The Digital Signal Processing Unit (UTN) is a smart box that processes locally on the machine some signals such as weight, speed, belt deviation, belt slipping and rotation control.
It is usually attached to the frame of the machine and includes:
- A microcontroller DSP (Digital Signal Processor) for digital signal treatment and filtering,
- A digital strain gauge converter, OFFSET and GAIN adjustable by buttons,
- 4 connectors for 4 strain gauges sensors mounted in parallel,
- 4 digital inputs for measuring speed , rotation control and band offset,
- 1 analog output.
Communication with MiniSmart controller is realized by an RS 485 link.
