DMTY Mini Soil Pressure Cell (Earth Pressure Sensor)
Product Introduction
The DMTY Micro Soil Pressure Cell is a high-precision strain-gauge based earth pressure sensor designed for geotechnical model testing. It is widely used to measure stress distribution in soil, sand, slurry, mud, and model pile systems, both internally and around structures.
The DMTY soil pressure cell provides accurate monitoring of soil stress variation, making it an essential instrument in geotechnical engineering research, laboratory modeling, and structural interaction analysis.
With compact size options down to 10 mm diameter customization, it is suitable for fine-scale experimental environments where space and accuracy are critical.

Key Features
• High-precision strain full-bridge soil pressure measurement
• Suitable for static and dynamic soil stress testing
• Excellent temperature compensation for stable readings
• Miniature design with customizable diameter (down to 10 mm)
• High sensitivity and low signal drift
• Side outlet or bottom outlet cable options
• Strong anti-interference and long-term stability
• Compatible with DMYB dynamic & static strain acquisition system
• Customizable range and dimensions available

Working Principle
The DMTY soil pressure cell operates based on a full Wheatstone strain bridge principle:
• External soil pressure acts on the sensing diaphragm.
• The diaphragm deforms under load.
• Strain gauges bonded inside the diaphragm detect micro-deformation.
• The full bridge circuit converts deformation into an electrical signal.
• The strain signal is collected and processed by a data acquisition system.
• Final output represents real-time soil pressure values.
This ensures high sensitivity and accurate measurement of soil stress changes in geotechnical experiments.
