DMTY strain earth pressure sensor
- PRODUCT DETAIL
DMTY strain earth pressure sensor
Introduction:
This product is used in underground structure tests that can be embedded in different foundations and tunnel slope media to measure the pressure distribution values in different internal measurement areas. It can also be used to test the lateral pressure of reinforced concrete (beams, plates, columns, etc.) templates use. It is a high-precision contact stress sensor, suitable for stress measurement in field tests. It has high output sensitivity, good linearity, repeatability and stability, good water resistance, light weight, easy installation and use, reusable and cost-effective, and can be used for static and dynamic testing.
