Re: Band saw blade tension


 

Hi George
S-type load cells?work in both tension and compression and these ones have a 7/16 UNC threaded hole in top and bottom, which I made pivot pin type connections to.
The blade is just silver soldered to the connectors.
Because I bought the loadcell and the reader as a pair, the loadcell just plugged into the reader.
Totally Chinese instructions that I could not decipher and?no amount of pressing and holding buttons?etc could I make it read in Lb's or Kgs though its supposed to.?
The reader?reads in units of 20g, Reading of 10,000 units = 200kg. A minor pain in the butt but otherwise its been faultless.??
When I calibrated it against the research grade 500kg loadcell on the tensile tester at the engineering school, the thing calibrated perfectly with slope of 1:1 and intercept of zero, so no need to worry about the accuracy of these $20 loadcells.? Even the $5 Airport luggage weigh scales were as accurate.
All loadcells?creep a little if left under load, I found?out too, but if you read it within a minute or two it's stable.

John,

How is your load cell set up to measure tension.? where can i get a load cell appropriate for this?
