| Wiring
for RS-485 Communication |
| |
Four wires transmission is applied
between vortex flowmeter with RS-485 output and other equipments.
Power supply is 24V DC ＼10%.
Normally, 600V PVC insulated wire or cable should be used
as connecting wire. The two cores shielded wire (RVVP2〜0.5mm)
should be used where electrical noise occurs likely. The outer
shielded layer should be connected to the grounding screw
in amplifier box reliably. Appropriate shielded wire should
be used to meet field temperature when meter used in high
or low temperature ambient.
When the atmosphere surrounded the field contains oil, solvent
or other corrosive gas and liquid, appropriate shielded wire
should meet this environment. |
