That must be the first video I have ever seen on RU-vid without a thumb down... there's a reason for that and I hope it stays that way. Many thanks for the great explanation Niels!
3:36 more people should watch this part. I've seen too many arguments on the internet over 1 set of pedals being inferior to another based solely on the LC's rating.
So many in the Simracing community talk about load cells, their cons, but never show them. Instead they show elastomers to explain how much force is calculated. Elastomers are probably the weak link in load cells systems, Their accuracy depends on external conditions, temperature, repetitive pressures. Size, softness, number of elastomers reduce precision of the force calculated in the load cells.
Hi Tom, The amount and type of elastomers actually have no effect on how the force is calculated. If you put a force of 10kg on a single elastomer or on a longer softer stack of 3 elastomers, it will always transmit 10kg to the load cell. Depending on what rubbers/elastomers are used there may be an effect of hysteresis which can slightly alter the force transmission in a short period of time, but when properly designed this effect can be nullified (we have equipment to test our elastomers under load over time). Please note, also pedals which use a hydraulic pressure transducer need a spring element in order to get any movement in the pedal, and often this is a rubber or elastomer as well. Any calculations shown with regard to elastomers typically address the amount of movement (what you feel under your foot when pressing) you get when pressing a certain amount of kg. The effects/characteristics you describe may indeed influence the pedal feel, but regardless of the condition or design of the elastomer, 10kg in is 10kg on the load cell. If you have any further questions, let us know. Best regards, Your HEUSINKVELD Team
hey said it its from his sim center professional line. made for use in sim center's and other sim race attractions. they are not listed on the website.
@@bullgearvr4418 Well .... too late. It helps to check the HE website regulary. A good time where you have a good chance to get a Pedal set is often the friday evening.
For the pedal, you mentioned 10kg applied will result in 20kg at the load cell. however, the Spring inserted right there...in the middle, does it. absorb some of the 20kg? or it only act as a buffer....the delay the 20kg... during sudden compression....

Great video, thank you, now I understand the principal of this kind of load cell system. Question if you have time, (Disclaimer: I dont own Heusinkveld pedals, but wish I did, so this is not about your pedals or load cells but a similar system), what are the potential causes that one of these load cells is working fine one minute and then the next suddenly only outputting 40% travel?
Hello Alex, Thanks for your question. Loadcells are very reliable, but if they show a fault it can have a lot of causes. Possible reasons are: EMI interference, a broken wire, severe overload/bending of the load cell etc. It's really difficult to troubleshoot without doing a few tests. We advise you to email the support team of your current pedal brand to troubleshoot and sort out any issues. Best regards, Your HEUSINKVELD Team.
@@HeusinkveldEngineering Thank you so much for responding too! Really appreciate it. I ended up doing a quick strip down of the pedal and found that the spring connecting from the pedal arm to the load cell was snapped... This seems like an incredible design flaw in this brand of pedal. One day I'll be able to afford a set of your pedals and will not hesitate, as yours appear to be built to last. Thanks again!
The measured value will be linear with the input by the driver. A potentiometer always have some sort of linkage, if it's not driven by gears, and there is a slight difference between the input and output. Also, it not gonna fail, dust is not an issue, you don't have to clean it.
Using a linear spring on the small loadcells means you effectively measure pedal position, because the tiny spring force grows linear with displacement. It has proven to be very accurate and reliable, and indeed there is no slop and slack in the system. So if you release the pedal 0.1mm, you get a change in pedal output.

Short answer, anything more than 8 bit probably doesn't matter. Long answer: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-rcqiw6TNj_4.html Perhaps we'll do a more compact video about this in the future.
@@NielsHeusinkveld The Sim Pedal Sprint brake, according to specs, supports up to 65kg of force. So, is it 65kg on the load cell or 65kg on the pedal ? Thanks
yep it does all come one simple coprelation the force level which you want to measured and scale of loadcell for egzample if you want measured force like 1000 grams -1500 grams you dont take for this 50 tons loadcell because measuring be very not precise in fact if loadcell/forcemeter have error like +/-0,1% from full scale that mean error for let say 10 tons loadcell = +/-10 kg sos cuh you be unable to measured such low force like 1-1,5 kg with high precision because error is biger than this :D so yea size of loadcell i mean scale is veeeery important .i have loaddceel up to 2 tons with error +/- 0,1% what mean +/- 2 kg its not bad but for force which i wat measured max at like 500 kg thats way to big scale if i buy than loadcell to 500 kg i get precision like +/- 0,5 kg but still 2 is not bad ;) ...also so such if you want measured force like 5 tones in prediction some heavy load you dont buy loadcell to 1 tons because you damage it in 1 attempt of measuring something ....
