KE-25 Micro Pore Water Pressure Sensor or Transducer Description:

User's Manual(CN) User's Manual(EN)

To necessarily measure the pressure in situ due to the requirements for the measured flow field and placement position, and to reproduce the variation pattern of the pulsating flow field without interfering with the flow field state, there are always strict requirements for the miniaturization of the external dimensions of the sensor. The KE-25 micro pore water pressure sensor and transducer are designed for the above working conditions. This series of products, with ceramic filters and stainless steel structures, adopt micro machined silicon membranes core components and high-precision integrated electronic components, using advanced international miniaturization production and packaging technologies. The sensor chip and circuit board are exquisitely and ingeniously packaged, with small volume, compact structure, light weight, which are sturdy and durable, and have excellent measurement accuracy, reliability, stability, and dynamic and static characteristics. This series of products is particularly suitable for various model tests and on-site applications such as geotechnical simulation, centrifuge simulation, landslide and debris flow experiments, slope experiments, dam monitoring, blasting experiments, etc. They have been widely used in many model tests and on-site application fields such as civil engineering, geomechanics, earthquake monitoring, etc.
