What is a temperature controller?
As the name implies a temperature controller is an instrument used to control temperature. The temperature controller takes an input from a temperature sensor and has an output that is connected to a control element such as a heater or fan.
How temperature controllers do is work?
To accurately control process temperature without extensive operator involvement, a temperature control system relies upon a controller, which accepts a temperature sensor such as a thermocouple or RTD as input. It compares the actual temperature to the desired control temperature, or set point, and provides an output to a control element. The controller is one part of the entire control system, and the whole system should be analyzed in selecting the proper controller.
Updates of temperature controller have been done constantly by different manufacturers. Large number of manufacturers is producing the different varieties of controller. Updating of temperature controller has done continuously by the customer and different varieties of controller are manufactured to meet the requirement of the market.
Temperature controller is produced in large number and different forms of controller are produced by the manufacturers to facilitate the customers around the world. More and more customers/ market are evolving around the world. Temperature controller is available in several types to temperature measurement.
Temperature controller comes in more different types and they suits for wide different application and provides standard and unique features. They temperature controller comes in a wide variety and in styles, sizes, prices and capacities.
Programmable Temperature controller measures the temperature without any mistake.
Different types of controllers are:
1. On-off type
2. Proportional type
3. PID types
On/Off Control
The output from the device is either on or off, with no middle state. For heating control, the output is on when the temperature is below the set point, and off above set point. On-off control is usually used where a precise control is not necessary, in systems which cannot handle having the energy turned on and off frequently, where the mass of the system is so great that temperatures change extremely slowly, or for a temperature alarm. One special type of on-off control used for alarm is a limit controller. This controller uses a latching relay, which must be manually reset, and is used to shut down a process when a certain temperature is reached.
Proportional Control
Proportional controls are designed to eliminate the cycling associated with on-off control. A proportional controller decreases the average power supplied to the heater as the temperature approaches set point. This has the effect of slowing down the heater so that it will not overshoot the set point, but will approach the set point and maintain a stable temperature.
