The OS6 glass tip phototransistor optical sensor (POS) is robust and rugged, ideal for harsh industrial environments, aggressive chemicals and extreme temperatures up to 140°C. The sensor can detect the presence or absence of almost any oil or water based liquid. N and P type outputs can sink or source up to 200mA at a supply voltage range up to 30Vdc and can be configured to be a high or low signal in either a wet or dry state. The stainless steel body combined with a crystal glass sensing tip allows the POS Glass Tip range of liquid level switches to operate under high pressure conditions up to 1160 psi. An LED is provided for switching indication.

This optical level sensor is extremely accurate for point level detection, designed for high-stress environments. Optical liquid sensors operate accurately in any size tank, and are designed with a very robust construction permitting use in a wide variety of demanding applications. As a result optical sensors are a go-to option for leak detection. The monitoring and prevention of leaks is critical for service interruptions, to protect equipment and is critical to many industries. Optical sensors can be mounted inside or outside of any tank, ideal for industrial applications because they are compatible with most fluids and chemicals.
