Industrial Applications

1. Industrial Wastewater Treatment Plant

This low-sensitivity relay unit is ideal for controlling pumps in industrial wastewater sumps or collection tanks. Its design accommodates liquids with low specific resistance, such as sewage water or chemical effluents, ensuring reliable level detection without issues from impurities or fluctuating conductivity.

Problem Solved

Prevents pump damage from dry running or tank overflow in environments with highly conductive or contaminated water, where standard high-sensitivity sensors might fail or require frequent calibration.
