Ürün Hakkında

QXA2101 - Condensation monitor - Remote sensor head (fixed cable connection of 1 m), potential-free changeover contact. The QXA2101 is a condensation monitor designed for chilled ceilings or ventilation, air conditioning, and heating plants. It ensures precise measurement of relative humidity close to the dew point and to output a condensation signal via a potential-free AC/DC 1...30 V relay changeover contact. Its pipe mounting with tensioning strap or surface-mounting on walls or ceilings make it ideal for buildings with chilled ceilings or HVAC plants. Key Features Measurement/control capabilities: Records relative humidity close to the dew point (100 % r. h.) and monitors condensation build up Output type: Potential-free changeover contact Accuracy: Switching point on increase in humidity 95 ± 4 % r. h., Switching differential ca. 5 % r. h. Power supply: SELV/PELV AC/DC 24 V ± 20 % Mechanical details: Housing with snap-on cover made of pure white, flame retardant thermoplastics, remote sensor head (fixed cable connection of 1 m), IP 40 per EN 60 529, 0.192 kg Mounting type: Pipe mounting with tensioning strap (pipe diameter 10...100 mm) or surface-mounting on walls or ceilings Special functions: Use as a condensation switch Typical Applications Chilled ceilings Critical points in HVAC plants or buildings (ducts, fans, etc.) Ventilation, air conditioning, and heating plants System Compatibility 3rd party via potential-free AC/DC 1...30 V relay changeover contact
