Repeatability: 0.1% of flowrate (minimum 1 mm/s)
Maximum Power Consumption: 12.5W
Insulation Resistance:
• 100M
Ω
between excitation terminal and
each signal terminal at 500 V DC.
• 100M
Ω
among signal terminals at 500V
DC.
Withstand Voltage :
• 1500 V AC between excitation terminal
and ground terminal for 1minute. (for ex-
proof type).
• 500 V AC between each signal terminal
and ground terminal for 1minute.(for ex-
proof type).
• 1760 V AC between each signal terminal
and each excitation terminal for 1minute.
(for ex-proof type).
• 1000 V AC between excitation terminal
and ground terminal for 1minute.(except
for ex-proof type).
CAUTION
When performing the Voltage Breakdown Test,
Insulation Resistance Test or any unpowered
electrical test, wait 10 seconds after the power supply
is turned off before removing the housing cover. Be
sure to remove the Short Bar at terminal “G”. After
testing, return the Short Bar to its correct position.
Screw tightening torque should be 12kgf
-
cm(0.88ft-
lb)or more, because the G-terminal is thought as a
protective grounding and should conform to the Safety
Requirements.
Safety Requirement Standards:
IEC1010, EN61010

Installation category based on IEC1010: II(See Note)
Pollution level based on IEC1010: 2(See Note)
Note: • The “Installation category“ implies the regulation
for impulse withstand voltage. It is also called
the“Overvoltage category“. “II“ applies to electrical
equipment.
• “Pollution level“describes the degree to which a
solid, liquid or gas which deteriorates dielectric
strength is adhering. “2“ applies to normal indoor
atmosphere.
