The LS-ZT (Load Signature) Series is one of the most advanced and complete production monitors on the market today.
The LS-ZT 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.
