Level Sensors

Overview

SMD offers a complete portfolio of liquid level sensing technologies under one roof — float switches, optical point sensors, non-invasive capacitive sensors, and ultrasonic level sensors. This lets OEM customers select the ideal sensing principle for their fluid, vessel, and accuracy requirements, from simple point-level alarms to continuous measurement. Standard and fully custom configurations are available in stainless steel, engineered plastics, and custom-molded polymers.
