The ES-02 Condensation Monitor is a high-precision anti-condensation sensor designed specifically for chilled beam and radiant cooling systems. It monitors surface relative humidity in real time and triggers early warnings to the BMS before condensation forms, effectively preventing water damage, dripping, and mold growth. Item No.: ES-02 Early Condensation Prevention: Detects rising surface humidity before visible dripping occurs, protecting chilled beams, radiant panels, and ceilings from water damage and mold. High-Precision RH Sensing: Accurate measurement range of 10%–100% RH with premium sensing elements for reliable localized detection. Versatile Dry Contact Relay: Potential-free changeover contact (24V AC/DC, 0.5A) for seamless integration with any controller or BMS. Stable Operation: Built-in 5% RH hysteresis prevents false triggering and system hunting. Flexible Installation: Supports wall mounting or pipe mounting (up to diameter 50mm) with included thermal conductive film for accurate surface temperature reading. Full BMS Integration: Native support for BACnet and Modbus protocols, ideal for smart building automation projects.
