Honeywell RSPT1000 Duct Mount Temperature Sensor

A. Product Overview

The Honeywell RSPT1000 is a duct-mounted temperature sensor used for reliable temperature measurement inside air ducts. It comes with a Pt1000 sensing element, which provides stable resistance-based temperature measurement for HVAC and ventilation systems.

This sensor is designed for duct installation and is commonly used in air handling units, ventilation ducts, air conditioning systems and building management systems. It helps monitor air temperature in discharge ducts, return ducts and outside air ducts.

The sensor has an IP54 protection standard for the terminal box and tube, making it suitable for HVAC environments where dust and light moisture protection are required. The terminal box is made from flame-retardant plastic material and is designed for safe and durable installation.

B. Working Principle

The Honeywell RSPT1000 works on the principle of resistance temperature detection using a Pt1000 sensing element.

A Pt1000 sensor has a nominal resistance value of 1000 ohms at 0°C. As the temperature changes, the resistance of the Pt1000 element also changes. The connected controller, transmitter or building automation system reads this resistance change and converts it into a temperature value.

The Pt1000 element used in the RSPT1000 has a sensitivity of 3.85 ohms per Kelvin. This means the resistance changes in a predictable way as temperature increases or decreases. Because of this stable relationship, the sensor provides accurate and repeatable temperature measurement in duct air applications.

C. Why It Is Used

The Honeywell RSPT1000 is used to measure air temperature inside ducts in HVAC and ventilation systems. Accurate duct temperature measurement is important for maintaining comfort, energy efficiency and process control.

It is used because it helps HVAC systems monitor the actual air temperature in discharge air, return air and outside air ducts. This data helps controllers regulate heating, cooling, ventilation and air handling performance.

The sensor is suitable for applications where dependable duct temperature feedback is required for automation, monitoring and control. Its Pt1000 element provides stable temperature measurement, while the duct-mount design makes it easy to install directly into ventilation and air conditioning ducts.
