Automatic frozen soil triaxial system PAT-20

The automatic frozen soil triaxial system PAT-20 is used to evaluate the mechanical properties of frozen soil under different temperatures, pressures, and stress paths. It is widely used in cold-region engineering, frozen soil subgrades, tunnels, and underground engineering construction to determine the strength, deformation, and stability characteristics of frozen soil.

LOAD FRAME
The front panel of the load frame is equipped with an LCD screen, an embedded 16-key keyboard. It has a built-in 4-channel data acquisition unit, which can acquire data from sensors such as pore pressure, load, LVDT, and PT100 temperature sensor. It comes with 4 sets of  LED indicators to indicate the working status.
Shear rate: 0.00001~10 mm/min, stepless speed regulation 
Maximum stroke" 150mm 
Load capacity: 200kN
Load cell: 200kN, accuracy: +/-0.1%F.S 
Pore pressure sensor: 0-3MPa, accuracy: +/-0.1%F.S

FROZEN SOIL TRIAXIAL CELL   
Dual-chamber temperature-controlled triaxial cell, the inner chamber used for loading and the  outer chamber used for temperature control. Adopts liquid heating method, and the temperature is closed-loop controlled in real-time via software. It comes with two sets of temperature  sensors: one for detecting ambient temperature and the other for closed-loop control of sample  temperature.
Sample size: Ø39.1mm*H.80mm, Ø61.8mm*H.125mm, Ø100mm*H.200mm 
Temperature control range: -30~+100℃, accuracy: +/-0.1℃
Temperature sensor: 2 sets
Heating method: Liquid heating method
