Description
The Automation Components Inc (ACI) 121996 Thermistor Duct is used to measure the air temperature in HVAC systems. It is placed inside an 8″ protective case and has a thermistor element of 10 kΩ, which reacts to changes in air temperature and produces an electrical signal that changes with the temperature. This control circuitry of the system provides the control module to control air conditions so that fan speed, heating, or cooling outputs can be adjusted accordingly. The position of the assembly in the airstream and the thermistor properties of the assembly help in the measurement.
