Abstract
A low voltage, compact measuring apparatus for measuring the weight of a material is disclosed which uses a PIN diode in conjunction with a low noise processing circuit to detect particle radiation emitted from a source, which source has its detection intensity affected by a material to be measured. A light blocking, particle radiation permeable material protects the PIN diode from detecting light radiation.
