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 Technical parameter: Measuring medium: various permeable liquids Range: 0～5KPa…100kpa…1Mpa…10Mpa optional for each range segment Output: 50mV, 0～5V, 0～10V, 4～20mA can be customized Power supply: 1.5mA, 5mA or 15V, 24VDC can be customized Frequency response: 0~100~200~500~1000~2000~1000000HZ optional, up to 1MHZ The state of the tested object: both dynamic and static can be tested Nonlinear: 0.05%FS; 0.15%FS; 0.3%FS; 0.5%FS Hysteresis, repeatability: 0.03%FS; 0.1%FS; 0.2%FS; 0.3%FS Accuracy: 0.1%FS; 0.2%FS; 0.5%FS; 1%FS; Overload pressure: ≥150%FS can be customized Zero temperature coefficient: 0.03%FS/℃ (typical) Sensitivity temperature coefficient: 0.03%FS/℃ (typical) Compensation temperature range: 0～70℃; -25～50℃; 25～125℃; 25～175℃ Storage temperature range: -40℃～125℃ Relative humidity: 0%～100%RH
