Geosynthetic Transmissivity Tester - China

Scope of application:

It is used to measure the characteristics of the plastic drainage plate in the plane direction of the water flow under the specified pressure.

During the test, seepage was carried out under the condition that the lateral pressure of the sample was 350kPa and the hydraulic gradient i=0.5 - and the water seepage of the sample in a certain period of time was measured.

Instrument features:

Customized pressure gauge with imported high precision diffused silicon pressure sensor and 16-bit high resolution A/D converter; High energy lithium sub-battery is used to power the pressure gauge, and the continuous use time is more than 1.5 years; Pressure gauge can be adjusted to zero with one click, suitable for a variety of environments; "kPa, MPa, Psi, mmHg, Bar, Kgf/cm2" six units can be switched; The open-type hatch door structure is convenient for sample loading.

The body adopts the casting aluminum integrated molding process to ensure the sealing of the pressure chamber; The specially designed sample holding device prevents the deformation of the plastic core plate of the drainage plate, combined with the sealing design, to ensure that the sample holding is air-tight and water-tight; The hydraulic gradient can be adjusted by the height of the water tower.

Reasonable design of waterway pipeline reduces the loss of water head in the test, and the result is more accurate; Pneumatic control element to control the inlet and outlet of compressed air and the size of pressure, to provide side pressure for the test; Pressure chamber and seal plate can be customized according to customer requirements to meet different sizes of samples.

Technical parameters:

Test chamber structure is open The effective length of the sample is 400mm Sample width 100mm can be customized Side pressure 350+20kPa(gauge accuracy 0.4%FS) Head difference adjustment range 0——400mm Accuracy 0.4% Dimensions Host : 715x300x260mm Water tower : 440x440x860mm Weight 35kg
