Most frequent questions and answers

Model 4.3 is available for up to 2 scales, Model 5.0 is available for up to 8 scales.

Model 5.0 has a larger touchscreen (7″ as opposed to 4.3″) and has additional features that are not available with Model 4.3, such as automated text and email reporting.

Yes, the scale can be used on an automated stacker.  Any stacker that moves up and down will need an additional component to monitor the changing angle.

Yes, inconsistent loads do not bother the scale.

Flat belts are not a good application for the scale.

Yes, this is an option and just requires an additional sensor.

VFDs are not recommended, although scales have been successfully installed on VFDs that maintain a constant 60 Hz.

Typically a scale can be installed in about 1 hour.

There are several ways to calibrate the scale.  A known load may be run across the conveyor and compared with the tons accumulated by the scale, belt cuts can be done (with consistent feed) and compared to the TPH reading on the scale, or the conveyor can be discharged into a truck or loader bucket and the tons compared.
