Controllers for temperature, humidity or temperature control devices are quite popular devices on the market today. Most of these devices are commonly used in manufacturing plants. However, not everyone understands the details of these devices. So, in today’s article plctop.com will introduce you in detail about temperature controllers.
1. Overview of Temperature Controller
The temperature controller of a machine or device is used to control the temperature at a certain location or location. When using thermostats, they not only help to measure but also control temperature and humidity.
Currently, there are many different names for this device line, including: temperature sensor, temperature control meter.
2. Components of a Temperature Sensor
The thermostat is composed of 3 main components: sensor, thermostat and control device:
+ As for the sensor: This is an electronic device capable of sensing the chemical, physical, and biological changes in the state or process that they need to be investigated. The devices then turn the data they collect into signals, information about the state or the transformation taking place.
+ About the controller: After receiving the signals that the sensor has received, the controller will now be responsible for responding to the signals to control the information.
+ About the control device: The device will follow the rules of the controller set up in advance.
3. The role of the Temperature Controller
+Ability to control toggles
Switching on and off is the simplest task for a temperature controller. The most prominent function of the controller is the ability to control the power on and off. Therefore, when the temperature exceeds the specified threshold, the controller will automatically separate the 2 outputs. Conversely, if the temperature is below the set point, the output remains on.
+ PID Control
This is a specialized control that provides proportional derivatives associated with integrals. In addition, this controller provides proportional control along with 2 other additional adjustments. Part will help the unit automatically compensate with the system. The rest creates a smooth combination of components in the controller.
The PID controller is applied in systems that have to change frequently and have high transmission. The purpose of the controller is to assist in compensating the energy caused by the changes.
+ Proportional Control
The temperature controller is also capable of proportionally controlling the cycle rejection associated with on and off control. What this means is that when the temperature reaches the set time, the proportional control will reduce the power supply to the A/C.
This controller is quite simple to operate and is often adjusted by hand to keep the setpoint temperature as it was at initial startup.
4. Application of Temperature Controller
Controllers for temperature and humidity are now applied in many different industries from production activities of workers to industry.
+ Application in incubator temperature controller: Usually used to incubate duck eggs or chicken eggs, etc. cattle and poultry.
+ Application in controller for air conditioner: Air conditioner is a common device used in daily life, so a temperature regulator is an indispensable tool for this type of device.
+ Application in radiator fan controller: With the same features as air conditioners, radiator fans are often used in the production process.
Advantages of Temperature Controller
- Ability to operate equipment safely.
- Minimize power consumption.
- Minimize labor costs.
- Maintain thermal comfort.
- Clearly define maintenance issues.
- The best monitoring for the system.
Safety measures when using the device
- Check if the supply voltage is correct before connecting to the device.
- No contact with water or warmth: use the controller only within certain operating limits, avoiding sudden changes in temperature compared to the humidity of the air that are formed during condensation.
- Warning: Disconnect all electrical connections before performing maintenance.
- Mount the transducer where it is not accessible to the end user. The tool is not open.
- In cases involving damage or faulty operation, return the device to the distributor or Dixell Srl with a detailed description of the error.
- Consider the maximum current that can be applied to each relay.
- Make sure that the leads for the transducer, load, and power supply are separated and sufficiently far apart, not crossed or interwoven.
- In the case of applications in a technological environment, the use of a power supply filter in parallel with an inductive load can bring many benefits.
Through the above article, plctop.com and friends realize that temperature controllers bring many benefits to equipment used in industry and agriculture as well as in refrigeration systems.
