Description

The UV-A sensor is built around a UV sensitive Schottky photodiode. The diode produces a current proportional to the UV intensity. The signal from the diode is amplified through a transimpedance amplifier and sent to the output.

Technical specifications:

  • Measuring range: 0 .. 25 W/m²
  • Accuracy 0.5 °C (typical)
  • Sensitivity range: 220 nm .. 370 nm with 10% sensitivity, 265 nm .. 365 nm with 50% sensitivity
  • Maximum sensitivity: 352 nm
  • Angle tolerance: 5°
  • Maximum sample frequency: 100 kHz (CoachLab II+, WiLab) / 1 MHz (VinciLab 2)
  • Warranty: 3 years

All technical specifications of the UV-A sensor are described in the product manual, see downloads.

Examples of experiments:

  • Measure the UV intensity as a function of time throughout the day
  • Measure the UV transmittance of various sunglasses and regular glasses
  • Measure the UV transmittance of fabrics, both wet and dry.

The UVA sensor can be directly connected to analog BT inputs of the CMA interfaces.
