*12 When SUS304 bolt/nut is selected, max. working pressure rating is 23 MPa (230 kgf/cm
*34 “PED conformity” is not applicable for the combination with FM, CSA or NEPSI approvals.
*38 Either one of “digital output - code D5” or “HART communication - code D7” can be selected at a time.
SCS14A (Equivalent SUS316) or SUSF316
The output current value ranges from 3.0 to 3.8 mA for the lower limit and from 20.8 to 21.8 mA for the upper limit.
In case “For oxygen or chlorine (Fluorine oil) service” is used, “oil free finish - code K” must be selected.
Intrinsically safe for NEPSI cannot be selected with -D7.
