UV Sensor "TOCON-Probe"
Minature UV Sensor
1/3General Features

The “TOCON-probe” is a miniature UV sensor with a male threaded body (M12x1) with a0…5 V voltage output. It works with an amplified UV photodetector from the sglux“TOCON”-series. The sensor will be configured upon individual customer’s requirements
which are clarified within the order process. Configurable parameters are themeasurement range and the spectral responsivity. The determination of the individual
dynamic range needs customer’s assistance, e.g. information about the source to bemeasured and a typical distance between the sensor and the source.
This sensor is not adjustable. However, a PTB traceable determination of the sensor’s individual sensitivity available.
Figure 1 shows the different options regarding the spectral responsivity of the sensor. Our sales team is happy toassist our customers selecting the best suitable responsivity for the specific application. Alternatively, technicalreports and selection guides are available on our website providing further assistance.

spectral responsivity selection options
Figure 1 shows the available spectral responsivites. Table 1 shows the position of the peak and the 10% of maximun
margins. For UV measurement, by default, unfiltered broadband SiC is applied. If a UV source also emits radiationthat must not contribute to the sensor’s signal (e.g. UV medium pressure lamps used for water or air purification that
also emit non germicidal UV radiation) a filtered SiC sensor (UVC, UVB or UVA only) is to be selected. For measurementof radiation above 390nm GaP based detectors are used.
