5. Frequently Asked Questions (FAQ)

Q1: What is the maximum static pressure the Yokogawa EJA130A can handle?

A: Depending on the specific configuration code selected, the EJA130A is rated for high static pressures up to 16 MPa, 32 MPa, or 42 MPa, making it ideal for high-pressure industrial lines.

Q2: How do I select the correct diaphragm material for corrosive chemicals?

A: Standard wetted parts are 316L stainless steel. For highly corrosive media (such as strong acids or chlorides), Hastelloy C-276 or Tantalum diaphragms should be selected during ordering.

Q3: Does the EJA130A support HART communication for remote setup?

A: Yes, models equipped with the HART communication option allow seamless digital configuration, device diagnostics, and process variable tracking via standard handheld communicators or asset management software.
