HVAC systems use open or closed expansion tanks to manage thermal expansion of chilled water. Temperature differentials across seasons cause significant tank wall condensation, leading to false triggers in optical level switches.
Xingkechuang HVAC-Specific Solution
Shenzhen Xingkechuang Technology Co., Ltd.non-contact capacitive sensors adhere to the external wall of carbon-steel (internally coated) or plastic expansion tanks, avoiding contact with circulating water and preventing scale buildup.
Dew and Fog Interference Filtered
Capacitive detection with intelligent thresholding completely ignores thin condensation layers, droplets, and fog—responding only to actual makeup water level changes. This enhances water tank level detectionreliability in building automation systems.
