Web tension measurement and indication
%%IMAGE%%A recent addition to the CMC family of web tension products is the panel mounted Letix indicator unit.
The LETIX indicator uses high specification A/D and D/A converters, power supply, and a bright LED digital display, all housed in a standard DIN size case. The LETIX features as standard a transducer bridge supply excitation of 5v (or 10v) DC, an independently scalable digital display and an isolated analogue output (0 to +10V at 2 mA maximum). It can be used as a remote display and/or as the input to a control system.
