Yokogawa EJA430A Gauge Pressure Transmitter

Transmitter Specifications:


Two wire 4 to 20 mA DC output with digital communications. 

BRAIN or HART FSK protocol are superimposed on the 4 to 20 mA signal.

Stability :

0.1 % of URL per 60 months

Diaphragm :

Hastelloy C-276  SUS316

SCM435, SUS630, or SUH660

Housing :

Low copper cast-aluminum alloy with polyurethane paint (Munsell 0.6GY3.1/2.0)

Degrees of Protection :


Mounting Position Effect

Rotation in diaphragm plane has no effect. Tilting up to 90° will cause zero shift up to 0.4 kPa {1.6 inH2O} which can be corrected by the zero adjustment.

Power Supply

10.5 to 42 V DC for general use and flameproof type

10.5 to 32 V DC for lightning protector (Optional code /A)

10.5 to 30 V DC for intrinsically safe, Type n,nonincendive, or non-sparking type

Minimum voltage limited at 16.4 V DC for digital communications, BRAIN and HART

Basic Information :

The Yokogawa EJA430A pressure transmitter measures the level, density and pressure of liquids, gases or vapors and converts them into a 4~20mADC current signal output. It is a high quality electronic differential pressure transmitter with a single crystal silicon sensor for flow of liquids, gases or vapors as well as level, density and pressure measurements. The static pressure can be displayed through the built-in display table or the BRAIN protocol or the HART communication protocol. It also features fast response, remote protocol setting, self-diagnostics, and optional high/low pressure alarm status output. The EJA430A can also communicate with the BRAINTM Communicator, YHC4150, CENTUMCSTM, FieldMate, and HART475 for setting up, monitoring, etc..

Main feature:

In addition to ensuring high precision, it also achieves high performance with minimal environmental impact such as static pressure and temperature.

It can extend the high reliability of continuous use.

Small and lightweight. It is free from installation and is free to install.

It adopts microcomputer technology and has complete self-diagnosis function and communication function.

The stability of the key zero point during development improves maintenance efficiency. There is no need to adjust the zero point for 5 consecutive years.
