Optical Liquid Level Switch (SS316L)

It is necessary for some industrial applications, such as food and beverage processing, pharmaceutical systems and hydraulic reservoirs, to detect the presence or absence of liquid. The optical level switches are ideal for installing in a tank or container where space is restricted. Without the worry of unreliable moving parts, these sensors can provide stable process control for you. Besides, the 316L stainless steel single point level switches can be used in the operating temperature range from -20 to 100°C.
