Hi, my name is Andy Lewis with Innovative-IDM, and today I’d like to talk to you about that dime-a-dozen controller located in your plant that is often overlooked, and generally serves its purpose day in and day out. Although they may break down occasionally, I want to make sure that you’re choosing the right temperature controller for the right application.
There are four categories of temperature controllers. There’s the general purpose, the economy, a modular version and the PLC version. All of these have features, benefits and advantages. For the most part, they are all going to have a basic alarm system. Some of them are going to have a more advanced PID-Loop, ramp, soak, temperature changes. And, for the most part, whenever it comes down to the alarms that they put out or the amount of thermo-regulators that they can input within their own controller, the number increases.
General purpose controllers meet a wide range of applications; generally needs for the food processing industry, packaging, extruders, semi-conductors, etc. They’re around there, they’re a dime-a-dozen, you see them all the time.
Next up, is more the economy type and they are relatively simple in function. They don’t have all the bells and whistles that all the other ones are going to have. They are basically going to be able to tell you “Hey! My temperature is this, I need to be at this level, and I’m going to get to this level over this amount of time.” That’s it.
Next, is a modular type, which allows you to have increased capability or decreased capability based upon changes in the application, changes in the product, etc. It all comes down to how many thermo-regulators and controllers you use in conjunction with each other.
Finally, is the PLC version, which is the most advanced version and has the PID instruction in it. Basically, what it means is that it’s very advanced in the way it controls, how tightly it controls the temperature, how quickly it raises it, how quickly it lowers it, etc. That’s whenever the application has a very crucial temperature that can’t go above or below say one or two percent.
I hope this set of categories for the temperature controllers helps you out. If you need any more information, please go to our Knowledge Center at innovativeidm.com and once again, my name is Andy Lewis. Remember, Innovative-IDM is Home of the Legendary Customer Experience.
