Description
Digital, low-frequency safety and control system
PCH 1026 is a highly configurable, digital monitor with a built-in accelerometer. It is designed for low frequency, structural vibration monitoring applications in wind turbines.
PCH 1026 provides far more precise electronic monitoring of the wind turbine than mechanical and electronic detectors. This reduces the turbine downtime and results in a more economical power production.
Designed with the wind industry for the wind industry
The PCH 1026 structural vibration monitor is designed in close collaboration with world-leading wind turbine manufacturers and is currently protecting more than 120,000 wind turbines worldwide.
The monitor is regularly being upgraded with new functionality based on customer feedback and needs.
