N400 High Speed Tonnage Monitor

N400 Series High Speed Tonnage Monitor

N400 Series High Speed Tonnage Monitor

The N400 Series was designed specifically for high speed applications, canning operations, compaction presses and refractory presses. High and low limits can be manually adjusted with the N400. Thus, the operator can set the tolerance very close, which is ideal for high speed presses.

It is typically used with sensors and load cells for point-of-operation monitoring. The combination of monitoring and the fact that the N400 uses actual tonnage numbers for high and low limits (compared to benchmark systems), is important for this type of production. It allows you to have precise control of your press.
