Ultraviolet Rays Sensor UV-200

The sensor picks up and displays the ultraviolet rays that eyes is unable to perceive.
Because the sensor applies Sumita's ultraviolet to visible wavelength conversion glass, reliability is high, and it is the optimum sensor device for factory production line inspection.
It is possible to select the optimum sensor head for the wavelength, and operation is also simple.

  • This is optimum sensor device for factory production line inspection with high reliability.
    Ultraviolet to visible wavelength conversion glass is adopted, make it possible to observe continually and stably, even in high power ultraviolet rays.
  • Sensor head has wavelength selectivity for ultraviolet rays. (heat-resistant type)
    By applying sensor head that matches with wavelength, make it possible to observe more accurate.
  • Light guide has two types, heat-resistant type and free cut type.
    heat-resistant type : heat-resistant temperature+300℃
    free cut type : with 1m protection tube for tip
  • Operation is easy.
    When you push teaching button(or external input button) in beginning condition, intensity value is memorized in built-in memory, display value goes 100%.
    Setting threshold value is possible by 1% step of teaching value ratio.
    After input value goes less than threshold value, detecting output switches on. (intensity mode)
    When integrated value is between zero and setting value, detecting output is switched on. (accumulation mode)
  • Analog output is equipped as standard. Thus, it is applicable for controlling UV rays intensity and recordings.
