Mā te ārai haumaru motuhake tāuru anaro me te mahi tiaki ngaru e whakarato ana i te pūtake hiko motuhake mō ngā tuku waea e rua - me te toru i ngā wāhi morearea. Ka tukuna te tohu 4-20mA i hangaia e te tuku, e te pūtake iahiko rānei mai i te wāhi morearea ki te putanga o te wāhi haumaru, ā, mā reira ka peia te kawenga i roto i te wāhi haumaru. Mō ngā tuku waea e rua - e toru, mō ngā tohu pūtake iahiko rānei, ka tautokohia e tēnei ārai haumaru te whakawhitiwhitinga ā-rua o te tohu matihiko Hart e whakatakotoria ana ki runga i te tohu 4-20mA, ā, he mahi whakaoho whati waea.
Me whai pūtake hiko motuhake tēnei hua, me ngā pūtake hiko motuhake, ngā pūwāhi tāuru, me ngā pūwāhi whakaputa.
