Tirohanga
Ka taea e te arai haumaru whakamaarama whakamaarama te whakamaarama me te mahi whakamarumaru ngaru ka taea te wehe me te huri i nga tohu thermocouple (TC) i nga waahi morearea ki nga tohu o naianei 4-20mA, ka whakaputa ki te rohe haumaru. Ko tenei arai haumaru kua hanga-i roto i te kapeneheihana mutunga makariri, ka taea te whirihora. Ka taea te whakarite te awhe tuturu o te thermocouple ma te rorohiko rorohiko. Kei a ia nga mahi o te whakaoho waea pakaru me waho o te awhe whakaoho.
Ko tenei hua e hiahia ana ki te tuku hiko motuhake, me te tuku hiko motuhake, te whakaurunga, me nga pito putanga.
"*" e tohu ana i te momo whakauru o te thermocouple, a ko te tauira motuhake e tohuhia ana e te waehere (tirohia "Momo Tohu Whakauru me te Ripanga Awhe" mo nga taipitopito).
