LD303 Profibus Pressure Transmitter

  • The LD303 is from the first generation of Profibus-PA devices. It is a transmitter for differential,
    absolute and gauge pressure, level and flow measurements.
  • It is based on a field-proven capacitive sensor that provides reliable operation and high performance.
  • The digital technology used in the LD303 enables the choice of several types of transfer functions, an easy interface between the field and the control room and several interesting features that considerably reduce the installation, operation and maintenance costs.
