[QUOTE="jon.newbould, post: 6522299, member: 142493"] Hi - It is relatively easy to do all you need is a pressure sensor 4-20mA/0-100bar range on the return line of the ram connected to an arduino or small PLC. As you lift your load the downward pressure is read by the pressure sensor using an empty loader this is then set as the zero point. Add a known weight such as 500kg fertiliser bag this then gives you the scale of the 4-20ma so for example 10mA is 500kg there fore the 1ma is 0.02kg. [/QUOTE]
