I-PHD-12TZ-*11
Isishwankathelo
Isithintelo sokhuseleko esizimeleyo: I-PHD-12TZ-*11, igalelo lesiginali ye-RTD, igalelo elinye kunye negalelo eliphindwe kabini.
Umqobo wokhuseleko ozimeleyo unokuguqula isignali yokufaka ye-RTD kwindawo enobungozi ibe yi-4-20mA signal output kwaye uyithumele kwindawo ekhuselekileyo. Isekethe ixhotyiswe nge-single RTD signal input kunye ne-DC dual output.
Isignali yesiphumo se-4-20mA, ingacwangciswa ngobuchule. Uluhlu lokwenyani lwe-RTD lunokubekwa yikhompyutha.
I-PHD-12TZ-*11, "*" ibonisa uhlobo lokufaka lwe-RTD, nceda sebenzisa ikhowudi ukubonisa.
Le mveliso ifuna umbane wangaphandle we-20 ~ 35VDC.
Iintlobo zesignali yokufaka kunye noluhlu lokulinganisa
| Ikhowudi | Imodeli ye-RTD | Uluhlu lokulinganisa | Uluhlu oluncinci | Ukuchaneka kokuguqulwa |
| 1 | G53 | -50~150℃ | 20℃ | 0.2℃/0.1% |
| 2 | I-Cu50 | -50~150℃ | 20℃ | 0.2℃/0.1% |
| 4 | I-Pt100 | -200~850℃ | 20℃ | 0.2℃/0.1% |
| 6 | I-Pt1000 | -200~850℃ | 20℃ | 0.2℃/0.1% |
| 7 | I-Ni1000 | -60~250℃ | 20℃ | 0.2℃/0.1% |
Umzekelo: Igalelo lokhuseleko oluzimeleyo lwe-Pt100, ubushushu obuphakathi kwe-0 ~ 400℃, kunye neziphumo ezimbini ze-4 ~ 20mA, umbane ophakathi kwe-20 ~ 35VDC, imodeli yi-PHD-12TZ-411 (0 ~ 400℃), umlinganiselo ungamiselwa kuluhlu oluchaziweyo lwe-0 ~ 400℃ yikhompyutha.

2. Umsebenzi wesitimela samandla ngumsebenzi onganyanzelekanga, kwaye abasebenzisi kufuneka bacacise indlela yokubonelela ngombane xa ubeka iodolo
Ukukhethwa kwezihlanganisi zesitimela samandla kunokubhekisa kwiphepha lama-89 le "Annex"
3. Xa ufaka i-RTD yentambo ezintathu, kuyimfuneko ukuqinisekisa ukuba ezintathu iingcingo zilingana ngobude kangangoko kunokwenzeka
4. Xa ufaka i-RTD eneengcingo ezimbini, kufuneka kufakwe izithintelo zokhuseleko 4 kunye no-2 i-short circuits
