Ultrasonic Level Transmitter

Ultrasonic Level Transmitter

REF: USLT1

The Ultrasonic Level Transmitter provides accurate, reliable level measurement for liquids and slurries. It is a loop powered, ultrasonic transmitter which operates from a 20-38V DC supply, thus enabling the 4-20mA signal produced to be tranmitted over relatively long distances.

  • Simple setting up procedure, save commissioning time
  • Low power consumption gives economical operation
  • Self-diagnosis facility and automatic re-calibration
  • Polypropylene casing for increased chemical resistance
  • Weatherproof to IP68 (2m for 24 hours)
  • The integral moulded flange accepts ANSI, DIN and BS sizes
