SMD Sensors is no longer offering the OS150 optical sensor for sale online. We have launched a series of new optical sensors on our float switch focused site fluidswitch.com. The OS4 Industrial Glass Optical Switch can be effective in similar applications and offers a number of similar features as the OS150.

Please visit the OS4 page for more information. 

The OS150 stainless steel optical level sensor is designed for high-pressure liquid level sensing and is capable of measure with 1/16" accuracy. Built-in optical electronics provide a switched output level sensor that can sense the presence or absence of fluids in temperatures up to 125°C.

This sensor is ideal for corrosion-resistant level sensing or in pressure vessels, refrigeration, and hydraulic applications. The glass to metal seal allows high-pressure liquid level sensing up 2500 PSI and can be mounted via 1/2"NPT port.

Our optical level sensors can be custom designed or configured to meet your specific application needs.
