Product Overview
The SensorsX SX-LMNB Series is a magnetostrictive level transmitter designed for precise and reliable liquid-level measurement in storage tanks, process vessels, interface applications, and similar industrial systems. A magnetic float follows the liquid surface, while the internal magnetostrictive sensing element determines the float position from the transit time of a torsional return pulse. Rigid, flexible, and corrosion-resistant probe configurations are available, with support for single or dual-position measurement and multiple analog and digital output signals.
