   Product Detail


  • 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

Applications
