Overview

The Senseca LPUVC01 is a radiometric probe that measures irradiance, defined as the radiant flux (W) passing through a surface divided by the surface area (m²), in the UVC spectral range (200 nm…280 nm). Thanks to the use of a new type of photodiode, the probe is blind to visible and infrared light. It is suitable for indoor applications that need constant radiometric monitoring.

The probe needs no external power supply. The photodiode current is converted into a potential difference through a resistor and read in mV with a voltmeter, and the irradiance value is calculated with the calibration factor marked on the probe housing. Each probe is individually calibrated, by measuring the irradiance coming from an Hg lamp at 254 nm. The output signal can also be amplified or converted into a 4…20 mA or 0…10 Vdc signal.
