Chidule
Chotchinga chachitetezo chosiyana: PHD-12TZ-*11, cholowetsa chizindikiro cha RTD, cholowetsa chimodzi ndi chotulutsa chapawiri.
Chotchinga chodzipatula chachitetezo chingasinthe chizindikiro cholowera cha RTD pamalo oopsa kukhala chizindikiro cha 4-20mA ndikuchitumiza kumalo otetezeka. Derali lili ndi chizindikiro chimodzi cha RTD cholowera ndi DC chotulutsa kawiri.
Chizindikiro chotulutsa cha 4-20mA, chikhoza kukonzedwa mwanzeru. Mtundu weniweni wa RTD ukhoza kukhazikitsidwa ndi kompyuta.
PHD-12TZ-*11, "*" imasonyeza mtundu wa RTD wolowera, chonde gwiritsani ntchito khodi kuti musonyeze.
Chogulitsachi chikufunika magetsi akunja a 20 ~ 35VDC.
Mitundu ya zizindikiro zolowera ndi kuchuluka kwa muyeso
