Conductivity Controller
ECM01 Conductivity Controller
Committed to Process Automation Solutions
The model ECM01 is used for the conductive measurement / control of electrolytic conductivity, resistivity or the TDS value. Conductivity is a function of ion concentration, ionic charge, and ion mobility. Ions in water conduct current when an electrical potential is applied across electrodes immersed in the solution. A controller system consists of a microprocessor-based controller and a conductivity probe.
4 Electrode cells (K=0.01, 0.1, 1.0 and 10.0) can be connected to the device. Temperature serves as the second input variable, measured by a NTC10K/ PT1000 probe. Depending on the measured variable, it is therefore possible to implement specific, automatic temperature compensation.
All adjustments to the current outputs, alarm relays, and calibration of the conductivity and temperature inputs can be made using the controller’s membrane keypad.
