The Define Instruments PRO-WEI100 load cell panel meter has an advanced batching system designed for the weighing industry. It can be configured for filling or emptying applications and can maintain gross weight while simultaneously monitoring and controlling batch weight. If features output and input isolation, for easy interfacing with analog or serial inputs, PCs, PLCs, or HMIs.

The zero band feature provides a limit for the number of counts of zero offset allowed to accumulate, relative to the calibrated zero setting. If the accumulated zero offset becomes greater than this window then the controller displays the current loadcell value and does not zero. The PRO-WEI100 also has a zero maintenance feature which is used to automatically compensate for slow drift in loadcell output due to factor such as temperature change, rain, and dust accumulation over time.

The PRO-PRC uses input signal averaging to reduce noise and ensure stable measurements. If the change in input exceeds the averaging window value it will not average, ensuring fast response when there are large differences between readings.

You can configure up to 4 setpoints, depending on the number of relays you select. Your settings remain secure with PIN protection; the input calibration and setpoint functions have independent codes so you can give access to one and not the other.
