紫外線二極體轉換器 Photodiode Transducers
  • Photodiodes convert incoming electromagnetic radiation into electrical charge carriers. If photodiodes are short circuited an electrical current (photocurrent) proportional to the incident radiation intensity (number of photons per second) is induced. These photocurrents are generally small and cover the range from femtoampere to microampere . Signal transducers transform this weak photocurrent to robust standard signals for reliable data transmission and simple data acquisition.

  • The voltage which is present on the open pins of a photodiode without a short circuit (photovoltage) can be easily measured with a voltmeter but is strongly non-linear correlated to the radiation intensity and thus not very useful for the measurement thereof.

  • The transducers developed by sglux employ transimpedance amplifiers which short the photodiodes and therefore provide a linear relationship between the incident radiation intensity and the output signal.

  • We offer analogue transducers with different voltage output.

  • Furthermore we produce digital transducers which convert the photocurrent into digital representation transmitted to a computer via USB (Digiprobe, SGCD4). These transducers offer an increased dynamic range compared with the analogue transducers.

  • To control industrial UV applications our SENSOR MONITOR 5.0 supports multiple functions such as limit control, dosage control, lamp monitoring.
