i ka hana ma ka ʻaoʻao 3 a me IQS900 hōʻailona hōʻailona ma ka ʻaoʻao 18 Nominal output signal • Me ka ʻole o ka diagnostics: −15.5 a i −5. −20.5 mA hōʻike i ka hana maʻamau. ʻO nā waiwai ʻē aʻe o kēia manawa (>−15.5 a i ʻole <−20.5 mA) e hōʻike ana i kahi pilikia me ke kaulahao ana (sensor, cabling a i ʻole ka mea hōʻailona hōʻailona). Ka hoʻokuʻu ʻana: >60 kΩ. Nānā: Manaʻo ʻia ka nānā ʻana i ka ʻōnaehana hoʻokomo impedance: ≤350 Ω. Voltage output (3-wire signal transmission) Voltage ma min. / max. āwāwa: −1.6 V / −17.6 V Ana ʻana: 16 V (e like me 2 a i ʻole 4 mm) ʻO ka ʻike puka: E nānā i ka hana ma ka ʻaoʻao 3 a me IQS900 mea hoʻomaʻamaʻa hōʻailona ma ka ʻaoʻao 18 Hōʻailona hōʻailona inoa • Me ka ʻole o ka diagnostics: −1.6 a i −17.6 a i −17.6 V • Hōʻike ʻo V i ka hana maʻamau. Hōʻike ʻia nā kumu waiwai ʻē aʻe (>−1.6 a i ʻole <−17.6 V) i kahi pilikia me ke kaulahao ana (sensor, cabling a i ʻole ka hōʻailona hōʻailona). Ka hoʻokuʻu ʻana (hōʻailona liʻiliʻi): <100 Ω ma DC. <300 Ω ma 20 kHz. Nānā: Manaʻo ʻia ka nānā ʻana i ka ʻōnaehana hoʻokomo impedance: ≥50 kΩ. Hiki i ka impedance puka haʻahaʻa ke hana me kahi ākea ākea o nā ʻāpana hoʻokaʻawale galvanic / pale palekana, me ka ʻole o ka nalowale o ka hana. No ka laʻana, he IQS900 (output impedance 100 Ω) i hoʻopili ʻia i kahi mea hoʻokaʻawale galvanic ʻaoʻao ʻekolu (input impedance 10 kΩ) e ʻike i ka 1% max. nalo ka hōʻailona ma muli o ka hoʻohālikelike impedance.
