Water proofing - Import export

FLL-certified roof protection layer made of soft PVC for installation on non root-proof roofs, for forming a watertight and root-proof basin on green roofs with water accumulation and as water-proof and root-proof lining in planters.

The water pressure-proof UVC-SE sensors serve as robust, long-term stable measuring heads for the precise measurement of UV-C irradiances of low-pressure mercury lamps and amalgam lamps 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, the German national test authority. The integrated electronics produce a signal voltage that is transmitted to the PLC or panel meter RM-32, so that inferences are minimized. Operating voltage and output signal can be selected to match the measurement task or PLC interfaces.

The water-proof sensor UVX-SE serves as robust, long-term stable measuring heads for the precise measurement of UV irradiances in production lines, that have to be wet cleaned. The sensors are calibrated with traceability to the PTB (Physikalisch Technische Bundesanstalt, the German national test authority) and can be exposed to pressure of up to 10 bar. The sensors are available in eight spectral ranges and two measuring ranges. This allows the sensors to be optimally adapted for the application. The integrated electronics produce a signal that is transmitted to the PLC or panel meter, so that inferences are minimized. Operating voltage and output signal can be selected to match the measurement task or PLC interfaces. For small control tasks, the sensor UVX-SE can be connected to RM-32, which shows current irradiance on a 3.5-digit digital display and switches two relay contacts with adjustable warning and alarm signals.
