The signal-monitor DUV 3.51 in combination with UV probes is conceived for the supervision of UV radiation sources. The monitor is designed for the installation into switch boards. The front panel contains three status LEDs, which depict the UV irradiation intensity that is recorded by the sensor. The analysis takes place in the gradations of > 70%; 50 ...70% and <50%. Optionally, the device can be equipped with a second switching output (changeover switch Rel 2), which is assigned to the range of 50 ... 70% of the irradiation intensity. The adaptation to the characteristic measurement range is fulfilled by the use of an adjusting device with an LED signal of "110%", which is accessible from the back.
