Temperature Control & Process Heating

We understand the importance of temperature control and ensure a comprehensive range featuring leading automation vendors, including ABB, Omron, Panasonic, Schneider Electric, Eurotherm, West Instruments, and RS Pro. We offer a variety of temperature controller types, covering enough variants to allow users to tailor them to specific applications or processes.

Each industry use temperature control differently, some examples include:

  • Domestic applications with simple on-off functionality and sensors manage temperature through heating via radiators or cooling via air conditioning, refrigeration, and freezers.
  • Industrial manufacturing monitor and maintain both high and low temperatures throughout their processes within set tolerances for plastic moulding, metal smelting, ceramic firing, and composite curing.
  • In packaging, temperature sensors are deployed throughout the process of sealing, forming and wrapping,
  • Food and beverage industries use temperature control for storing, cooking, chilling, heating, and processing.

Types of temperature control systems and controllers

Open loop systems deliver a control signal with no reliance on an input signal to act as a basis for on-off decisions. These can be simple non-contact devices with a Digital Temperature Controller display built into your system or temperature probes used in quality assurance.

Closed loop, on the other hand, uses an incoming signal to regulate its output according to a predetermined setpoint defined by the user or a higher-level controller Closed-loop temperature controllers can then be split into three sub-varieties: on/off, proportional and PID

  • On-off Sensors like thermostats will action a simple on-off decision and make a correction before the process temperature exceeds the acceptable tolerance, much like a domestic thermostat controlling your heating system.
  • Proportional controllers add more specific control. Instead of using a simple on/off signal they can deliver appropriate correctional actions, heating or cooling, to achieve control within the temperature tolerances; the idea being that eventually, they will reach a steady state with little or no fluctuation (hysteresis).
  • PID (proportional-integral-derivative) controllers are more intelligent and add further control. PID controllers use the difference between the temperature level and the desired setpoint and then cycle the power until this difference is minimised. Like proportional controllers, they apply the corrective action to the offset from the setpoint, but in addition, they use an integral function to control the offset error, while the derivative function suppresses overshoot
