Working Principle and Design Advantages
The Nexisense YD-223WA2 Series Wireless Seepage Pressure Gauge is based on diffused silicon sensor technology. When the measured medium pressure acts on the 316L stainless steel pressure diaphragm, the sensor converts the pressure signal into an electrical signal. After processing by the internal high-precision circuit, it is wirelessly transmitted to the monitoring platform through the built-in antenna using TCP or UDP protocol.
The core advantages of the product include:
-
Wireless transmission design: Supports TCP/UDP protocol, no complicated wiring required, especially suitable for long-term burial scenarios such as dams and embankments where wiring is difficult.
-
Large capacity low power supply: 3.6V 9900mAh lithium battery combined with ultra-low power LCD display enables long-term unattended monitoring.
-
Rugged and durable structure: Stainless steel 316L sensor, suitable for fresh water and compatible media environments, with excellent corrosion resistance.
-
Flexible customization capability: Range, accuracy, cable length, temperature range and diaphragm material can all be customized according to specific project requirements.
These designs make the YD-223WA2 series an ideal choice for pore water pressure and uplift pressure monitoring in hydraulic and hydropower engineering.
Typical Application Scenarios
Nexisense YD-223WA2 Series Wireless Seepage Pressure Gauge is widely used in the following engineering fields:
-
Hydraulic and hydropower dam and embankment monitoring: Real-time monitoring of dam seepage pressure, uplift pressure and seepage conditions, providing key data for dam safety assessment and risk early warning.
-
Geotechnical and foundation engineering: Long-term monitoring of pore water pressure in boreholes to assess foundation stability and seepage status.
-
Transportation infrastructure engineering: Seepage pressure monitoring of highway and railway subgrades and tunnels to ensure subgrade safety.
-
Pipeline and pressure vessel monitoring: Long-term wireless monitoring of internal pressure in water supply, drainage and industrial pipelines.
-
Smart water conservancy IoT system: As an edge monitoring node, it accesses SCADA or cloud platforms through TCP/UDP protocol to achieve remote data acquisition, centralized management and abnormal alarm.
This series of products is particularly suitable for scenarios that require long-term burial, wireless data transmission and low maintenance frequency, which can significantly reduce on-site wiring difficulty and later operation and maintenance costs.
Selection and Integration Precautions
When selecting for engineering projects, it is recommended to focus on the following aspects:
-
Select the appropriate range according to the maximum possible pressure value of the project. It is recommended that the working pressure be in the 40%~80% range of the measuring range to obtain the best accuracy and service life.
-
For key monitoring points with high precision requirements, 0.1% or 0.25% high-precision versions can be customized.
-
For extreme temperature environments, high or low temperature customized models should be selected, and the battery working performance at that temperature should be confirmed.
-
Wireless transmission distance and on-site occlusion. If necessary, repeaters can be added or higher gain antenna solutions can be selected.
-
During integration, it is recommended to prioritize TCP protocol for stable and reliable data transmission. UDP protocol is suitable for scenarios with high real-time requirements.
