Summing boxes for hazardous areas

Critical weighing system components, Hardy stainless steel HI 6020 summing boxes distribute excitation voltage from up to 4 load cells and transfer their performance characteristics and weight signals to a Hardy weighing instrument. They feature electronic calibration that eliminates the need for test weights and an integrated technician that offers complete weighing system monitoring and troubleshooting. The boxes come with a variety of options, such as trim pots (for non-Hardy load cells) and a NEMA 4X enclosure in stainless steel, painted steel or fiberglass. Typical weighing applications include batching/blending, filling/dispensing, level-by-weight, inventory management and product inspection.
