What is the temperature regulator?
and the temperature controller is a device that controls the heating or cooling system outputs. This control is achieved by connecting temperature sensors installed in a heated area or a control system. Data captured sensors are compared to the user's prefix; If the temperature in the system should deviate from it, the controller either activates or deactivates the source of heat or cooling. There are three main categories of temperature controller operation: ON/OFF control, proportional control and PID Control. Each meets the same basic temperature control function, but offers different levels of sophistication and functionality.
Heating and cooling systems usually consist of three basic ingredients: thermal source, control mechanism and one or more sensors. Depending on the complexity of the system and the level of accuracy required when temperature control, the mechanisms of control and sensor may not be more complicated by Than and Bimetal switch. Extended, complex production systems may contain a sophisticated, on the other handThe computer controls that control several heat sources based on data obtained from many sensors. To achieve this range of control interventions, systems depend on the thermal dependent one of the three basic types of temperature controller.
The first category of temperature controller is the ON/OFF unit. This is the simplest of all controllers and offers one level of control. With this type of driver, the heat source is running in full power and is either off or depending on the system temperature. An element known as the on-off differential is built into this type of driver, which prevents damage to relays, contactors or valves “vibration” if temperature changes occur too quickly. This function allows the system temperature to exceed the set point by a particular marginity of the driver switch from turning the cycling on/off rapidly.
The second type of temperature controller is a type that is capable of proportionalSetting the temperature. This driver reduces the power supply in which the heating runs when the reference set is approaching. This prevents the system temperatures from exceeding the set point, as is the case on the type ON/OFF drivers. If the temperature goes too far from the set point due to environmental problems, the driver then acts as a unit on/off either maintaining the power supply full or off.
The third type is proportional with integral and derivative (PID) controller. This type of driver works in the same way as the standard proportional unit, but includes two other, time -dependent adjustments. These adjustments are usually marked as "resetting" and "speed" on the device and allow extremely stable temperature control in applications where the system load requirements often change. But this variant, but requires fine tuning of all settings to work properly.
