Compact level switches | Choosing the right level switch
The operation of an electro-optical level switch is based on an infrared LED and a photoreceptor. The light from the LED is sent to a glass prism forming a tip that constitutes the sensor probe. As long as this prism is surrounded by gas, the light is reflected from the prism to the receiver. When the liquid level reaches the prism, the light beam is refracted into the liquid and the receiver registers a decrease in the received light intensity, which triggers the...
