DMKY-4 ultra-miniature dynamic and static pore water pressure sensor
Introduction:
DMKY-4 ultra-miniature dynamic and static pore water pressure sensor can be embedded or installed in model experiments, machinery and equipment, soil and rock infiltration water and other small pores to measure infiltration (or pore) water pressure inside structures or foundations and reservoirs , lakes and other water levels, the custom shell can be customized into threads and other structures for easy installation, which has strong applicability. This product can measure both static pore water pressure and dynamic water pressure, and is especially suitable for water pressure measurement under vibration and ultra-small gaps.
Features:
1. Small size
The size of the sensor is small, the disturbance to the undisturbed soil is small, the size and shape can be customized, the size can be customized, the minimum diameter can be 5 mm, the length can be 12 mm; other structural dimensions can be customized
2. Good stability
The stainless steel structure of the shell is waterproof, corrosion-resistant, long-term reliable, and can accurately measure the pore water pressure in the soil
3. Strong anti-interference ability
4. High frequency response, low to zero and high to natural frequency, suitable for telemetry and automated data acquisition
5. When the range is small, it can offset the influence of changes in atmospheric pressure
