AS3050/3051 a wall mounted cooling tower controller equipped with a conductivity meter, an optional second conductivity meter and temperature gauge and circuit board with two recorder outputs

Description

The AS3050(wall mounted) and AS3051(panel mounted) cooling tower controllers are universal applicable for automatic monitoring and control of cooling tower plants. The controller is equipped with a conductivity meter optional second conductivity meter and temperature gauge. The measured conductivity values can be automatically compensated for temperature.. Also optional is a circuit board with two recorder outputs (0(4) – 20 mA). By means of an optional recorder card the measured conductivity and temperature can be sent to a recorder (0-20mA or 4-20mA). If the plug-in card with two conductivity meters has been installed, two flush systems can be controlled. Adaptable to user specific requirements by built-in programmable options.
