Sanitary Photoelectric Level Switch Model: OLS-F1

Sanitary Photoelectric Level Switch Model: OLS-F1

Autoclavable, compact design, no moving parts, easy to change installation position with screw-in type, accuracy ±2 mm.

The OLS-F1 photoelectric level switch is used to monitor liquid level in sanitary applications, and the photoelectric sensor consists of an infrared LED and a light-receiving part. The light from the LED is directed towards a prism that forms the tip of the sensor. As long as the tip is not submerged in liquid, the light reflects within the prism and reaches the light-receiving part. When the liquid rises within the container and surrounds the tip, the light beam is refracted by the liquid, and the receiver detects that the light does not reach or only weakly reaches it, triggering the switching operation in response to this change. The OLS-F1 photoelectric sensor is specially designed for sanitary applications and is suitable for a wide range of uses. In autoclave applications, it can be used at temperatures up to +134 °C. <Product Details> - Autoclavable - Compact design - No moving parts - Easy to install and can be easily changed to the desired mounting position - Accuracy ±2 mm For more details, please refer to the product data sheet.
