Magnetostrictive Level Sensor

The Magnetostrictive Level Sensors provide highly accurate and repeatable level readings in a wide variety of liquid level measurement applications. The Magnetostrictive Level Sensors is certified for installation in hazardous areas in the US and Canada by CSA for Class I, Division 2 and Class I, Zone 2 environments. The Magnetostrictive Level Sensors’s flexible stainless steel stem allows for accurate measurements in environments that are not straight-forward.
