•Signal tso zis: RS-485 (Modbus / RTU raws tu qauv).
• Nws yog qhov yooj yim rau kev txuas mus rau PLC, DCS, muaj kev tswj hwm lub computer, kev tswj xyuas dav dav, cov ntaub ntawv tsis muaj ntaub ntawv lossis lub vijtsam kov thiab lwm yam khoom siv thib peb.
•Dual siab impedance txawv amplifier, muaj zog tiv thaiv kev cuam tshuam, ceev teb.
• Patented pH sojntsuam, cov kua siv sab hauv pom tawm ntawm tus choj microporous ntsev maj mam nyob rau hauv lub siab ntawm tsawg kawg yog 100KPa (1Bar), thiab nws qhov zoo seepage kav ntev tshaj 20 lub hlis. Xws li cov ntaub ntawv siv tau ruaj khov heev, thiab lub neej electrode yog ob npaug piv rau cov khoom siv hluav taws xob zoo tib yam.
•Immersion installation, yooj yim rau nruab rau hauv cov kav dej thiab lub tank.
• Kev tiv thaiv qib IP68.

Siv thiab kho
Thaum ntsuas pH sensor, nws yuav tsum tau muab ntxuav hauv dej distilled (los yog dej deionized) ua ntej, thiab cov dej yuav tsum tau nqus nrog cov ntawv lim kom tsis txhob muaj impurities los ntawm cov kua ntsuas. 1/3 ntawm lub sensor yuav tsum muab tso rau hauv qhov ntsuas ntsuas.
Lub sensor yuav tsum tau muab ntxuav thaum tsis siv, thiab muab tso rau hauv ib tug tiv thaiv npog nrog 3.5 mol / L poov tshuaj chloride tov, los yog muab tso rau hauv ib lub thawv nrog 3.5 mol / L poov tshuaj chloride tov.
Xyuas seb lub davhlau ya nyob twg puas qhuav, yog tias nws muaj xim, so nws nrog cawv thiab tshuab kom qhuav ua ntej siv. Tsis txhob muab tso rau hauv cov dej distilled mus ntev los yog cov kua protein, thiab tiv thaiv kev sib cuag nrog cov roj silicone. Rau cov sensors uas tau siv rau lub sijhawm ntev, nws cov iav daim nyias nyias tuaj yeem ua translucent lossis txuas nrog sediment. Hauv qhov no, nws tuaj yeem ntxuav nrog dilute hydrochloric acid thiab yaug nrog dej. Lub sensor tau siv lub sijhawm ntev, thiab thaum muaj kev ntsuas qhov yuam kev, nws yuav tsum tau ntsuas thiab kho nrog lub ntsuas ntsuas.
Thaum lub ntsuas ntsuas tsis tuaj yeem ntsuas thiab ntsuas thaum lub ntsuas ntsuas tau tswj hwm thiab tswj hwm los ntawm cov txheej txheem saum toj no, nws txhais tau tias lub ntsuas ntsuas ua tsis tiav. Thov hloov lub sensor.
