What is a Temperature Controller?
A temperature controller is a device that controls temperature by comparing the measured temperature with the set temperature.
It takes in the temperature detected by a sensor such as a thermocouple or thermistor, compares it with the set temperature, and outputs an electrical signal. The output signal is then used to control heaters and cooling devices to maintain the set temperature. In the home, temperature controllers are used in water heaters and air conditioners, and in industrial applications, they are often used to keep outdoor storage tanks warm.
Uses of Temperature Controllers
Temperature controllers are used to adjust and control the temperature of liquids and gases.
In industrial applications, they are often used to control process temperatures. Automatic control using temperature controllers minimizes the use of steam and electricity, contributing to energy conservation.
Also, for use in general household products, temperature regulators are used in water temperature controllers for tropical fish, water heaters, and air-cooling equipment such as air conditioners and refrigerators.
Principle of Temperature Controllers
Temperature controllers are mainly used to control heaters and cooling devices by calculating and comparing the measured and set temperatures. For a system whose temperature is to be controlled, it generally consists of a temperature measurement sensor, a temperature controller, and heating and cooling equipment.
The temperature measuring sensor measures the temperature of the object to be controlled. Resistance temperature sensors and thermistors are used. The temperature controller is an electronic device for control. It controls output by feeding back temperature. Air conditioners and heaters are used for heating and cooling equipment. Air conditioners use a compressor to compress refrigerant and can both heat and cool.
Temperature Regulator Control Method
There are two types of temperature controller calculation outputs: continuous control and ON-OFF control.
1. continuous control
PID (abbreviation of Proportional, Integral, Derivative) control is a control method that calculates input signals using proportional, integral, and derivative elements.
In severe processes where overshoot cannot be tolerated, fine adjustments are made with differential control. Proportional control, integral control, and derivative control are abbreviated as P control, I control, and D control using the initial letter of each word.
- P Control is proportional to the deviation between the input value of the temperature measurement sensor and the temperature setpoint.
- I Control eliminates the deviation between the input value of the temperature measurement sensor and the temperature setpoint.
- D Control fine-tunes the difference in temperature change due to external factors.
2. ON-OFF control
ON-OFF control compares the measured temperature with the set temperature and turns on or off the cooling/heating equipment. Compared to continuous control, ON-OFF control is simpler and can be introduced at a lower cost.
Other Information on Temperature Controllers
1. thermostat temperature controllers
Thermostats are simple temperature controllers that have been around for a long time. It uses the expansion and contraction of a metal or liquid due to temperature control by turning contacts or valves on and off. They are often used to regulate the cooling water to radiators in automobiles and other vehicles, and to control the temperature of electric kettles. Thermostats are available in metal and liquid expansion types.
- Metal Type Thermostats: Metal type thermostats use a temperature sensor called a bimetal. This is a plate made of two types of metal with different thermal expansion rates, and uses the expansion and deformation caused by heat as an electrical contact point.
- Liquid Expansion Thermostats: Liquid expansion thermostats use the force of expansion and contraction of a liquid enclosed in a container as an electrical contact point. Liquid expansion thermostats are characterized by their ability to increase electrical capacity. Both types of thermostats do not require a power supply for control.
2. temperature controllers and heaters
Temperature controllers control temperatures in a range above ambient temperature by issuing control commands to heaters. Since each temperature controller has a fixed controllable power capacity, a separate drive device such as an electromagnetic switch must be provided when a large-capacity heating device is used.
To control temperatures below ambient temperature, a chiller or other cooling device is used. The specifications and capacities of the temperature controller, heater, and chiller must be appropriate for the intended use. A temperature sensor is also required for temperature control.
3. indicating controller and temperature controller
A temperature controller is a type of indicating controller. Indicating controllers control not only temperature but also humidity, flow rate, pressure, and many other factors. Both indicating controllers and temperature regulators are arithmetic devices, and sensors and refrigeration equipment are required separately.
