May 8, 2006 -- Peterborough, Canada -- New features available with the Milltronics BW500 integrator make it a powerful integrator for use with both belt scales and weighfeeders. The new features include a second speed sensor input, and optional moisture sensor and incline sensor inputs.
The detection of broken belts, defective speed sensors and other differential speed changes are now possible with the addition of a second speed sensor input. The user can set a limit to monitor the speed differential between the two speed sensor inputs. The second speed signal is compared to the primary speed signal and will initiate an alarm condition if the second speed signal is outside the programmed high and low alarm setpoints. This feature can act as an early warning system to avoid costly process interruptions and equipment breakdown. The secondary speed sensor is especially useful on variable speed conveyors, and may also be used to detect a malfunction in the primary speed sensor.
An optional moisture sensor input has been added as an alternative to a fixed moisture percentage value resulting in even greater accuracy. The new moisture sensor input value allows the BW500 to compensate for the moisture in the material being weighed. It factors out the moisture component of load, rate and total calculations. The resulting factored values are the dry mean values of the material being weighed without any additional weight for moisture.
Accuracy is also improved with the addition of an incline sensor input for belt scales mounted on variable incline conveyors. Incline compensation is used to compensate for the varying vertical force component applied to the belt scale due to changes in incline of the conveyor. As the incline of the conveyor increases, the vertical force component applied to the belt scale decreases requiring a recalibration at each angle to maintain the expected accuracy. The Milltronics BW500 incline compensation feature automatically adjusts load readings as the incline of the conveyor changes, eliminating the need for costly and time-consuming recalibrations.
First launched in 1999, the BW500 is widely used in industries using belt scales and weighfeeders, especially the cement, aggregate and mining industries. Operating with any belt scale or weighfeeder with up to four strain gauge load cells, or any LVDT equipped belt scale, or weighfeeder, the BW500 processes belt load and speed signals for accurate flow rate and totalized weight of bulk solids. The patented electronic load cell-balancing feature makes the BW500 a world leader in system accuracy.
