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 any complicated operations or specialized knowledge. 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: Real-time measurement of the flatness (level) of the floor slab as multiple points can be measured simultaneously ■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 chemical injection Effect: Real-time data confirmation 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 vehicles 24/7 *For more details, please download the catalog or contact us.

Detailed information
-
Installation Image A high-precision wireless receiving 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. The displacement value data is displayed in real-time on the measurement PC via wireless communication.
-
Long Light Reception Sensor Receiving Width: Approximately 300mm Body Dimensions: H430mm × W200mm × D130mm Since the receiving width is about three times the normal size, it can be used when you want to measure larger subsidence or uplift.
-
Wireless light sensor Receiving width: Approximately 100mm Body dimensions: H168mm × W76mm × D36mm
-
Instantaneous graph Visualizing subsidence and uplift in a graph. 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 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 ±10 seconds per 30m 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. Up to 99 light sensors can be connected to a single control unit. By adding controllers, it is possible to connect more than 100 units.
-
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.
