Athermal Pressure Sensor (P/N: ALAPS01)

Alxenses’s athermal pressure sensor ALAPS01 is designed to measure pore-water or other fluid pressure. It is used to monitor engineering works such as hydraulic structures, foundations, retaining walls, dams, embankments, excavations, tunnels, etc. The unique characteristic of temperature insensitivity makes the sensor does not affected by temperature shift. That improves the accuracy greatly and makes it very simply in applications.


  • Long-term reliability
  • High accuracy and resolution
  • Wide measuring range
  • Rugged stainless steel construction
  • Temperature insensitive
  • High pressure sensitive
