The water pressure-proof UVC-S sensor serves as a robust measuring head with photo diode output for UVC measurements in water disinfection and wastewater systems. The sensor can be exposed to pressure of up to 10 bar.
A long-term, stable high-sensitivity photo diode with a large active area of 1 cm² is used. This provides low noise and improved sensitivity, below 260 nm, compared to SIC sensors.
Superior corrosion resistance and long-term stability is also achieved through the use of appropriate materials. No aging is determined over a period of one year. The sensors are calibrated with traceability to the PTB (Physikalisch Technische Bundesanstalt, the German national test authority), the German national test authority. The absolute calibration is engraved on the sensor.
The sensor can be directly connected to the UV panel meter RM-31 via a shielded cable. The RM-31 works as a UV monitor and lamp control. The device displays the current irradiance on a 0% to 100% scale and also the lamp condition with three colored LEDs. Two alarms (warning and failure) are available.
