CAL-C701 Cost-Effective Submersible Water Level Sensor for Water Tank
Products Description
The CAL-C701 operates on the reliable hydrostatic pressure measurement principle, converting liquid pressure into precise level data via a high-performance piezoresistive sensing element material SS316L. Constructed with stainless steel (default SS304, SS316L optional) of the wetted parts and housing, it delivers exceptional corrosion resistance and structural robustness, ensuring long-term durability in diverse water quality conditions while maintaining cost-effectiveness.
Boasting an IP68 ingress protection rating, the sensor is fully sealed against dust and continuous submersion, making it ideally suited for water level monitoring in storage tanks, water cisterns, and various stationary water-holding vessels. Its design features no moving parts, minimizing mechanical wear and reducing maintenance requirements—key advantages for economical long-term operation.
