U-GAGE QT50U DC Series—Analog

Overview

Long-range programmable ultrasonic sensor with dc voltage and analog output

  • Additional model available for use with FlexPower systems
  • Provides 10 to 30V dc supply voltage with selectable 4-20 mA or 0-10V dc analog output
  • Automatically scales the analog output over the width of the programmed sensing window
  • Monitors continuously
  • 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
