1) Iimpawu zokulinganisa
Ukusebenza komlinganiselo kubhetele kwimitha yokuqukuqela ephathekayo kunye nephathwa ngesandla.Oku kungenxa yokuba amandla azo asebenza ngebhetri, kwaye imitha esisigxina yamkelwa ngumbane we-AC okanye we-DC, nokuba umbane we-DC, usuka kuguqulo lwe-AC ngokubanzi.Ukunikezelwa kwamandla e-AC kunempembelelo ethile kwintsebenzo yokulinganisa, kwimeko yesignali ye-sensor ebuthathaka, umphumo wokulinganisa ungcono kubo.
2) Ukuthelekiswa kokunikezelwa kwamandla
iimitha eziphathwayo neziphathwayo zilungele ukusetyenziswa.Imitha elungisiweyo ifuna i-24VDC yangaphandle okanye i-220VAC AC amandla, iimitha eziphathwayo kunye nezandla eziphathwayo zinamandla ebhetri yangaphakathi, imitha ephathekayo kwiiyure ze-50, imitha ephathwayo yeeyure ze-14.
3) Umlinganiselo wobushushu
imitha esisigxina kunye nephathwayo inokuxhotyiswa ngeperi ye-Pt1000 ukuphumeza umlinganiselo wobushushu, akukho msebenzi wemitha ephathwayo.
4) Iinketho zemveliso
imitha yokuhamba efakwe eludongeni ineenketho ezininzi zemveliso ezifana ne-4-20mA, OCT, Relay, RS485, Datalogger, HART, NB-IOT okanye GPRS;
Imveliso yemitha yokuhamba ephathwayo iyakhethwa kwi-4-20mA, OCT, Relay, RS485, idatalogger, njl.
Ukubamba ngesandla imveliso yemitha yokuqukuqela iyakhethwa kwi-OCT, RS232 kunye neenketho zokugcina idatha.
