(Tsis muaj feem xyuam rau Multi-point kub sensor hom T-MP / W-MP lossis T-MPT / W-MPT nrog cais Exi circuits).
Kev suav rau qhov kub siab tshaj plaws:
Kev ntsuas tus kheej ntawm qhov ntsuas qhov taw qhia tuaj yeem xam los ntawm cov mis:
Tmax = Po × Rth + MT
Tmax) = Qhov kub siab tshaj plaws = qhov kub thiab txias ntawm qhov ntsuas qhov taw qhia
(Po) = Lub zog pub mis siab tshaj plaws rau lub sensor (saib daim ntawv pov thawj transmitter)
(Rth) = Thermal resistance (K/W, Table 3.)
(MT) = nruab nrab kub.
Xam qhov kub siab tshaj plaws ntawm qhov kawg ntawm lub sensor:
Example 1 – Xam rau RTD-sensor tip nrog thermowell
Sensor siv ntawm Zone 0 RTD sensor hom: WM-9K . . . (RTD-sensor nrog lub taub hau-mounted transmitter). Sensor nrog thermowell, txoj kab uas hla ntawm Ø 9 mm. Qhov nruab nrab kub (MT) yog 120 ° C Kev ntsuas yog tsim nrog PR electronics lub taub hau mounted transmitter 5437D thiab cais barrier PR 9106 B. Qhov kub siab tshaj plaws (Tmax) tuaj yeem suav tau los ntawm kev ntxiv qhov kub ntawm qhov nruab nrab uas koj ntsuas thiab ntsuas tus kheej. . Qhov ntsuas kub ntawm tus kheej ntawm lub ntsuas ntsuas tuaj yeem suav los ntawm lub zog siab tshaj plaws (Po) uas yog pub rau lub sensor thiab Rth-tus nqi ntawm kev siv hom sensor. (Saib daim duab 3.)
Muab hluav taws xob los ntawm PR 5437 D yog (Po) = 23,3 mW (los ntawm lub transmitter Ex-certificate) Kub chav kawm ntawv T4 (135 ° C) yuav tsum tsis txhob tshaj. Thermal resistance (Rth) rau lub sensor yog = 55 K / W (los ntawm Table 3). Kev ntsuas tus kheej yog 0.0233 W * 55 K / W = 1,28 K Qhov siab tshaj plaws (Tmax) yog MT + nws tus kheej cua sov: 120 ° C + 1,28 ° C = 121,28 ° C Qhov tshwm sim hauv qhov example qhia tau hais tias, qhov cua sov ntawm tus kheej ntawm qhov ntsuas ntsuas yog qhov tsis txaus ntseeg. Cov npoo kev nyab xeeb rau (T6 txog T3) yog 5 ° C thiab qhov yuav tsum tau muab rho tawm ntawm 135 ° C; txhais tau hais tias mus txog 130 ° C yuav tau txais. Hauv no example qhov kub ntawm chav kawm T4 tsis tshaj.
Example 2 – Xam rau RTD-sensor ntsis yam tsis muaj lub thermowell.

Qhov kub siab tshaj plaws (Tmax) tuaj yeem suav tau los ntawm kev ntxiv qhov ntsuas kub ntawm qhov nruab nrab uas koj ntsuas thiab ntsuas tus kheej. Cov cua kub ntawm tus kheej ntawm cov lus qhia sensor tuaj yeem suav los ntawm lub zog siab tshaj plaws (Po) uas yog pub rau lub sensor thiab Rth-tus nqi ntawm hom siv sensor. (Saib daim duab 3.)
Muab hluav taws xob los ntawm PR 9113D yog (Po) = 40,0 mW (los ntawm lub transmitter Ex-certificate) Kub chav kawm ntawv T3 (200 ° C) yuav tsum tsis txhob siab tshaj. Thermal resistance (Rth) rau lub sensor yog = 100 K / W (los ntawm Table 3). Kev ntsuas tus kheej yog 0.040 W * 100 K / W = 4,00 K Qhov siab tshaj plaws (Tmax) yog MT + nws tus kheej cua sov: 40 ° C + 4,00 ° C = 44,00 ° C Qhov tshwm sim hauv qhov example qhia tau hais tias, qhov cua sov ntawm tus kheej ntawm qhov ntsuas ntsuas yog qhov tsis txaus ntseeg. Cov npoo kev nyab xeeb rau (T6 txog T3) yog 5 ° C thiab qhov yuav tsum tau muab rho tawm ntawm 200 ° C; txhais tau hais tias mus txog 195 ° C yuav tau txais. Hauv no example qhov kub ntawm chav kawm T3 tsis tshaj.
Cov ntaub ntawv ntxiv rau pab pawg II: (acc. rau EN IEC 60079 0: 2019 ntu: 5.3.2.2 thiab 26.5.1)
Chav kawm kub rau T3 = 200 ° C
Chav kawm kub rau T4 = 135 ° C
Kev nyab xeeb margin rau T3 rau T6 = 5 K
Kev nyab xeeb margin rau T1 txog T2 = 10 K.
Nco tseg!
