Fossil fuel power generation, particularly coal and gas fired applications, represent a major source of energy for the North
American market. Modern and clean technologies, together with an ample supply of coal and gas, guarantee that this form of power generation will remain an important source for decades to come.
Power plant modernization, upgrades and new installations require a wide range of electrical connectivity and electronics solutions.
Weidmuller’s extensive worldwide experience in the power generation industry enables them to deliver the necessary solutions, engineering and application support.
Fuel storage and material handling applications are typically located in remote areas and often require instrumentation such as level transmitters. Weidmuller provides connectivity systems for these applications that include:
• Surge protection for signal loops to prevent damage from voltage surges due to lightning
• Wireless I/O for control and monitoring of machines and systems without the need for hard wiring over long distances
