These sensors are appropriate for the monitoring of radiation intensity of UV lamps in accordance with the DVGW guideline W 294 (10/97) and the ÖNORM M5873-1 standard (03/2001) respectively. They are designed to be installed in the FUV 38 measurement window if used in a water reactor.

Main features are:

• SiC-based sensor; therefore unaffected by daylight and only sensitive to UV light
• UV-C filter already integrated
• Probe body in stainless steel, insertion area 20 x 59 mm diameter, overall length 73 mm, with collar and groove for ”O” ring 18.77 x 1.78
• Entry window for UV: ∅ 12.0 mm; angle of opening 30° (DVGW), 160° (ÖNORM)
• Operating temperature: 0 to +60°C; 100°C for brief periods, storage temperature: -20 to +70°C
• Standard version has PG7 screw cable fitting with kink guard and 5 m cable
• Electronics as per DVGW standard or Ö-norm already integrated
• Option A1 (DVGW): sealed and watertight with a window admitting UV radiation, pressure resistant up to 1 bar
• Option A2 (ÖNORM): as A1 but with additional diffusion screen below the window. Please note: Both types are only pressure resistant up to 16 bar overpressure and for short time down to 1 bar sub-atmospheric pressure if installed with the measurement window FUV 38.
• Option C: Series 763 flanged plug, watertight to IP65 when screwed in, a suitable Z1G connector cable (5 m of 5-pole cable with open end) is to be ordered separately
• Option Y1: voltage output 0 – 2V DC (4,5 V DC max.), supply voltage 5 - 24 V DC, stabilised
• Option Y2: current output 4 - 20 mA, supply 24V DC, apparent ohmic resistance 500 Ohm max.
• Standard calibration Emax=50 W/m² or 100 W/m² equivalent to 2V (Option Y1) or 20 mA (Option Y2), customised calibration upon request
• On request it is possible to supply this type of sensor in compliance with the latest (04/2003) DVGW proposal or the ÖNORM M5873-2 of 06/2002.
• A value-for-money alternative is to order the sensor without integrated electronics, but then will not comply with the DVGW guideline or the ÖNORM anymore.
