Cost-effective monitoring of roller gap separation(15/02/2011)
Measuring the gap between rollers, or checking parallelism to close tolerances is a measurement task that can be achieved using RDP Electronics' E725 digital indicator in combination with a pair of LVDTs. Thanks to the E725’s capability to accept inputs from two separate transducers - in this case LVDTs of the same type and range - the indicator can be set to display individual readings, the average of both, or to check the difference to determine how parallel the rollers are.
