Real-time automatic measurement of subsidence and uplift! Numerous achievements in various locations such as roads, ground, bridges, railways, and buildings.
The wireless subsidence sensor [Wimos] uses a wireless light-receiving sensor and a rotating laser level to measure subsidence and uplift in real-time. It can be used without specialized knowledge as there are no complicated operations. NETIS Registration KT-180034-VE 【Features】 ■ Communication speed: Measures 5 sensors in 1 second ■ Resolution: 0.1mm ■ Reception width: Wireless light-receiving sensor approximately 100mm, long light-receiving sensor: approximately 300mm ■ Retains wireless communication setting functions with each terminal ■ Graph display function, data can be saved in CSV format ■ Battery or AC power supply ■ Alerts via email or rotating light when management values are exceeded (optional) *For more details, please download the catalog or contact us.

basic information
【Examples of Achievements】 ■Architecture: Monitoring whether the floor slab sinks during jack-up (underpinning method) Effect: Simultaneous measurement of multiple points allows for real-time measurement of the flatness (level) of the floor slab. ■Bridges: Measuring whether the bent sinks during girder installation Effect: Increased safety as workers do not need to enter the area. ■Railways: Monitoring rail fluctuations during liquid injection Effect: Real-time data verification is possible since rails cannot be lowered once raised. ■Roads: Monitoring whether there is any impact on the road above during underpass construction Effect: Measuring the integrity of the road and monitoring the safety of passing vehicles 24/7. *For more details, please download the catalog or contact us.

Detailed information
-
Installation Image A high-precision wireless light sensor is installed at the measurement point, and the settlement and uplift conditions caused by nearby construction work are measured using a rotating laser level. Displacement value data is displayed in real-time on the measurement PC via wireless communication.
-
Long Light Reception Sensor Reception Width: Approximately 300mm Body Dimensions: H430mm × W200mm × D130mm Since the reception width is about three times that of a standard sensor, it can be used to measure larger subsidence and uplift.
-
Wireless light-receiving sensor Receiving width: Approximately 100mm Body dimensions: H168mm × W76mm × D36mm
-
Instantaneous graph Visualizing subsidence and uplift with graphs. By visualizing real-time displacements, it allows for intuitive judgment.
-
Real-time measurement values Displays measurement values and relative values for each sensor. Observation points that exceed the management values will be indicated by a change in the row color.
-
Rotating laser level A laser level that rotates 360°. Horizontal accuracy: ±1.5mm per 30m ±10 seconds Correction type: Wire hang, air damp Automatic correction range: ±11 minutes
-
Measurement PC, Control Unit A rugged PC called "Toughbook" that can be used in harsh field environments. It allows for viewing measurement results and setting management values. With the "Control Unit," 1:N wireless communication is possible. A single control unit can support up to 99 light sensors. By adding controllers, it is possible to connect more than 100 devices.
-
Sensor installation image Since it can be easily installed just by placing it with a jig, the installation is straightforward. (The installation method may vary depending on the site conditions.)
-
Rotating light This is an optional rotating light. An alarm will sound if the set management value exceeds the specified limit.
