I-XDB307-2 & -3 & -4 uchungechunge lwama-pressure transmitters zenzelwe inhloso- yakhelwe ukufakwa esiqandisini, kusetshenziswa ama-ceramic piezoresistive sensing cores agcinwe ezindaweni ezivalekile zethusi. Ngomklamo ohlangene futhi osebenziseka kalula, kanye nenaliti yevalvu eklanywe ngokukhethekile yembobo yokucindezela, lezi zithumeli ziqinisekisa ukusebenza okuhle kakhulu kukagesi nokuzinza kwesikhathi eside. Idizayinelwe ukuhlangabezana nezidingo ezidingekayo zama-compressor esiqandisini, ahambisana namafriji ahlukahlukene. Isetshenziswa kakhulu embonini ye-air conditioning kanye nesiqandisi, i-transmitter inikeza izilinganiso zokucindezela ezinembile nezithembekile.
