This optical level sensor from Sensata Cynergy3 measures the volume of liquid in a container. The single-point level switch activates when the volume of liquid reaches a predetermined level, notifying you when a valve needs to be opened or closed. The sensor's infrared emitter converts an electrical signal into a focused beam of light so it can detect the absence or presence of a liquid at the specified point. You'll commonly find this type of sensor used in hydroelectric power plants and beverage manufacturing.

• Tough polysulfone (PSU) body material for stability in turbulent liquids
• Wide operating temperature range of -25ºC to +80ºC for use with hot or cold liquids
• Internal mounting with M10 threaded terminal to ensure a secure connection

This sensor is highly reliable thanks to the infrared emitter's physical contact with liquid levels, which ensures accurate sensing. The concentration of the infrared beam also makes it resistant to false triggering caused by foaming.

Yes, you can use this level sensor in high-pressure systems with a maximum pressure of 20 bar.
