A smart device for wind turbine blades
Ping Monitor continuously measures and analyses changes in the sound generated by blade damage.
Sound from wind turbine blades is received by the microphone and processed through different algorithms to identify noise from damage. Then the data is sent to the Ping
Cloud for analysis and blade conditions report.
In cases where a repair is not prioritised, the Ping Monitor will continue to track damage and its progression over time.

Signal with no blade damage:
Signal with blade damage:
A plug and play device easy to install and simple to operate.
The Ping Monitor is self-contained, uses solar power and cellular communication, it doesn’t require connection to either power or data being completely independent from the turbine and with no maintenance needed.
Only one Ping Monitor is necessary per wind turbine tower, rather than instrumenting each blade with multiple sensors.
It attaches magnetically to the base of the tower in less than one minute, with zero installation and replacement costs and once installed, it immediately starts measuring the sound generated by the blades as they rotate.
What can you expect from Ping Monitor?
Optimise inspection processes and reduce maintenance costs
Stop worrying about inspecting every single turbine periodically, we continuously monitor all turbines at the same time. That way you don’t need to inspect towers that aren’t showing damage, optimising inspections and saving on maintenance, downtime and failure risks.
Detect damage earlier
Accurate data means less turbine downtime and improved performance. Understanding the health of your blades and detecting blade defects before they escalate and become costly is critically important, allowing prompt blade repair when the damage is smaller and cheaper to fix.
Continuously know the condition of your wind turbine blades
Data provided by the Ping Monitor is sent to the cloud and it can be reviewed and analysed remotely by operators and stakeholders any time and from any device, as well as get notified as soon as the monitor detects any damage.
Ping Cloud uses a simple and easy to use dashboard which lets you quickly review and analyse results and identify which turbines require maintenance.
User-defined notification criteria can be set so key stakeholders remain informed on any significant blade condition changes.
Types of damage detected
Ping compares the sound that is detected from the blades to known acoustic signatures from damaged blades to identify the likely magnitude and type of damage.
The blade tip and the inflow edge are particularly exposed to erosion, which is detrimental to aerodynamics and significantly diminishes energy yields.
Leading edge erosion
Leading edge erosion is an emerging issue in wind turbine blade reliability, causing performance decreases and additional maintenance costs.
Gouge or lightning strike
Lightning strikes wreak havoc on wind turbine blades, and sometimes these lightning blasts cause severe damage to the blade.
A split tip will weaken the structural integrity of your blades, negatively affect the blade aerodynamics and reduce overall turbine performance.
