AI Thread Summary
To achieve a set temperature of 900C in a furnace with a measured temperature of 909.2C and no offset option in the controller, one must account for the deviation of -9.2C. Users are encouraged to refer to the oven and controller datasheets, as well as the manuals, for potential calibration procedures. It's crucial to verify the accuracy of the temperature measuring device being used. One suggested approach is to conduct experiments to create a lookup table that correlates the desired temperature with the actual behavior of the furnace. The discussion highlights the need for practical experimentation in the absence of direct calibration options.

How to incorporate deviation -9.2C in furnace, while its measured temperature is 909.2C and Display temperature is 900. if there is no option of offset in controller. What will be the set temperature to achieve 900C.

Welcome to PF.

Can you post datasheets for the oven and controller? Do you have the Owners Manual and Service Manual for both? If so, there is probably some calibration procedure listed.

Also, what other temperature measuring device are you using to sense the "measured temperature"? Are you sure it is accurate?

This seems too simple, I must not understand something.

You have a thermometer you trust. You can't calibrate your controller. So, why don't you be the controller. Do some experiments and make a lookup table. Ask for the temperature that corresponds with the behavior you want.

PS: If you choose to have a lottery, I've got dibs on 890.8C.

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below.

Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
