SAKATA's sensors detect changes in the ground such as earth pressure, water pressure, load, inclination, temperature, settlement, horizontal drift, strain and displacement. Sensors developed with advanced technology and long experience provide accurate data.
  Data Logger    
    SAKATA's Data Loggers can be connected to a variety of sensors and acquire data with high precision and long term stability. Also they can be used under harsh condition. We can supply remote control type, DC type, etc.
Wireless Sensor (Underground Wireless Communication System)    
  This system transmit measured data in cable-less and can be used effectively in underground, undersea and air, such as landfill, tunnel and dam. Many of patents are obtained in Japan and in the other 8 countries.   About Wireless Sensor
