EJA118N Differential Pressure Transmitter
Brand: YokogawaThe EJA-A series is Yokogawa's most successful pressure transmitter line. First released in 1991, it continues to offer high performance and high reliability for any application. With an installed base of over 4-1/2 million EJA-A transmitters worldwide, it has a proven track record that makes it a true industry workhorse.
The EJA118 is a Differential Pressure Transmitter with remote diaphragm seals in the series.
It is available with Flush-type seals (EJA118W), Extended-type seals (EJA118N), or a combination of the two (EJA118Y)
