Abstract
Methods and systems for in-fluid testing of electro optic liquid sensors are provided. The electro optic sensor has a light source and a light detector such that a first power state is applied to the light source to generate a first light for determining whether liquid is present within the electro optic sensor. Based on a determination that liquid is present within the electro optic sensor, a second power state is applied to the light source for generating a second light. The second power state having higher power over a shorter period of time than the first power state. The second light generated from the light source is reflected and the reflected second light is received at the light detector. The reflected second light is compared to a pulse current threshold value to determine whether the electro optic sensor is functioning properly.
