LTM-BASE

The ROLAND LTM-BASE Thickness Gauging System is an easy-to-integrate system for determining thickness measured values during continuous operation. It was specially developed for high speed strip material, especially in press shops or band-coil processing systems.

The system is designed so that up to 5 measuring points can be statically operated, evaluated, displayed and stored either optionally or simultaneously.
The measurement is carried out without contact.

Datasheet LTM-BASE

LTM-BASE ● High performance measuring system for
Static Thickness Gauging - maximum 5 tracks.
Measurable material thickness: 0.05mm ... 8mm

LTM-S software

LTM-S (internal client) includes all necessary tools
for the operation, processing, presentation and provision
of the recorded thickness measurement values. LTM-S
is included in the scope of delivery of the Thickness
Gauging Systems LTM-BASE, LTM-SMART, LTM-MAXI
and LTM-ULTRA.
