NOTE:
The measuring output “4-20 mA" is a current drain, this means, the output channel has the same electrical behaviour as
a variable resistor. An active power supply for the measuring circuit is always needed.
For connection to BAMOPHOX TUR, please see specific documentation msa436-01.
Signal in limit conditions:
0 mA = wrong connected and / or dip-switches wrong adjusted
4 mA = 0 FNU (clearest water, pipe filled)
20 mA = 100% output acc. to adjusted range (pipe filled)
22 mA = over range
21 mA = general failure on electronics
When pipe is empty:
If there are no water drops on the glasses the output will be a little bit higher than 4 mA (depending on the
refraction index of air-molecules). If there are water drops on the glasses the output is higher than 4 mA, but the signal depends on size
and quantity of water drops.
So it´s important to install the turbidity measurement system always in such a way that the pipe is filled at any time (ver-
tically or with a siphon). That’s valid not only for TURBICUBE but for all systems on the market.
