Radiometric sensors

radiometric sensors for precise uv measurements
spectral sensitivity for UV sensors
Spectral sensitifity for broadband UV radiometric sensor and light sensors

Our radiometric sensors accurately measure the UV irradiance or illuminance with the RM-12 or RM-22 radiometer and the UV-MAT dose control. The built-in diffusers ensure the cosine correction that is required for non-vertical irradiation.

The sensors are calibrated with traceability to PTB (Physikalisch Technische Bundesanstalt, the German national test authority); after being calibrated, they are supplied with a factory calibration certificate. Excellent long-term stability is achieved through the use of appropriate materials. Of course, a repair and spare parts service is available for many years.

The integrated electronics produce a signal voltage that is transmitted to the radiometer. Various sensors can be used with a radiometer by means of internal electronics.

The sensor on the RM-22 is identified by additional memory, which also contains the calibration and the date of manufacture. Our range includes eight spectral ranges and four measuring ranges for the sensors.

This allows the radiometric sensors to be optimally adapted for the application.
Sensors to evaluate the biological effects of irradiation are also available. Going further if necessary, in special cases, the sensors are splash-proof in accordance with IP65 and available with advanced measuring and spectral ranges.
