Industrial temperature controllers have been part of the equation for centuries. As various fields have changed and advanced, though, so to have the temperature control devices, and the technology has expanded greatly over the past fifty years.
The Early 60s
By the early 1960s, things were already starting to move and change. While moving coil full DIN temperature controllers were the standard, electronics were starting to invade almost everything, and controllers were shifting with that. Open frame PCB controllers were introduced, allowing for proportional control for the first time, which meant a level of accuracy that just wasn’t previously available. Naturally, there were drawbacks, but it certainly began to set a new standard.
Reduction in size characterized the shift in temperature control during the 1970s. Analog controllers grew smaller and smaller, yet they weren’t changing at all. Digital controllers were the only growth market. Even today, you’d find little difference in the technology behind analog models.
This decade was a digital explosion in almost every aspect of industry, and temperature control technology was certainly part of that change. Where guesswork made up most of the controller settings in the past, pushbuttons and digital displays meant increased accuracy almost everywhere. It helped reduced temperature overshoot and changed the way disturbances were handled.
The digital shift is far from over. Auto-tune is now available, and almost no manual interaction is necessary. This naturally results in fewer errors. Add that to the fact that temperature control can be tied into other monitoring systems in place and the fact that most of it can be controlled from an online interface anywhere in the world, and you have an ideal system individuals couldn’t have dreamed about as electronics were first introduced.
The trend toward easy access and customization will only continue in the years to come. Stick with us for all of the latest upgrades in temperature control.
