Ukubuka konke
Isithiyo sokuphepha sokufakwa kwe-RTD singaguqula izimpawu ezimbili ze-wire noma ezintathu ze-thermistor (RTD) ezindaweni eziyingozi zibe izimpawu zamanje ze-4-20mA bese sizikhipha endaweni yokuphepha. Singalungiswa ngobuhlakani, futhi ububanzi bangempela bokumelana nokushisa bungabekwa ngesofthiwe yekhompyutha. Sinemisebenzi ye-alamu yokuphuka kwentambo kanye ne-alamu engaphandle kwebanga.
Lo mkhiqizo udinga ukunikezwa kwamandla okuzimele, okuneziphesheli zamandla ezihlukanisiwe, okokufaka, kanye nokukhipha.
"*" imele uhlobo lokufaka lwe-thermistor, futhi imodeli ethile imelelwe ikhodi (bheka "Uhlobo Lwesignali Yokufaka kanye Nethebula Lobubanzi" ukuthola imininingwane).
Izinhlobo zesignali yokufaka kanye nobubanzi bokulinganisa
| Ikhodi | Imodeli ye-RTD | Ububanzi bokulinganisa | Ibanga elincane | Ukunemba 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% |
Isibonelo: Ukufakwa kwesithiyo sokuphepha esihlukanisiwe i-Pt100, ibanga lokushisa elingu-0~400℃, imiphumela emibili ine-4~20mA, ukunikezwa kwamandla kungu-20~35VDC. Imodeli iyi-PHD-22TZ-4141(0~400℃), ibanga lokulinganisa lingasethwa kububanzi obucacisiwe obungu-0~400℃ yikhompyutha.
* Ukunikezwa kukagesi esiteshini samabhasi, sicela ubheke isithasiselo ukuthola imininingwane.
| Imininingwane | |
| Faka ngaphakathikuyingoziindawo | |
| Isignali yokufaka | Izimpawu ezimbili ze-thermistor yezintambo noma ezintathu (bheka "Uhlobo Lwesignali Yokufaka kanye Nethebula Lobubanzi" ukuthola imininingwane) |
| Ukunqanyulwa kokufaka | "I-alamu ephansi" ezenzakalelayo ingashintshwa ibe "i-alamu ephezulu" ngesofthiwe yokucushwa |
| Ibanga lesiginali | Ububanzi bokulinganisa obuhambisanayo bokumelana nokushisa |
| Ububanzi bokulinganisa | Abasebenzisi benza ukucushwa kwabo lapho be-oda, futhi bakubonise ngenombolo yomsila noma ngenye indlela. |
| Umphumela ohlangothini lokuphepha: | |
| Isignali yokuphuma | 4~20mA |
| Umthamo womthwalo wokukhipha | 0~500Ω (okungenziwa ngezifiso) Uhlobo lokukhipha i-voltage olukhethwayo, ukumelana nomthwalo RL ≥ 330kΩ |
| I-Voltage Yokunikezela | 20-35VDC |
| Ukusetshenziswa kwamandla | ≤ 90mA (uma ugesi ongu-24VDC, Ukukhishwa okungu-20mA) |
