Process Controllers & Monitors alpha-RES1000
1/4 DIN Resistivity Controller
-
Two Selectable Resistivity
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)
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
-
Two
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.
Water Purification/Treatment:
Suitable for pure, ultrapure, and reagent grade water batches of incoming
process water.
Regulatory: Hook to recorder to
document data for regulatory compliance.
