PMA 2102 UVB Detector for Outdoor Use

 

Biologically-Weighted UVB Detector for Outdoor Installation

The PMA2102 detector gives an accurate measurement of the biologically weighted ultraviolet radiation from sunlight or artificial light sources, also called sunburning UV radiation (SUV). Its spectral response follows closely the erythema action spectrum.

FEATURES

  • High sensitivity
  • Dynamic range 2*105
  • Excellent long term stability
  • Cosine corrected
  • NIST traceable calibration
  • Radiometric and biological units

APPLICATIONS

  • Meteorology
  • Agriculture
  • Environmental monitoring
  • Industrial control
  • Material testing
  • UV-B transmission measurements
  • Educational

> Detectors need to be used with a Radiometer

> Analog version of this detector can be used with any 0 to 5 VDC or 4 to 20mA recording device

The PMA2102 detector is designed to operate in outdoor environment. A built-in temperature sensor and compensation algorithm correct for the temperature coefficient of the UV sensor.

A Teflon diffuser assures an angular response close to a cosine function for incident angles up to 50 making it suitable for measurements of diffuse radiation (sky radiation), often the major component of solar UV.
