แบรนด์ : TOKYO KEISO



  • Wide applications by TDR technology
  • 2-wire loop powered system with less cable and low installation cost
  • A current output is selectable from level, distance, volume or mass
  • From - 50°C to 100°C and from full vacuum to 1.6 MPa
  • No influence from changes in temperature, pressure or density
  • The probe can be cut in short on site to the application
  • Start to measure with a minimum setting after installation
  • Measuring Max. 20 min liquids and 10 min powders
  • Easy mounting on top of tanks
  • No moving parts and less maintenance
  • Display language in English, Japanese or others and easy operation
