FTYB-3000BStrain Sensor
The FTYB-3000B digital dynamic-static strain sensor is used to measure the micro-strain generated in a structural body under static load. It is a new type of strain sensor developed using magnetic induction position coding technology; it does not need to connect to a secondary instrument, and directly transmits the measured value digitally to a specially configured digital display or computer. The wired/wireless transmission distance can reach 1km or more.
II. Product Applications:
Dynamic and static strain measurement on the surface of engineering structures (such as concrete and components) and in civil engineering bridges, slabs, columns, etc.
III. Product Advantages:
The strain sensor is used to measure the micro-strain of steel structures or concrete structures. Within a 150mm gauge length, we use all steel materials, whose expansion coefficient is close to that of concrete, ensuring more accurate measurements.
IV. Product Features:
Built-in high-speed digital acquisition and storage chip, with a dynamic frequency response of 0-200 Hz, fully meeting the static and dynamic impact response requirements of large bridge structures. At the same time, it has high sensitivity, good linearity, stable performance, strong anti-interference ability, convenient installation, and is suitable for long-term observation. The wired or wireless transmission distance can reach 1km or more.
V.Working Principle:
Strain is measured by directly measuring the tiny length change within a certain gauge length (e.g., 150mm gauge length) of an object. Therefore, this strain sensor is equivalent to a micro-displacement measuring electronic device (its displacement resolution is 0.015μm, equivalent to an electronic digital indicator). The principle is similar to measuring the length change within the gauge length via a dial indicator.
