Temperature HVAC Sensors

Introduction to Temperature HVAC Sensors

What is it?

Temperature sensors for HVAC systems are devices that measure and monitor the temperature of air or water in heating, ventilation, and air conditioning systems. They can be used to control and regulate temperature levels in different zones or areas of a building.

Why we use it?

We use temperature sensors to improve occupant comfort, optimize energy usage, and ensure system performance by monitoring and controlling temperature levels in HVAC systems.

How it works?

The sensor typically contains a sensing element, such as a thermistor or thermocouple, which interacts with the air or water to produce a signal proportional to the temperature. The device then calculates the temperature based on the magnitude of the signal produced.

Major brands that manufacture it

Some of the major brands that manufacture temperature sensors for HVAC systems include Honeywell, Johnson Controls, Schneider Electric, and Siemens.


There are different types of temperature sensors, including resistance temperature detectors (RTDs), thermocouples, and thermistors. Some models may also feature additional functions, such as humidity sensing or wireless connectivity.

How do we select it?

When selecting a temperature sensor, consider factors such as measurement range, accuracy, response time, compatibility with the HVAC system, and communication protocols. Also, make sure the sensor is compatible with your existing control and automation systems.

How to install it?

Temperature sensors should be installed in the location where temperature needs to be measured, such as a duct, pipe, or room. They should be mounted securely using appropriate fittings or adapters, and any necessary wiring connections should be made to the building automation system or controller.

Wire connections required to receive the signals

The wire connections required to receive the signals from a temperature sensor may vary depending on the specific device and building automation system. Typically, they will require a power supply connection and a communication signal wire that connects to the building automation system or controller. It's important to refer to the manufacturer's installation instructions for proper wiring connections.
