Iingenelo kunye nokungalungi kwemitha yokuhamba ngesantya esiphezulu se-transit time phakathi kwezo ziphathwayo, eziphathwa ngesandla kunye nezo zifakwe eludongeni?

1) Iimpawu zokulinganisa

Ukusebenza kokulinganisa kungcono kwimitha yokuhambahamba ephathwayo nephathwayo. Oku kungenxa yokuba amandla abo asebenza ngebhetri, kwaye imitha esisigxina yamkelwe yi-AC okanye i-DC power supply, nokuba yi-DC power supply, ngokubanzi isuka ekuguqulweni kwe-AC. Umbane we-AC unempembelelo ethile ekusebenzeni kokulinganisa, kwimeko yesignali ye-sensor ebuthathaka, isiphumo sokulinganisa singcono kubo.

2) Uthelekiso lombane

Iimitha zohlobo eziphathwayo neziphathwayo zilula ukuzisebenzisa. Imitha esisigxina ifuna amandla e-AC angama-24VDC okanye angama-220VAC angaphandle, iimitha eziphathwayo neziphathwayo zinamandla ebhetri yangaphakathi, imitha ephathwayo iiyure ezingama-50, imitha ephathwayo iiyure ezili-14.

3) Ukulinganisa ubushushu

Imitha esisigxina nephathekayo inokuxhotyiswa ngePt1000 ukuze kulinganiswe ubushushu, asilo msebenzi wemitha ephathwayo.

4) Iinketho zokukhupha

Imitha yokuhamba efakwe eludongeni ineendlela ezininzi zokukhupha ezifana ne-4-20mA, i-OCT, iRelay, i-RS485, iDatalogger, i-HART, i-NB-IOT okanye i-GPRS;

Imveliso yemitha yokuhamba ephathwayo ayinyanzelekanga ukuba isebenzise i-4-20mA, i-OCT, i-Relay, i-RS485, i-datalogger, njl.

Imitha yokuhamba ephathwa ngesandla ayinyanzelekanga ukuba ikhutshwe kwiindlela zokugcina idatha ze-OCT, RS232 kunye nookhetho lokugcina idatha.
