New features available with the belt weigher 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 weighing 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 belt scale 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 weighers 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 belt scale 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 belt scale is widely used in industries using belt weighers and weighfeeders, especially the cement, aggregate and mining industries.
Operating with any belt scale or belt weigh feeder with up to four strain gauge load cells, or any LVDT equipped belt weigher, or weighfeeder, the belt scale processes belt load and speed signals for accurate flow rate and totalised weight of bulk solids.
The patented electronic load cell-balancing feature makes the belt scale a world leader in system accuracy.
