alpha CON190 with improved user interface enables user to gain direct access to calibration mode with CAL key and allows quick set point adjustment with SP1 and SP2 keys

  • Quick Set Point Adjustment - SP1 and SP2 keys allow user to adjust set points easily

  • Direct Access to CAL Mode - enables user to enter calibration mode with a simple key press

  • User-Customisation with scrolling, 14-Segment LED - intuitive user interface guides user easily through setup functions

  • Multi Measurement Range- User Selectable

  • Galvanically Isolated 4-20 mA Output for remote monitoring or hardcopy recording

  • Universal Power Supply Input from 85 to 250 VAC/DC allows use at multiple sites and withstands voltage fluctuations

  • Automatic Temperature Compensation with 3-wire Pt 100 system ensures accurate readings under fluctuating temperatures

  • Adjustable Temperature Coefficient (0 to 5.0%/oC) and selectable cell constants for more accurate measurements

  • 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

  • Easy Installation and Wiring with detachable plug-in connectors
