The LFS73 Explosion-proof & High-temperature Integrated Air Velocity/Air Volume Transmitteriklanyelwe ukusetshenziswa ezindaweni lapho kukhona amazinga okushisa aphezulu namagesi aqhumayo. Izindawo zayo eziyinhloko zokusebenza zihlanganisa:
Izinhlelo Zokulawulwa Kwamandla: Isetshenziselwa ukuqapha nokulawula ukugeleza komoya ukuze kuthuthukiswe ukusetshenziswa kwamandla.
VAV (Ubuningi Bomoya Oguquguqukayo) kanye Nokulawulwa Kwefeni: Idivayisi isetshenziselwa ukulawula ukugeleza komoya ezinhlelweni ze-HVAC, iqinisekisa ukusebenza kahle ekuphatheni umoya nasekuvunyelweni komoya.
Ukulawulwa Kokungcola Kwemvelo: Isiza ekulinganiseni nasekulawuleni izinga lomoya ezimbonini lapho ukulawulwa kokungcola kubaluleke kakhulu, iqinisekisa ukuhambisana nezindinganiso zemvelo.
Ukulawulwa Kwentuthu Nomlilo: Isetshenziswa ezinhlelweni zokudonsa intuthu, i-LFS73 isiza ukulawula ukugeleza komoya ezinhlelweni zokuvuyela ukuze kube nokuphepha uma kwenzeka umlilo.
Ukuvuyela Kwama-oveni Namabhayela: I-transmitter ifanelekele ukuqinisekisa ukugeleza komoya okufanele ezindaweni ezinamazinga okushisa aphezulu njengama-oveni ezimboni namabhayela, ivimbela ukushisa ngokweqile noma ukuvutha okungaphumeleli kahle.
Lezi zimpawu ziyenza ibe ithuluzi eliguquguqukayo nelibalulekile ezinhlelweni zezimboni eziningi ezinobungozi obukhulu, ezizwelayo emazingeni okushisa.
