Siemens Condensation Detector | QXA2100 / S55770-T375

This sensor is a condensation detector designed for surface mounting, measuring 83mm in height and 60mm in length. Ideal for monitoring condensation in environments with chilled ceilings and HVAC systems, it operates with a supply voltage of 24V AC/DC. Weighing only 0.126kg, this reliable device features an IP40 rating, making it suitable for various industrial applications.

• Accurately monitors humidity levels near the dew point

• Prevents condensation damage on chilled ceilings

• Functions as a condensation switch for HVAC systems

• Built with a flame-retardant thermoplastic housing

• Supports mounting on surfaces or via tensioning straps

• Quick response time stabilises operations under rising humidity

• Monitor condensation in buildings with HVAC systems

• Used for chilled ceiling to prevent moisture build-up

• Suitable for detection at critical points in air conditioning

• Effective in ventilation systems to mitigate condensation risk

• Ideal for mounting on pipes with diameters from 10mm to 100mm

The device operates by recording relative humidity close to the dew point. It activates the relay before reaching this point, allowing immediate adjustments to the cooling processes to prevent condensation.

It is essential to mount the sensor in the coldest area of the surface it protects. Additionally, applying a thin layer of thermal conductive paste on the mounting surface enhances accuracy and performance.

The sensor displays a maximum response time of 3 minutes when detecting humidity variations from 80% to 99% relative humidity. This quick action helps maintain optimal conditions in sensitive environments.
