OS150 – High Pressure Optical Liquid Level Sensor

Stainless steel and glass optical level sensor features a maxim PSI of 2,500, corrosion resistant, and accurate.

Product Description

This stainless steel, high pressure optical liquid level sensor is designed for applications in high-pressure fluid applications. The OS150 optical is a miniature point level sensor with built-in electronics and work with no moving parts. Optical sensors are an optimal choice if you are looking for non-contact liquid level sensing. This mini optical switch is capable of measurements within 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. The OS150 is ideal for corrosion-resistant level sensing in pressure vessels, refrigeration, and hydraulic applications. The glass to metal seal allows high-pressure liquid level sensing up 250 PSIG. In addition, it can be mounted via a 1/2″NPT port.

The main advantages of optical level sensors are their compact size, lack of moving parts, and their low cost. All while being extremely accurate for point level detection in high-stress environments. As a result of being a no contact and accurate, this sensor is ideal for use in the contamination prevention market, in systems like clean in place (CIP). Unmanned aerial vehicles (UAV) or drones are another ideal application for optical level sensors. Farms and agricultural businesses can use optical sensors on a drone, to spot possible issues in their crops helping to make quick decisions to save the rest of the field. It can also be used for the safe landing of the drone.
