Yokogawa EJX118B
Wireless Differential Pressure Transmitter with Remote Diaphragm Seals
Segel diafragma nirkabel digunakan untuk mencegah media proses masuk langsung ke dalam rakitan penginderaan tekanan dari pemancar tekanan dan tekanan diferensial, keduanya dihubungkan ke pemancar menggunakan kapiler yang diisi dengan cairan pengisi.
Pemancar Tekanan Diferensial Tertutup Diafragma Nirkabel EJX118B dan Pemancar Tekanan Pengukur Tertutup Diafragma Nirkabel EJX438B dapat digunakan untuk mengukur aliran cairan, gas, atau uap, serta level cairan, kepadatan, dan tekanan.
EJX118B dan EJX438B tidak hanya mengirimkan variabel proses tetapi juga parameter pengaturan menggunakan sinyal nirkabel. Pemancar beroperasi dengan baterai internal, dan biaya pemasangan dapat dikurangi karena tidak memerlukan kabel keras.
Protokol komunikasi mematuhi spesifikasi protokol ISA100.11a.
