  • Load trending
  • Motor control
  • Fan/Pump Status

Loop powered analog current sensor simplifies installation

    • Power the sensor, and receive the signal with only two wires...lower cabling and commissioning costs than with traditional 3-wire sensors
    • Self-gripping split-core for fast retrofit installation...no need to remove conductor

Selectable factory calibrated ranges for increased flexibility and resolution

  • Factory calibrated switch-selectable ranges for high resolution and installation ease
  • Three field-selectable ranges per unit...fewer versions to choose from, stock, and install
  • Bracket can be installed in three different configurations...added flexibility
  • 100% solid state, no moving parts to fail
  • 5-year limited warranty
