Temperature controller is a measurement device used on temperature control. Thermocouple-type and resistor-type temperature controllers measure temperature electronically, obtaining the temperature change from the sensor and sending the measured data to the electronic processor. The output device will then control the temperature variation within a specific range.

Delta’s DT series temperature controller has fast output response, accurate PID parameter auto-tuning, support Modbus communication protocol and is built-in with various output types, allowing different systems to reach a stable control status very quickly. Besides, all series are complied with international installation dimension and CE, UL international safety approvals.

What is a digital temperature controller ?

A digital temperature controller is a electronic control system used for holding a stable temperature ranges over time.

  • The controller works by reading the input temperature with the help of a sensor (thermocouple or resistive thermal devices) and then compare it to levels set by the user (setpoint).
  • Then depending on the result, the controller sends output signal to a control element usually connected to the outlet socket thermostat.
  • The control element acts upon a signal and applies heat or cold to maintain the setpoint. Fans and heaters are usually used as a control element

Which sensor is used to measure temperature ?

Most commonly, temperature sensors are used to measure temperature in circuits which control a variety of equipments.

There are different types of temperature sensors used in the market today including resistance temperature detectors (RTDs), thermocouples, thermistors, infrared sensor, and semiconductor sensors. Each of them has a particular operating parameters. These sensors come in different varieties, but have one common thing: they all measure temperature by sensing a change in the physical characteristic.

How does a temperature controller work ?

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.

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 setpoint, and provides an output to a control element.
