LS Series Tonnage Monitor

LS Series signature based tonnage monitor

LS Series Signature Based Tonnage Monitor

The PressWatch LS (Load Signature) Series is one of the most advanced and complete production monitors on the market today. The LS Series provides tonnage and signature features that help ensure press, die and part protection.

The operator interface is a computer screen that provides color signatures to be displayed right at the press. Enveloping and Critical Curve monitoring (CCM) are part of the standard signature software.

We also provide a solution if you are interested in combining die protection and programmable limit switches (PLS) with your LS Series tonnage monitor.
