SUVO Sensor (Open Channel)
The optional Purgo EnviroTech Model SUVO Sensor measures the relative UVC intensity of the germicidal 254nm wavelength within the UV Rack. The output from the UV sensor is processed by the PLC and the resultant, relative intensity is shown on an LCD display in %. This level is compared to set points established within the PLC to determine if the relative UVC has fallen to the minimum 
level required for proper treatment or is approaching the minimum level. Appropriate visual alarm indicators are activated by the PLC to inform the operator of the respective condition. This feature enables the operator to note when water quality has degraded or the UV lamps are approaching their end of useful life.
The semiconductor device that is used to detect the 254nm UVC is of a highly advanced composition that exhibits minimal UVC degradation over time. This helps to ensure the long term accuracy of the SUVO Sensor.
A more accurate representation of the average UVC field intensity within the UV Rack can be acquired by incorporating multiple, strategically positioned, SUVO Sensors within the multilamp arrangement of the UV Rack. This increases the effective UVC sensing area and provides a more accurate representation of the average UVC field intensity.
