Optical Level Switches
from Intellisense Microelectronics Ltd.
The optical liquid level switch consists of an infrared LED and a receiver. In air, the light beam from the infrared LED is reflected back into the receiver. When rising liquid touches the tip of the sensor, the light is refracted away from the device, causing little light to return to the receiver. [See More]
