UV Power Monitor/Sensor
UV-300K

Ideal for continuous monitoring of output state of UV
UV sensor picks up and displays the ultraviolet rays that eye is unable to perceive. It is a device used for continuous monitoring of UV light intensity. Since SUMITA’s ultraviolet to visible wavelength conversion glass is used in UV-300K, its reliability is high, and it is an optimum sensor device for line inspection in production process. UV-300K enables detecting UV lamp’s deterioration and lighting failure.

SUMITA’s UV sensor/monitor UV-300K features:

  • Highly durable glasses are used for converting ultraviolet to visible light wavelength
  • Monitoring wavelength range: 170- 380 nm
  • Feedback UV lamp’s light intensity variance
  • Two operating modes provided: light intensity mode and integration mode
  • Analog voltage output: voltage (1 - 5 V) and current ( 4 – 30 mA)
  • Sensitivity setting by teaching
  • Answer-back output function
  • The optimum sensor head selectable for the wavelength employed
  • Simple operation

Applications

  • Semiconductor manufacturing devices
  • Disinfection and sterilization
  • UV curing
  • Lighting
  • Printing
