144LD  Intelligent Buoyancy Transmitter with Torque Tube for Liquid Level, Interface and Density
  • Communication HART, PROFIBUS or FOUNDATION Fieldbus
  • Conventional operation with local keys
  • Easy adaptation to the measuring point without calibration at the workshop
  • Backdocumentation of measuring point
  • Continuous self-diagnostics
  • Configurable safety value
  • Software lock for local keys and reconfiguration
  • Simulation of analog output for loop-check
  • Local display in %, mA or physical units
  • Signal noise suppression by Smart Smoothing
  • Linear or customized characteristic
  • Process temperature from
    –196 °C to +400 °C
    (–321 °F to +752 °F)
  • Materials for use with aggressive media
  • Approved for SIL applications
  • Micro sintermetal sensor technology
  • Separate mounting of sensor and amplifier with remote amplifier mounting kit

These intelligent transmitters are designed to  measure liquid level, interface or density of liquids. The measurement is based on the Archimedes buoyancy principle. 
   Easy remote configuration and supervision with PC or Universal Handterminal. The devices also can be operated conventionally using the local keys. Total I/A Series measurement integration is possible through HART,  PROFIBUS or FOUNDATION fieldbus communication.
   The transmitters are approved for use in hazardous areas and SIL applications.
