The DOS-31 controls and supplies :
- 2 pumps independent one of the other. Pumps operation is settable
3 times a day maximum and 255min maximum for each setting.
- 1 purge, engagement by pulses number on flow entry. Purge
time is set up in seconds. An output contact 3A/230V is accessible
on the terminal block.
Alternative display makes possible to see directly the day and
hour as well as both pumps and purge setting. Two internal batteries
permit to save in case of power out.
Correct operation of each output can be tested apart from cycles
setting. An internal push rod permits top-meter simulation. Operation
setting of both pumps can be easily stopped in mode “STOP”.
This version has an integrated conductivity controller « C2004 »,
0-2000µS range, 4digits display, and settable threshold.
CONDUCTIVIMETRE :
The microprocessor conductivity controller « C-2004-E »
has been developed for qualitative control of water in industrial
environment.
An adjustable threshold on 8 positions by a contact allows connection
of regulation elements or monitoring of measurement (pumps, alarm
…) A buzzer (possibility to put it out of work using a switch)
allows having an alarm in case of release of the threshold. With
its simple design, the C-2004-E permits to get a reliable and
reproducible measurement.
Calibration on this installation is rapid and simple with all
different calibration resistances. |
