The Smart vibrating wire strain gauge (embedment model) is mainly used for measuring internal strain of concrete structures, and the internal stress of the structure can be calculated based on the elastic modulus of the concrete structure. Before concrete pouring, the product is tied to structural steel bars or installed on customized mounting brackets (such as multi-directional strain gauge mounting brackets), and then concrete pouring is carried out. After the concrete reaches the predetermined strength, strain measurement of the structure can be conducted. Due to the product's lightweight structure and high-sensitivity characteristics, it can also be used to observe the shrinkage and creep of the concrete structure when the concrete is in the initial setting stage.

Introduction：
JMZX-215HAT embedded strain gauge is suitable for strain measurement inside various concrete structures and supports long-term monitoring and automated measurement. It is widely used for strain measurement within concrete structures such as bridges, tunnels, dams, underground constructions, test piles, and laboratory models.
Product Features：
1.Designed and manufactured by vibrating string theory, both ends of the steel string are welded and anchored, and the steel string has a built-in tension structure, which is convenient to install, and has no shear requirements for the installation base, and is more reliable to fix. It has the advantages of high sensitivity, high precision and high stability, and is suitable for long-term observation.
2.The VW sensor has a built-in high performance exciter, using pulse excitation mode, has the characteristics of fast test speed, stable and reliable steel string vibration, frequency signal long distance transmission without distortion, strong anti-interference ability.
3.Strain gauge stainless steel fully sealed structure, good structural performance, waterproof and durable, water resistance depth of 150 meters.
4.Equipped with the company's comprehensive tester can directly display the physical quantity value, but also can display the vibration string frequency (Hz), the measurement is intuitive, simple and fast. With the company's automatic comprehensive acquisition system can achieve unmanned automatic measurement.
5.The built-in temperature sensor of the strain gauge can directly measure the temperature of the measuring point (temperature type), and testing personnel can temperature correct the strain value.
JMZX-215 Embedded Concrete Strain Gage is used in measuring the strain of various concrete structures, including bridges, tunnels, hydroelectric dams, underground structures, piles and laboratory models. The stain gage is tied on the rebar (or special supports) with ligation steel wires or nylon buckles and pouring together with the target structure for installation, automatic and long term monitoring can be achieved.
