138 K58 for Solids

The 138 K58 design is optimized for bulk solid measurements and is used for continuous, non-contact level measurement in powdery to granular bulk solids. With a measurement range of up to 70m it is unaffected by strong dust generation, filling noise and temperature fluctuations. Antennas are available with dust shield and air purging to ensure maintenance free operations.
  • No moving parts: High Reliability, Maintenance Free.
  • Graphical display.
  • High sensitivity for detection of weak echoes in solid applications.
  • Optional aiming device to compensate for angle of repose of solids.
  • Antennas with optional dust shield, air purging for extremely dusty conditions.
  • Dual chamber construction helps isolation of electronics from gland terminals.
  • Narrow beam angle, Max. Measuring range up to 70 m.
  • Conventional 4-20 mA or HART output options.
  • Level to Volume conversion through HARTMATE configuration software (With 64 points conversion table)
