WebA thermistor provides feedback to a temperature controller that monitors the thermistor’s temperature and turns heating and cooling elements on or off to keep it at a desired temperature. The temperature controller sends a small amount of current, called a bias current, across the thermistor. WebThe following NTC thermistor parameters can be found in the manufacturer's data sheet. This is the thermistor resistance at the temperature specified by the manufacturer, often 25°C. Indicates how much the resistance can vary from the specified value. Usually expressed in percent (e.g. 1%, 10%, etc). WebAs a refrigerator temperature control, refrigerator thermostat has only one function — controlling the refrigerator's cooling system by turning it on or off to ensure that the temperature inside the fridge stays in the correct range of 33 to 40 degrees Fahrenheit. how did veganuary start
