Submersible Sensor 
and Cable
The LVF-200-R Series optic sensor 
creates a pulsed beam of infrared 
light which is reflected on the oblique 
flat sensor tip. If the tip is dry, the 
light beam is recognized and if it is 
wet, the beam reflects back into the 
liquid. The optic sensor is factory 
calibrated for use with clear or 
translucent liquids. The shape and 
optic characteristics of the oblique 
flat optical surface provides a high 
level of optical efficiency, including 
resistance to ambient light and 
process condensation. The sensor 
offers very broad liquid compatibility, 
it is not recommended for use with 
coating or highly specular liquids. 
Ideal for leak detection.
