PWi Presswatch Forging Tonnage Monitor
Cost-Effective Full Featured Tonnage Monitor
The PWi Presswatch Forging instrument monitors multiple press tonnages during the forming of a single part. The forming
tonnage for up to four unique die stations can be displayed and each station has it's own set of tonnage limits.
Each set of tonnage limits is based on a benchmark value unique to the station using the convenience of AUTO-SET.
The PWi Presswatch Forging monitor displays the forming tonnage for each station sequentially. Station #1 shows the tonnage
developed in the Buster operation. Station #2 shows the tonnage that is generated in the Blocker operation and so
on up to four stations. Once the sequence is completed, the forging monitor assumes that a new part is starting
and returns to Station #1 again.
Time based (standard) and resolver based (optional) tonnage signatures
are viewed on the LCD screen, along with tonnage limit settings, alarm history, job storage, deviation and more.
