摘要：
The technology produces a very low profile, low physical weight load cell with no temperature or hysterisis effect. An 8,000 kg transducer is 50 mm**2 by approximately 12 mm thick and only grams in weight. The intensity of the output beam is determined by a Pin Diode, which converts light intensity to voltage in an opamp feed back arrangement. With the Pin Diode in reverse bias the diode leakage current is linearly dependent on light and the output voltage is also a linear function of the light intensity.
