LD302 Fieldbus Pressure Transmitter

  • The LD302 is part of first generation of Fieldbus 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 LD302 enables the choice of several types of transfer functions, and easy interface between the field and the control room. Also it has several interesting features that will considerably reduce the installation, operation and maintenance costs.
