Temperature controller working principle and classification
Temperature Controller, Also known as thermostat (Thermostat), Also known as temperature control switch, thermal protection, Divided into mechanical (bimetallic, liquid expansion, mechanical) And electronic (thermistor) of the two categories.
Mechanical temperature controller is divided into (bimetal, liquid expansion, mechanical): It is mainly based on the work environment temperature changes, Mechanical thermostat in the switch inside the physical changes, Resulting in some special effects, Turned off or produce a series of automatic temperature control operation of the thermal protection.
Electronic temperature controller (thermistor): Electronic components in different temperature conditions, To the circuit to provide different temperature data, After the electronic chip gathers the temperature data point, Automatic control of electrical temperature.
2. The temperature controller works
Temperature controller works by (temperature control switch, temperature sensor) on the ambient temperature automatically sampled, Real-time monitoring, Temperature controller When the ambient temperature is higher than the control set temperature control circuit start, Can be set to different temperature control.
The temperature controller consists of a switching display element, Setting element, Comparison operation element, Output components of the four major components. When the (temperature control switch, temperature sensor) to the field temperature is converted into electrical signals to the control chip, Control chip conversion display element, The electrical signal into a digital display or analog signal indicates, And after the comparison with the set value of the internal setting element, Through the output element output to the controller, The controller then controls the heater / cooler.
3 temperature controller application examples
In today's society, Automation / humanized home appliances is the development direction. Temperature controller will become household appliances (wall-hung boilers, air conditioners, induction cooker, rice cookers, water heaters, etc. ) will use accessories. The development of intelligent temperature controller, To people's lives has brought convenience and comfort. The main role of the thermostat is divided into the following categories.
Convenient: automatic timing in advance or delay every day, switches, household appliances, Eliminating the need for manual operation, For the present family to provide a convenient control;
Comfort: Every time of day, Electrical appliances can be set in accordance with the human body comfortable temperature automatically adjust;
Energy saving: change the backward extensive temperature switch control, change the advanced accurate room temperature automatic adjustment, Plus sub-time-controlled indoor temperature operation, Change the extensive electrical refrigeration or heating, a large number of saving electricity consumption;
Environmental protection: automatic adjustment of the temperature controller, because the ambient temperature constantly changing, Intelligent temperature controller automatically adjust to meet people's needs, Reduce the electrical unnecessary operation, The environmental protection provides more control of the system.
