HVAC Temperature SensorHVAC Temperature Sensor
Product Description:
An HVAC (Heating, Ventilation, and Air Conditioning) temperature
sensor, also known as a thermostat, is a device used to measure and
control the temperature in a heating or cooling system. It is a
crucial component in HVAC systems as it provides feedback to the
system and enables it to maintain a desired temperature.
Here's how an HVAC temperature sensor typically works:
1. Temperature Measurement: The sensor measures the ambient
temperature in the space where it is installed. It can be either a
simple bi-metallic strip, a thermistor (a type of resistor whose
resistance changes with temperature), or a more advanced electronic
sensor like a thermocouple or a resistance temperature detector
(RTD).
2. Comparison and Control: The sensor compares the measured
temperature with the desired temperature set by the user. If the
measured temperature deviates from the setpoint, it sends a signal
to the HVAC control system.
3. HVAC System Response: Based on the input from the temperature
sensor, the HVAC control system determines the appropriate action
to adjust the heating or cooling output. It may activate or
deactivate the heating or cooling equipment, adjust the speed of
fans or dampers, or open/close valves to regulate the temperature.
4. Feedback Loop: The temperature sensor continuously monitors the
temperature, providing feedback to the HVAC control system. The
system adjusts the output accordingly to maintain the desired
temperature within a certain range.
Types of HVAC temperature sensors:
Bi-metallic strip: Consists of two different metal strips bonded
together, which bend with temperature changes and trigger a switch.
Thermistor: A temperature-sensitive resistor that changes its
resistance based on temperature.
Thermocouple: A device that generates a small voltage proportional
to the temperature difference between two junctions of different
metals.
Resistance Temperature Detector (RTD): A type of temperature sensor
that measures resistance changes in a wire or element as the
temperature varies.
