What are the types of temperature controller? How to choose?
When the manufacturer purchases the temperature controller, is it focusing on the appearance or performance. Different manufacturers have different needs. There are so many types. How to choose? Today we will organize for you:
1. The main types are based on the appearance of the thermostat: the general -wheel dial, the ordinary key type, and the advanced intelligent programming LCD display type.
When there is no one in the room, it can be set to lower temperature. This reduces both energy consumption and improves comfort. Electric Filter Fan Cabinet Heater Fan Heater with Thermostat Advanced smart thermostats have adaptive functions. It can automatically calculate the start time of the system to reach the temperature you want at the time you set. Generally, the system can be adapted to the surrounding environment after 3 days of powering for 3 days. With the popularity of the LCD touch screen, the temperature controller has also applied the touch screen in recent years.
Ordinary dial -wheel and ordinary keys temperature controllers are relatively simple, and you can directly adjust according to the needs of users. The high -level intelligent programming liquid crystal display temperature control can be booted at the scheduled time, and it can be set to 4 different temperatures per day (some can multiple different temperatures in multiple time periods). Generally, the factory setting is suitable for most cases, reducing the troubles set by user settings.
2. According to the different temperature materials, it is divided into mechanical (dual metal pieces) temperature controller and electronic temperature controller (PTC and NTC).
The working principle of electronic temperature controllers: Electronic temperature controller currently uses PTC or NTC materials as the temperature sensor, converts temperature numbers into current signals, and then controls the system to control the system after chip analysis.
The working principle of mechanical thermostat: The alloy tablets of two different temperature expansion coefficients feel bending and deformation after indoor temperature. The alloy film with a large expansion coefficient promotes the extension of the alloy films with a small expansion coefficient, and the closed and disconnection of the contacts is promoted to achieve the power control and power failure of the thermostat.
3. Different from the detection method (measurement temperature) are mainly divided into room temperature, ground temperature, and dual temperature temperature controller.
Room temperature temperature controller: The air temperature at the installation location set by the temperature converter in the case of the temperature controller is used as a basis for the automatic control of the system circuit to be automatically controlled.
Ground temperature temperature controller: The temperature of the installation position through external probes is used as a basis for the automatic control of the system circuit.
Double temperature controller: The air temperature of the installation position through the temperature -built -by -temperature sensing probe at the temperature controller, and at the same time through the temperature of the installation position (ground) of the external probe to ensure that the ground temperature is not higher than the limited temperature, within the case, within it The probe detection data is the device that systematically controls automatic control.
From the above introduction, it can be seen that the type of temperature controller has a diversified trend, but the independent control of the traditional spinal temperature controller is still the most important control method in recent years. When choosing the temperature controller, you need to choose according to the function of the room and your own needs. The quality of good quality is the most important.
