Settlement Sensor

  • Model: PT124B-226
  • Pdf:



PT124B-226 series monocrystalline silicon settlement sensor designed with level vessel, high precision chip, circuit modules, safety cover and etc. It is suitable for level measurement with small range and high accuracy; it is the ideal choice for the vertical displacement and tilt monitor for dam, nuclear power station, high-rise building, tunnel, bridge, underground, geological settlement, dangerous building and etc.

Work Principle:

The pressure cavities of settlement sensors series connect level vessel via a tube filled with water. The measurement component is high precision monocrystalline silicon, transfer the process pressure signal to acquisition system. Then calculation and analysis the displacement height of the measurement surface.
