Bel-2000 Gen II - Theory
The Bel-2000 analyzes the digital wave-shape generated by the impulse hammer when it is tapped against a roll of wound material. The force of the impact is captured by a transducer in the Bel-2000 hammer. The force and the duration of the impact varies with the hardness of the material. When a roll of material tapped, the force signal from the hammer rises from zero to a maximum peak value and then returns to zero. The shape of that wave is used to calculate the hardness value, called RHO.
The Bel-2000 hammer produces an analog signal that is digitized by the system microprocessor using an analog-to-digital converter (ADC).
