◆Optical water level sensor can be used to replace mechanical type float switch with better level control accuracy and durability, main Features including Compact in construction： 

- No mechanical moving parts, high reliability and high precision level control 

- Meet the safety standard requirements 

- RoHS compliant-Easily mounting method with locking nut. 

- Equipped with 350MM cable length.

1.In practical application, taking into consideration of the influence of steam and dirt, the liquid level threshold voltage is set as VT, that is,

if the output voltage of signal end is higher than VT, the liquid level is decided to be lower than the critical liquid level; and if the output voltage of signal end is lower than VT, the liquid level is decided to be higher than the critical liquid level. VT is set between 0.3 and 0.5 V, and the specific value is determined by the generation speed of dirt. 

2. Considering the fluctuation characteristics, if the fluctuation is large and the fluctuation range is more than 1MM, the anti-shake logic

should be added to the program. 

3. In the long-term of using, the surface of the sensor is dirty due to liquid impurities, slight dirt will not affect the performance of the

sensor. If dirt would cover all the surface of sensor, please inform us the particularity in advance, our technical department can optimize

the treatment. 

4. The sensor will be effected when exposed to direct sunlight. Please install it away from direct sunlight
