UV Sensor "UV-Radial"
Waterproof side looking UV sensor
1/4General Features

The „UV-Radial“ is a waterproof side looking UV sensor. A typical application ismonitoring of UV lamp bundles that are aligned radial around the sensor. The sensor issuitable for operation in a cladding tube or directly in water. It will be configured upon
individual customer’s requirements which are clarified within the order process.
Configurable parameters are the signal output type, the measurement range and thespectral responsivity.

The signal output is configurable as a 0…5V or 0…10V voltage output or a 4…20mA current loop. Digital output
sensors are available with a MOD bus, a CAN bus or a USB interface. The determination of the individual dynamic
range needs customer’s assistance, e.g. information about the source to be measured and a typical distance between
the sensor and the source. A PTB traceable calibration can be ordered. Figure 1 shows the different options regarding
the spectral responsivity of the sensor. Our sales team is happy to assist our customers selecting the best suitable
responsivity for the specific application. Alternatively, technical reports and selection guides are available on ourwebsite 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.
