Yokogawa Absolute Pressure Transmitter EJA310 

Introduction

The high performance gauge pressure transmitter model EJA310A can be used to measure liquid, gas,or steam pressure.  It outputs a 4 to 20 mA DC signal corresponding  to the measured absolute pressure.
Model EJA310A also features remote setup and monitoring through communications with the BRAIN™
terminal and CENTUM-CS™ or XL™ or HART® 275 host. 

 

Feature

Functional  specifications

 

1)Zero Adjustment Limits
Zero can be fully elevated or suppressed, within the Lower and Upper Range Limits of the capsule.

 

2)External Zero Adjustment
External zero is continuously adjustable with 0.01 % incremental resolution of span. Span may be
adjusted locally using the digital indicator with range switch.

 

3)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.

 

4)Output
Two wire 4 to 20 mA DC output with digital communications, linear or square root programmable. BRAIN
or HART FSK protocol are superimposed on the 4 to 20 mA signal.

 

5)Failure Alarm
Output status at CPU failure and hardware error;
Up-scale: 110%, 21.6 mA DC or more(standard)
Down-scale: -5%, 3.2 mA DC or less-2.5%, 3.6 mA DC or less (Optional code /F1)
Note: Applicable for Output signal code D and E

 

6) Damping Time Constant (1st order)
The sum of the amplifier and capsule damping time constant must be used for the overall time constant.
Amp damping time constant is adjustable from 0.2 to
 64 seconds.

How to Identify Our Genuine Products and Counterfeit

 

The main differences in the appearance between our genuine Yokogawa EJA transmitters and the counterfeit

Here are the main differences between our genuine Yokogawa EJA transmitters and the counterfeit that has already been found FYI.

1) The color is different in the Liquid Crystal Display (LCD). The trademark [YOKOGAWA] above the LCD is different.

Our genuine products: Light Gray with [YOKOGAWA] trademark above it.

Counterfeit: Dark blue without [YOKOGAWA] trademark above it.
