  • Page 4: Safety And Responsibility

    1. Safety and responsibility 1.1 Intended use The 2260 Ultrasonic Level Transmitters are an excellent tool for the level measurement of liquids. Level measurement technology based on the non-contacting ultrasonic principle is especially suited for applications where, for any reason, no physical contact can be established to the surface of the material to be measured.

  • Page 5: Function

    2260 Ultrasonic Level Transmitter. A Total beam angle of 5°-7° at –3 dB as is featured by transducers of transmitters and sensores ensuring a reliable measurement in narrow silos with uneven side walls as well as in process tanks with various protruding objects.

  • Page 6: Identification

    Design and function Instruction for use Minimum measuring distance (X ) (Dead Band) is determined by the design of the unit within which the measurement is not possible (Dead Zone). This distance can be extended by programming in order to avoid disturbing effects of possible disturbing echoes coming from fixed objects.
