Mazwi ekuti "thermowell" uye "protection chubhu" anowanzo shandiswa mukuyera tembiricha yeindasitiri uye kutonga. Kunyange zvazvo kushandiswa kwavo kwakafanana, pane zvimwe zvakasiyana pakati pezviviri izvi:

Thermowell:
A thermowell ichubhu yakavharwa-yekupedzisira yakaiswa mumudziyo wekugadzira kana pombi kuchengetedza tembiricha sensor, senge thermocouple kana yekudzivirira tembiricha detector (RTD), kubva kune process fluid. Thermowells inobvumira tembiricha sensors kuti iiswe mukuita uku ichipa chipingamupinyi chinodzivirira sensor kubva mukuora, abrasive, kana yakakwirira-kudzvanywa mamiriro eiyo process fluid. Thermowells akagadzirirwa kupatsanura tembiricha sensor kubva kumamiriro ekuita uku ichibvumira kuyerwa kwekushisa chaiko.

Protective chubhu:
Iyo inodzivirira chubhu, kune rumwe rutivi, ichubhu kana sheath inoshanda zvakafanana kune thermowell. Inoshandiswa kuchengetedza tembiricha sensors kubva kune yakaoma maitiro mamiriro, senge tembiricha yakakwira, corrosive atmospheres kana mabrasives. Dziviriro machubhu anowanzo shandiswa mumashandisirwo uko kuratidzwa kwakananga kwe sensor tembiricha kune mamiriro ekuita kunogona kukonzera kukuvadzwa kwe sensor kana kuverenga kusiri iko kwekushisa.

Kupfupisa, nepo ese ari maviri thermowells uye ekudzivirira machubhu achishandiswa kuchengetedza tembiricha sensors, thermowells anowanzo gadzirwa aine akavharwa magumo uye akaiswa mumidziyo kana pombi, nepo ekudzivirira machubhu anosiyana uye anogona kushandiswa mumhando dzakasiyana dzekushandisa. Yakagadzirirwa kudzivirira tembiricha sensor kubva munzvimbo dzakaoma.
