 alpha-COND 1000 1/4 DIN Conductivity Controller
Ten Selectable Conductivity Measurement Ranges in one controller via its IP54 front panel. High-level accuracy of ±1% of full scale can be obtained with appropriate cells and correct temperature coefficient User-Customization through Advanced Setup Menu offers flexibility in matching the controller's functions to suit individual's specific requirement Choice of Cell Constant (0.01, 0.1, 1.0, 10.0) for accurate control in any solution Hold Relay for use with float switches/flow switches and other controllers as a failsafe function Two Level Password Protection prevents un authorized tampering with settings 0 to 2000 Second Time Delay Adjustment on control and alarm delays Galvanically Isolated Scalebale 0-20/4-20 mA Outputs Wash Contact Relay controls electrodes cleaning systems at desired duration and frequency Adjustable Hysteresis (Dead Band) prevents rapid contact switching near set point Non-Volatile Memory retains all stored parameters and calibration data even if power fails Line Resistance Compensation against intrinsic cable resistance for longer cable connection Large Dual Display shows measurement with temperature simultaneously - features clear multiple icons, set points, and status messages Choice of Temperature Sensor Pt100/Pt1000 with 2-wire or 3-wire temperature input selection Easy Installation and Wiring with detachable plug-in connectors
Applications:
General: Use for virtually any batch or online applications where rapid, accurate control. Great for OEM/system integrator.
Industrial: Use in applications involving agriculture, chemical processing, boiler and water heaters, wafer-fab, microprocessor manufacturing, pharmaceuticals, pulp and paper industries, and bleach manufacturing.
Water Purification/Treatment: Use to treat batches of incoming process water, ultrapure water, boiler and feed water control.
Regulatory: Hook up to recorder for regulatory compliance data collection.
