Overview

  • Provides 10 to 30V dc supply voltage with two selectable NPN or PNP outputs
  • Offers dual-discrete outputs for setting independent near and far limits for both outputs, for applications requiring high and low-limit sensing
  • Senses extended range of up to 8 m
  • Features ultrasonic dead-zone of only 2.5% of the total range—75% less than comparable product
  • Features a completely sealed, shock-resistant housing ideal for monitoring levels of liquids as well as solids
  • Available in chemically resistant models with a Teflon coating to protect the transducer
  • Compensates for temperature, for greatest sensing accuracy
  • Simplifies setup with push-button and remote TEACH-mode programming
  • Shows status during setup and operation, using highly visible LEDs indicators
