Specificity
Results:
Manufacturer and evaluator claim
sensors will respond to any liquid after its threshold is exceeded.
Testing was specifically conducted for performance in water and water with a thin layer of fuel.
Manufacturer’s
Specifications:
Can be installed on any control device that accepts TS232 communication
from the sensor.
Models EOS100 and EOS120 sensors identify liquid in a range from nominal depth of 0.5 inch to 3.5 inches at 0.75 inch increments.
The Model EOS120 sensor is designed to be a drop-in replacement for the Model EOS100 sensor.
Comments:
*The position of the Model EOS80 sensor can be adjusted for any depth of
liquid required.
