Wireless sensing system

Convenience 路 Low Cost 路 Intelligence


We will be the company Which tries our best with the advanced technology. Our company develop and sell the variety of sensor products based on wireless which can be used on site of constructing structure or in the laboratories effectively. Now that the wireless acceleration sensor which is developed and sold currently is easy to use and economical comparing with the existing the wired acceleration system, we are sure that it will be applied to the measurement tests and practice education of schools or laboratories usefully. And it can be also applied to building safety management measurement system or safety inspection or long term monitoring system out of execution of construction sites. Our company promises to realize the products of various future-oriented sensor through further constant technology development based on our motto of development, Smart, Convenience, and Low Cost.

Shaking Table

l For Structural Dynamics Education and Research

Description

The shake Table (ST-ER-1) helps successfully integrate Structural Dynamics & Control, Earthquake Engineering and related fields into Civil Engineering curriculum and research. This portable, bench-scale table is powered by a Ironless linear motor. The load is directly connected to the motor. Therefore, there is no backlash or elasticity from the moving elements. Thus, the dynamic behavior of the servo control is improved and higher levels of accuracy are achieved. The ST-ER-1 is instrumented with an optical encoder and accelerometer. Each ST-ER-1 moves along a single axis, however, two tables can be coupled for dual axis, x - y operation.

Key Features

·Portable, accessible & easy-to-use

·Allows hands-on student involvement, introducing experimentation and research techniques

·Easy integration of your structures, sensors and actuators

·Simple, standalone software operation

·Single (x) or Dual (x-y) axis configurations

·Complete, cost-effective turnkey systems provided

·0.2-20 Hz., 16cm. stroke

·1.5g acceleration with 20kgf payload (ST-E-1)
