MD-G3051Meokon-Lub Tsev-Pov-Tawg-nrog-IP67-Kev Lag Luam

Cov kev ua haujlwm tsis zoo:
1. Scope ntawm kev siv: kua, roj thiab pa.
2. Cov teeb liab tso zis: ob txoj hlau system 4 ~ 20mA cais DC teeb liab superimposed HART digital teeb liab tso zis, linear lossis square root tso zis tuaj yeem xaiv, qhov tso zis siab tshaj plaws tam sim no tsis pub ntau tshaj 22mA.
3. Lub hwj chim muab: DC 12 ~ 45V; HART kev sib txuas lus, lub hwj chim muab hluav taws xob ntau yam: 15.5 ~ 45V DC; Lub zog ua haujlwm dav dav: 24V DC.
4. Qhov ntau ntawm kev thauj khoom: HART kev sib txuas lus, qhov tsis kam hauv lub voj voog fais fab yog ntau dua 250 Tebchaws Europe, qhov hluav taws xob muab hluav taws xob ntau dua 15.5 volts.
5. Kev sib txuas lus deb: lub txoj kab uas hla ntawm cov xov hlau txuas yog ntau dua 0.6 hli, thiab kev sib txuas lus deb yog li 1500m.
6. Cov khoom siv tso saib: ntse LCD kua siv lead ua kua backlight 5-lej zaub; Siv kev sib xyaw ua ke ntawm
LCD Cov yuam sij M, Z, thiab S ntawm cov kua siv lead ua kua, qhov zaub tuaj yeem ua cyclic lossis fixed display: KPa, mA, %, mmH2O, MPa, Pa, bar, ATM, PSI, Torr thiab lwm yam engineering units, tuaj yeem siv yam tsis muaj kev nyuaj siab los hloov qhov ntsuas ntau yam (passive migration), teeb tsa qhov tso zis tam sim no ruaj khov, hloov kho lub sijhawm damping, teeb tsa linear, square output thiab backup thiab restore cov ntaub ntawv thiab lwm yam haujlwm.
7. Kev hloov pauv xoom thiab ntau yam: qhov txwv qis dua ntawm qhov ntsuas yuav tsum tsis txhob qis dua qhov txwv qis dua ntawm qhov ntsuas siab tshaj plaws, thiab qhov txwv siab tshaj plaws yuav tsum tsis txhob tshaj qhov txwv siab tshaj plaws ntawm qhov ntsuas siab tshaj plaws, uas yog, qhov ua haujlwm yuav tsum tsis txhob tshaj qhov txwv ntawm lub sensor. Qhov xoom thiab ntau yam tuaj yeem teeb tsa ntawm txhua qhov chaw sib xws los ntawm 4 txog 20mA.
8 xoom siab zoo tuning: siv M + Z khawm kom tshem tawm xoom, kho qhov kev hloov pauv ntawm qhov chaw teeb tsa transmitter lossis xoom drift los ntawm qhov yuam kev, lub transmitter siab hloov kho rau xoom siab tus nqi.
9 tus nqi tsis kam: hluav taws xob damping kho tau ntau yam ntawm 0 ~ 32 vib nas this.
10. Lub tswb ceeb toom txhaum cai: Thaum qhov kev pab cuam kuaj mob tus kheej pom qhov txhaum, qhov tso zis analog siab dua 20.8mA lossis qis dua 3.9mA.
11. Kev rov qab tau cov ntaub ntawv: thaum cov ntaub ntawv puas lawm, cov ntaub ntawv puas tsuaj tuaj yeem rov qab tau los ntawm peb lub khawm.
12. Kev them nyiaj kub: lub khoos phis tawj sau cov ntaub ntawv kub thiab xa mus rau lub transmitter rau kev them nyiaj kub.
13. Qhov ntsuas kub: qhia txog tus nqi kub ntawm lub transmitter.
14. Kev kub ua haujlwm: hluav taws xob hluav taws xob: -40 ~ + 85ºC, nrog LCD LCD: -30 ~ + 80ºC; Cov khoom rhiab heev (muaj roj silicone puv): -40 ~ + 104ºC;
15 qhov kub cia: -45 ~ + 90ºC.
16. Kev tiv thaiv kev nyab xeeb: THIAB tsim kev tiv thaiv Circuit Court, kev cuam tshuam tiv thaiv static, tam sim no surge, kev tiv thaiv overload muaj zog heev.
