Siemens QFA3160D Outdoor Humidity and Temperature Sensor – 0–10 V DC Outputs, Integrated LCD Display

General
The Siemens QFA3160D is a combined relative humidity and temperature sensor designed for measuring outdoor air and room environmental conditions. It provides separate active 0–10 V DC output signals for humidity and temperature, allowing integration with building management systems (BMS), HVAC controllers and other compatible control equipment.

The sensor features an integrated LCD display for local measurement reading. Its humidity measuring range is 0–100% RH, while the temperature measuring range can be selected from three ranges to suit the application.
