1. General Description
The LETIX Digital Web Tension Indicator continuously displays the true web tension either as a
percentage of total tension or in real engineering units.
The measurement of actual web tension is made by sensing, with strain gauge transducers (sometimes
referred to as 'load cells'), the force on a sensing roller caused by the tension in the web. The electrical
signal from the transducers is a combination of tension force and sensing roller deadweight.
The effect of the weight of the sensing roller is removed electrically, leaving the tension force signal only
to be displayed on the meter.
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 2mA maximum). It can be used as a remote display and/or as the input to a control
system.
The Indicator can accept full scale input voltages of either up to +/- 40 mV (foil strain gauges) or up to +/-
400 mV (semi-conductor strain gauges) for full display with selectable decimal point position and scaling,
and a zero offset for both positive and negative sensing.
