This sensor can measure the mass to weight relationship and study how different pulley systems affect the effort needed to lift weights. It can also be used to measure push/pull forces and impacts.
The force sensor is contained in a metal box. There is a hook at the bottom of the box that can be connected to various pulling loads. A simple bumper (for push/impact measurements) could be made and attached using a bolt which is placed through a length of plastic tubing.
The sensor can be hung from a universal laboratory stand via a rod through the hole in its box. This sensor can be operated either facing upwards, downwards or at any intermediate (including horizontal) position.
Connect the sensor to a voltage source (USB module, Display unit or Battery module). To zero the reading, just press the sensor's push-button for about 3 seconds.
