A digital thermostat is a digital temperature controller.
It measures an object using temperature sensors such as thermocouples, side temperature resistors, and thermistors. The digital thermostat calculates the temperature corresponding to each temperature sensor from the obtained output signal, and generates an electrical signal to operate the device that heats or cools the object according to the set value.
By turning on and off a heating device such as a heater, this electronic device heats the object to the set temperature and then maintains it at a constant temperature.
Temperature control methods include simple ON/OFF control, which emits an ON signal when the temperature falls below the set temperature and an OFF signal when it reaches the set value, and PID control (Proportional-Integral- Differential Controller), which emits a longer OFF signal as it approaches the set temperature and a longer ON signal as it leaves the set temperature.
Digital thermostats can be used for temperature control because they can display the signal from the temperature sensor as a numerical value.
Since it can perform automatic return control that repeats ON/OFF, the object can be regulated to a certain temperature.
If it has a function to perform manual reset type control that does not turn ON automatically once it turns OFF, it can be used as an over-temperature protector or an abnormal temperature alarm.
Therefore, it is used to maintain and control the temperature of animal incubators, water temperature in aquariums, food warming, greenhouses for plants, etc., where temperature control is necessary, the temperature needs to be kept constant, or the function to react to abnormal temperatures are used.
Digital thermostats use various temperature sensors to measure an object, calculate the temperature corresponding to each temperature sensor from the output signal obtained, and produce an electrical signal to operate a device that heats or cools the object according to a set value.
The temperature sensors used include thermocouples, which use the electromotive force generated at the contact point by making a circuit with the tips of two different types of metal wires, resistance temperature detectors, which use the electrical resistance of a metal or metal oxide whose electrical resistance changes with changes in temperature, and temperature sensors such as a thermocouple, which uses the electrical resistance of a metal or metal oxide whose electrical resistance changes with changes in temperature, and a resistance temperature detector.
