Wireless displacement sensor (crack gauge) is a resistive displacement sensor based on mobile Internet of Things transmission. Firstly, it adopts resistance sensor technology, which can accurately measure the small displacement of buildings or structures and monitor deformation in real time; Built in mobile IoT communication module, data transmission is achieved through wireless network

The LRK-SFZ shallow soil displacement meter (hereinafter referred to as the displacement meter) is used to monitor the displacement of shallow soil (1m) and upload the monitoring data to a designated server. The displacement meter is equipped with an 8800mAh lithium-ion battery and solar panel, which can meet the needs of long-term monitoring

The RS485 laser displacement meter is a measurement device that integrates high-precision laser measurement technology and RS485 digital communication interface. Its main characteristics are high measurement accuracy, good stability, strong anti-interference ability, and the use of non-contact measurement methods to ensure that it never wears out. This laser displacement meter is suitable for monitoring the deformation, displacement, settlement, strain, slip, and other aspects of various structures, such as. At the same time, using a reflector can also measure the static water level of rivers, lakes, and reservoirs.
