Product Description
Foxboro LZSA-1000-3 Level Transmitter
Product Overview
- The Foxboro LZSA-1000-3 is a Level Transmitter designed by Foxboro (now part of Schneider Electric) for use in industrial process control systems. This transmitter is used to measure liquid level, interface level, or density in tanks or vessels by detecting the buoyant force on a displacer element. It is commonly employed in industries such as oil and gas, chemical processing, power generation, and water treatment for applications requiring precise level measurement in liquids, including corrosive or high-temperature fluids. The LZSA-1000-3 is part of Foxboro’s displacer-type level transmitter series, known for its reliability and robust construction in demanding environments.
