Thibelo ea polokeho e arohaneng lehlakoreng la ho lemoha: PHD-22HD-2121, tlhahiso le tlhahiso ea analog, tlhahiso e habeli le tlhahiso e habeli.
Thibelo e arohaneng e ka arola le ho fetisetsa lets'oao la 4~20mA kapa lets'oao la DC 4~20 mA le hlahisitsoeng ke transmitter sebakeng se kotsi ho ea sebakeng se sireletsehileng. Ha transmitter e le sistimi ea terata tse peli kapa terata tse tharo, thibelo ea polokeho e fana ka matla bakeng sa transmitter.
