HVAC Duct RTD Temperature Sensor

An HVAC duct RTD temperature sensor is designed to accurately measure air temperature inside HVAC ducts, ventilation systems, and air handling units (AHU). These sensors typically use high-precision PT100 or PT1000 platinum sensing elements, ensuring stable and reliable temperature measurement for building climate control and industrial ventilation systems.

In HVAC applications, maintaining proper air temperature is critical for energy efficiency, comfort, and system performance. A duct-mounted RTD sensor is installed directly into the airflow of the duct to continuously monitor temperature and provide real-time data to building automation systems (BAS) or temperature controllers. This helps optimize heating, cooling, and ventilation operations in commercial buildings, hospitals, factories, and data centers.

The sensor generally features a durable ABS plastic housing that protects internal wiring and ensures long-term operation in demanding environments. With a typical temperature range of -50°C to +150°C, these sensors are suitable for most HVAC and air monitoring applications. The stainless steel probe, usually available in 6 mm or 8 mm diameter, allows fast thermal response and easy installation into ducts.

For industrial reliability, HVAC duct RTD sensors often meet IP65 protection standards, making them resistant to dust and moisture. High accuracy, typically Class A as per IEC 60751, ensures precise temperature monitoring for better system control.
