• Wide measurement range

​          HD350-A and HD350-B covers different measurement range​

            HD350-A:0.3 - 10 m
            HD350-B:0.15 - 4 m

  • For screen mode can be selected  

Tank Measurement Image

  • Mask function

          Unnecessary signal can be eliminated from the received signal by manually.
          Echo signal from existing structure positioned between sensor and target cause
          Echo interference. Mask function removes these unnecessary echo effectively.


  • Interface

          Three interface methods are prepared for remote operation.

         1) RS-485 (MODBUS protocol)
         2) 4 - 20 mA current output
         3) Contact points (relay output)
