The TCD030 is a controller for controlling the tension of a web at the unwinder or winder, without using a tension sensor. The roll diameter is calculated by using a signal from a gate generator mounted on the winding/unwinding reel, and a control signal corresponding to the change in the roll diameter is delivered.
- Non-contact detection of roll diameter
The roll diameter is detected without any contact being made using a gate generator attached to a winding/unwinding reel. Therefore, the material is not exposed to damage.
- Easy to operate
It is operated just by setting the roll radius and the web thickness.
- Stop output circuit incorporated
A stop output signal is generated when stopping an unwinder. The reel is stopped without slackening the web.
- Applicable to various brakes/clutches
It is available with voltages of 0 to 10V and currents of 4 to 20 mA for control outputs. Combined with a converter, it can control an electromagnetic brake/clutch or an air brake/clutch.
- Applicable to very thin webs as well as to very thick webs
The web is available in thicknesses of 1 µm to 9.99 mm.
