| Q |
Does the EJX have the same maximum working pressure (MWP) capability as the EJA? |
| A |
The EJX110A M, H, and V capsules with a standard wetted parts material model are rated to 25 MPa (3600 psi) - an improvement on the EJA specifications, which are currently 16 MPa or (2300 psi). |
|
| Q |
Does the HART HHT need new device descriptions (DDs) to talk to the EJX? |
| A |
Yes - the EJX DDs are new, and they can be downloaded from the Internet. Other communicators are available on the market, but all require the EJX DDs to allow full access to all parameters and features. |
|
| Q |
Can the contact output be used as a level switch? |
| A |
Yes, the EJX contact output can be used simultaneously as a level switch and a transmitter. This dual function is unique within the industry and can eliminate the cost of a second device used for overflow protection.
(Contact rating: 10.5 to 30 V DC, 120 mA DC max.) |
|
| Q |
Is there a permanent stainless steel tag like with the EJA? |
| A |
Just like with the EJA, a permanent stainless steel tag is provided at no additional cost. There is also an optional wired-on stainless steel tag, option code /N4 that can be provided at an additional charge. |
|
| Q |
Are there any changes in face-to-face dimensions as compared to the EJA? |
| A |
No, the face-to-face dimensions are an industry standard (IEC61518) that allows traditional mounted transmitters to be interchangeable from manufacturer to manufacturer. |
|
| Q |
Does the EJX use the same sensor as the EJA? |
| A |
The EJX uses a DPharp (high accuracy resonant pressure) sensor to measure pressure just like the EJA; however, the EJX sensor is manufactured differently to provide a higher accuracy measurement, which now includes the static pressure measurement. |
