High-performance Gauge Pressure Transmitters
Description of High-performance Gauge Pressure Transmitters:
Diaphragm seal is used to prevent process medium from entering directly into the pressure-sensing assembly of the pressure transmitter. It is connected to the transmitter using capillary filled with fill fluid. Models EJA438W and EJA438N Diaphragm Sealed Gauge Pressure Transmitters can be used to measure liquid, gas or steam pressure. They output a 4 to 20 mA DC signal corresponding to the measured pressure.
The EJA Series is available with BRAIN, HART, FOUNDATION™ fieldbus or PROFIBUS PA communication protocols.
