 Yokogawa Flange Mount EJA220Ated Differential Pressure Transmitters


High performance flange-mounted differential pressure transmitters EJA210A and EJA220A can be used

 to measure the liquid level and density of crystalline or precipitating liquids, which are then converted into

 current signal output of 4-20ma DC.EJA series support BRAIN, HART and FOUNDATION ™ fieldbus 

PROFIBUS PA or communication protocol.

Product Advantage:

1. Super measuring performance for pressure, differential pressure, liquid level and flow measurement

2. Miniature (2.4kg) all stainless steel flange, easy to install

3. Process connection is compatible with other products to achieve optimal measurement

4. Adopt H alloy sheath sensor (patented technology), high quality cold and heat stability

5. Intelligent transmitter with 16-bit computer

6. Standard 4-20ma with HART protocol based digital signal, remote control

7. Support the upgrading of fieldbus and field control based technologies

Standard specification :
