4-20/HART ultrasonic level sensor - industrial and outdoor use


Jan 2012 -- A new ultrasonic level sensor, Gauger420, has been launched by Solid Applied Technologies. This rich-featured equipment features:

  • Interfaces: Analog 4-20 mA, optional HART and USB port.
  • Optional graphic (64x128) display: 50x25mm2, keypad /sunshade.
  • Range up to 8m (26') for liquids(1) and 5m (16') for solids.
  • Resolution and repeatability 1mm (0.04').
  • Accuracy 0.25% of measuring range or 1.5mm (0.06').
  • Reporting distance, level, volume, temperature, operating hours.

 The new sensor is reliable and durable:

  • PVDF sensor, superior in presence of aggressive chemicals.
  • Plastic PC/ABS+UV, blending roughness and rigidity.
  • Rated IP68 (1.8m deep /96 hr), withstanding rain/dust/snow.
  • Operating temperature: -30° to +70°C (-22° to 158°F)

Main advantages of the device:

  • Extremely short 'dead-zone' of 15 cm (6')
  • High process tracking rate of 10m/min (32'/min).
  • Flexible 4-20 / HART representation and error indications.
  • Automated temperature compensation for 2 temperature sensors.
  • A friendly wizard-based setup or USB PC-based cloning.
  • Advanced algorithms combating against:
  •    (-) Noises, temperature variations, unstable targets, gases


  • Liquid targets, solids (grains) and Open Channel Flow (OCF).
  • Storage vessels, process tanks and outdoor piles.
  • Wastewater, water desalination, water treatmnet plants.
  • Petrochemical, chemical, food and agriculture industries.
  • OEM models and kit parts are available to partners.
