(Integral Flowmeter)
• Construction: Ex de[ia] IIC T4
: Converter ; Explosion proof
Flowtube ; Increased Safety and
Intrinsically Safety(ia)
Electrode ; Intrinsically Safety(ia)
Um=250VAC 50/60Hz, 250VDC,
Uo=250V*, Io=3.37mA*, Po=0.211W
*Uo and Io are rms value.
• Gas Group and Temperature Class: IIC T4
• Ambient Temperature: –20 to 60
°
C (power supply code 1)
: –20 to 50
°
C (power supply code 2)
• Fluid Temperature: 120
°
C max
• Electrode Circuit: 250 V AC/DC
• Maximum power supply voltage: 250V AC/130V DC
• Grounding: JIS Class C (grounding resistance 10

WARNING
* In case of TIIS Flameproof type, a remote
flowtube is available for combined use with the
AXFA14 only.
WARNING
In case that ambient temperature exceeds 50
°
C,
use heat-resistant cables with maximum
allowable temperature of 70
°
C or above.
(2) Wiring Installation
For the external wiring of flameproof types, use a
flameproof packing adapter approved by Yokogawa
(refer to Figure 8.4.2) or cable wiring using a flame-
proof metal conduit (refer to Figure 8.4.4 and “IN-
STALLATION AND OPERATING PRECAUTIONS
FOR TIIS FLAMEPROOF EQUIPMENT” at the end
of this manual).
