Kev Ntsuas Txuj Ci

(1) Kev ntsuas ntau yam (raws li qhov ntsuas ntau yam):

Cov pa oxygen yaj: 0–20.0 mg/L; 0–200%;

kub：-10～150.0℃;

(2) Kev daws teeb meem:

Cov pa oxygen uas yaj: 0.01 mg/L; 0.1%;

kub：0.1℃;

(3) Qhov yuam kev yooj yim:

Yaj lawm cov pa oxygenn: ±1% FS;

kub：±0.3℃;

(4) Lub sijhawm teb (90% tus nqi kawg):

<60 vib nas this ntawm 25°C; <30 vib nas this ntawm 35°C;

（5)kev ruaj khov：

Nyob rau hauv qab atmospheric siab thiab qhov kub thiab txias tas li, qhov kev hloov pauv txhua lub lim tiam yog <2% F·S.

(6) Cov zis tam sim no ntawm ob txoj kab:

0/4 rau 20mA (load tsis kam <750Ω);

20～4mA (kev tiv thaiv thauj khoom <750Ω);

(7) Kev sib txuas lus tso zis: RS485 MODBUS RTU;

(8) Peb pawg ntawm cov relay tswj kev sib txuas:

5A 250VAC,5A 30VDC；

(9) Kev muab hluav taws xob (xaiv tau):

85～265VAC±10%, 50±1Hz, fais fab≤3W;

9–36VDC, kev siv hluav taws xob:≤3W;

(10) Qhov Loj: 235 * 185 * 120mm;

(11) Insttxoj kev faib tawm: Phab ntsa-mounted;

(12) Kev tiv thaiv qib: IP65;

(13) Qhov hnyav: 1.2 kg;

(14) Ib puag ncig ua haujlwm:

Qhov kub thiab txias ib puag ncig: -10 txog 60°C;

Cov av noo sib piv: tsis pub tshaj 90%;

Tsis muaj kev cuam tshuam ntawm lub zog sib nqus muaj zog nyob ib puag ncig tsuas yog lub zog sib nqus ntawm lub ntiaj teb xwb.
