Due to the limited availability of conventional energy sources and growing environmental concerns, new energy sources are gaining increasing attention worldwide under environmentally friendly and renewable characteristics. The new energy industry involves wind power generation, new energy vehicles, photovoltaic power generation and so on. The development and utilization of renewable energy can obtain significant economic and environmental benefits.
Micro Sensor provides professional monitoring equipment for the stable operation of wind power generation, lithium batteries and other renewable energy industry monitoring scenarios.
➢ Wind Turbines
Wind turbines require a control system to optimize the orientation of the turbine in the wind (yaw control) and adjust the blades' angle (pitch control). The control system is accomplished through a cylinder system based on hydraulic principles. Pressure sensors play an essential role.
In a high-intensity working environment, monitoring equipment on wind turbines has the following challenges:
1. The harsh working environment requires the measurement products to be stable and durable.
2. The sensor needs to be able to withstand temperature changes and resist high vibration.
3. It also should be compatible with hydraulic fluid media.

➢ Pneumatic Conveying System in Lithium Battery
The production of positive and negative electrode materials for lithium batteries requires powder pneumatic conveying. It transports solid powder or granules by gas energy in a sealed pipeline. The pipeline is prone to material blockage when transporting materials with large particles, high viscosity, and poor fluidity.
When the pipeline pressure is abnormal, the pressure transmitters installed in sections on the delivery pipeline can give an alarm in time. Locating abnormal points facilitates timely repair of abnormal material blocking and ensures normal production.
In such a working environment, monitoring equipment is required to meet the following challenges:
1. The product requires sensitive response, accurate measurement, and timely data reporting.
2. Equipment maintenance is inconvenient, so the requirements for product stability are high.
3. Product solutions with complete certification and qualification are required.
Micro Sensor's pressure transmitters, temperature transmitters and flow meters provide professional monitoring solutions for lithium battery pneumatic conveying systems.
