Note 1: The unit of MWP (Max. working pressure) on the data plate of a housing is same unit as
specified by option code “D1, D3 and D4.”
Note 2: This item cannot be applied to Model EJA118W wetted parts material code H (Hastelloy C), T
(Tantalum), or U (Titanium). (In case for code H, T or U, serration work on the flange gasket
surface is not possible).
Note 3: Teflon film can only be specified for model EJA118W.
Note 4: Specify the process operating temperature for zero correction.
Example: Zero correction by process temperature 90
°
C.
Note 5: The hardware error indicates faulty amplifier or capsule. Standard output status (without /C1) is
up-scale of 110%, 21.6 mA DC or more.
Note 6: Applicable only for electrical connection code ‘2’, ‘3’ or ‘4’. Not applicable for optional code P
ᮀ
and X1. Not applicable for optional code JF1 and JS1.
