What is a temperature controller?
A temperature controller is a device that is designed and built to regulate temperature.

Are there different types of temperature controllers?
Yes.  There are three basic types of temperature controllers that we offer at Oven Industries.  The three basic types of temperature controllers are On/Off temperature controllers, Proportional Temperature Controllers and PID temperature controllers.

What is the function of a temperature controller?

A temperature controller with varying degrees of defined accuracy controls the temperature of a process.  The temperature controller has a sensor such as a thermocouple,  RTD, or thermistor  that provide the input  information to  the temperature controller.  The temperature controller compares the actual temperature information with the  set temperature that the user has provided.

On/Off Temperature Controllers are defined as follows:

There are two settings to this temperature controller.  It is either on or off.  In heating it is on when the actual set temperature is below the set point. In cooling it is on when the actual set temperature is above the set point’. This is a typical heating and cooling thermostat.  Often times the on off temperature controller is programmed with a differential.  The differential will turn on or off the system after the actual temperature has exceeded either side or the on off set point for a period of time.  On/Off temperature controllers are not as accurate or precise as needed in many operations. Oven Indus ties offers several types of these temperature controllers.

Proportional Controllers are defined as follows:

A Proportional controller is an enhanced version on the on off temperature control which gives you better performance .  The proportional features functions from a band around the set point.  It keeps the temperature controller from cycling on and off constantly.  They do this by reducing percentage of power as you get closer to the set point. It causes the unit to move beyond the set point but remaining in the band..  This type of controller will use less energy to maintain temperature. Oven Industries offers several types of these temperature controllers.

PID – Proportional Integral Derivative Controllers are defined as follows:

In temperature control systems where the thermal mass is less an advancement beyond the Proportional temperature controller are the features of integral and derivative. Time is the unit of measure that drives the integral and derivative features.  The integral and derivative features in a temperature controller are called Reset and Rate.  This temperature controller will automatically adjust to compensate for the changes in temperature.  The PID temperature controller provides the most accurate and consistent temperature controller. Oven Industries offers several types of these controllers.

What is a temperature sensor?

A temperature sensor is a device that is designed and built to sense temperature.  The temperature sensor provides input to the temperature controller.

What are the different types of sensors and how do they sense?

There are several types of temperature sensors.  However the major temperature sensors fall into three basic categories.  These categories are

  • Thermocouple
  • RTD
  • Thermistors
