The beauty of the ERC is that it is a non-contact system. In other words, the ERC does not touch the yarn at all! It measures the rotations of the Skein-winder and the user enters into the ERC's computer what each rotation (revolution or circumference) is equivalent to in either inches or centimeters. Then, as the skein-winder winds the yarn on (or off) the ERC measures the length of the yarn based on the rotation count multiplied by the measurement for each revolution. Not quite as accurate as the EYM which measures every inch of yarn, but the ERC is extremely accurate nonetheless. The unit can measure:
It can also measure target quantities of these three measurements. For instance, the user can tell the ERC that each revolution (circumference of the skein) is 55 inches and that they want to measure 235 yards. The ERC will keep track of the total measurement and all of the mathematics behind the scene as the yarn is being wound on and then beep as it reaches the 235th yard. If if is connected to our motorized skein-winder (or motorized ball winder), it wil also turn off the motor drive automatically! We are the only company that measures yards, meters, and rotations and then turns a motor drive off. This is sophisticated technology especially when combined with our heavy duty winding mechanisms.
