View Full Version : How do I measure Pounds per Linear Inch (PLI) of a Continuous Wire? Daniel Walker 15th January 2008, 12:52 PM I have a customer who is wanting to measure Pounds Per Linear Inch of a continuous wire traveling between two rollers in tension. He is using a standard load cell transducer but doesn't have a meter/readout. How does PLI convert to lbf (pounds of force)? Can anyone help me?

Hello Daniel, I am not sure if conversions between the two entities are possible because they are two different things. Here is a conversion table (http://dershin.com/conversion.html) that shows possible conversions. Stijloor. ScottK 15th January 2008, 01:15 PM I've not worked with wire, but I have worked in web handling and caledering and it's been a while but... Seems to me that pli was measured at the nip point, not on the substrate. So PLI would be measured by lbs force divided by length of the nip rolls - assuming the force is distributed evenly. what are they actually trying to measure?

According to this (http://www.unc.edu/~rowlett/units/dictP.html), 1 PLI = 175.1268 N/m, and the conversion value for foot-pounds is 1 foot-pound = .738 N/m, so 1 PLI = ~129 foot-pounds. |
