Rtd sensor for HVAC application and transformer winding

A. Product Overview

The RTD Sensor for HVAC application and transformer winding is used to measure temperature accurately in heating, ventilation, air conditioning systems, and transformer winding applications. It is built with a Pt100 simplex sensing element, which is widely used in industrial temperature measurement because of its accuracy, stability, and long service life.

In transformer applications, this RTD sensor helps monitor winding temperature so that overheating, insulation damage, and equipment failure can be avoided. In HVAC systems, it helps measure and control air temperature, duct temperature, coil temperature, and system operating temperature.

This sensor is suitable for applications where stable temperature feedback is required for monitoring, control, alarm, or protection systems. With Teflon wire insulation, Class B accuracy, and a temperature range of -50 to 180°C, it is a practical solution for industrial and commercial temperature monitoring.

B. Working Principle

An RTD sensor works on the resistance temperature principle. The Pt100 element inside the sensor changes its electrical resistance according to temperature.

At 0°C, a Pt100 RTD has a resistance of 100 ohms. As the temperature increases, the resistance also increases in a predictable and stable way. The connected temperature indicator, controller, transmitter, or monitoring system reads this resistance change and converts it into a temperature value.

In HVAC applications, the sensor provides temperature feedback to the control system for proper heating, cooling, and air handling performance. In transformer winding applications, the sensor helps detect temperature rise inside or near the winding area, allowing the protection system to monitor thermal conditions and prevent overheating.

C. Why It Is Used

This RTD sensor is used because accurate temperature monitoring is important for both HVAC systems and transformer winding protection. In HVAC systems, improper temperature measurement can affect cooling performance, energy consumption, comfort level, and process stability. In transformers, excessive winding temperature can damage insulation, reduce transformer life, and create safety risks.

The sensor is used for:

Accurate HVAC temperature monitoring.

Transformer winding temperature measurement.

Overheating protection in electrical equipment.

Temperature feedback for controllers and indicators.

Continuous temperature monitoring in industrial systems.

Reliable performance in dusty, humid, and demanding environments.

Better system safety, efficiency, and preventive maintenance.

Because the sensor uses a Pt100 element, it gives stable and repeatable readings compared to many basic temperature sensing options. The Teflon insulated wire also makes it suitable for applications where heat resistance and electrical insulation are important.
