Wholesale Automatic Microcomputer-Based Pneumatic Consolidation Tester (Loess Collapsibility) Manufacturers, Supplier

This fully automatic pneumatic consolidation tester is used to measure the compressive properties of soil under varying loads and confined conditions. The system consists of a pneumatic consolidation tester, a pneumatic pressure controller, a multi-channel communication converter, and a data acquisition system.

Product Description

Product Description

The soil Consolidation Test Apparatus is designed to perform both normal slow consolidation tests and rapid consolidation tests, effectively determining initial consolidation pressure and consolidation coefficients.

New Features: Measuring collapsibility coefficient, deadweight collapsibility, leaching deformation, and initial collapsibility pressure of loess.

Equipment Features

Allows arbitrary programming of rebound modulus, time periods, and pressure ranges for both loading and unloading cycles.

Integrated voice prompts and display guidance for water injection, timing, and formatting during tests.

Pneumatic pressure control ensures stable, reliable, and low-noise operation with separate control units.

Frequently Asked Questions

1. What types of tests can this apparatus perform?
The apparatus can perform normal slow consolidation tests, rapid consolidation tests, and specialized loess tests including collapsibility and leaching deformation coefficients.
2. What is the difference between the YXN-2 and YXN-3 models?
The primary difference is the maximum load capacity. YXN-2 handles up to 4.8 kN (Medium-Pressure), while YXN-3 handles up to 9.6 kN (High-Pressure).
3. How many soil samples can the software manage?
The system is highly scalable, allowing a single computer to collect and process data from up to 32 soil samples simultaneously.
4. Does the equipment support automatic report generation?
Yes, the host computer software automatically records, stores, and processes data to generate professional graphs and export standardized reports.
5. What are the accuracy specifications for deformation sensing?
Depending on your requirements, you can choose between a Water Conservancy standard sensor (0.005mm accuracy) or a National Standard sensor (0.01mm accuracy).
6. Is the pressure control system noisy?
No, the equipment features a stable pneumatic pressure control system designed specifically for low-noise operation in laboratory environments.
