| Wiring
for Meter with Frequency Output Signal |
| |
This meter uses three wires to
transmit frequency output signal to other external equipments,
with power supply 24V ＼10%, the minimum load resistor of output
circuit 10kΩ, the maximum capacitance 0.22μF, and resistance
of shielded wire must be less than 50Ω.
Normally, a three cores shielded wire (RVVP3〜0.5mm) is used
as connecting wire. 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 be used to meet this environment.
Connecting wire should not be parallel to the power cable,
with distance between them more than 15cm at least. Place
them into independent steel tube should be better. Fix connecting
wire and can not be shaken.
