Pneumatic Motor Drives

The staff of a plant does not always have the possibility to survey the interior of a process vessel through a sightglass on site. For these cases, remote observation by means of a camera linked to a control room is the optimal solution. A camera may, however, only record and transmit high-quality images if the product side of the sightglass disc is free of dust, condensate or crystal depots. The motor drives series WDP have been developed for such applications. The combination of a window wiper, a spraying device, a VIDEOLUX camera system and a light fitting and the motor drive unit ensures an optimal image quality at any time.

SERIES WDP:

- Pneumatic drive for use in hazardous and safe areas

- For ambient temperatures from –20 °C to + 20 °C (T6) or from –20 °C to + 40 °C (T5)

- Ex classification: Ex II 2 GD c IIC T6 / T5

- Speed adjustable by means of throttle valve

- Operating pressure of the unit sightglass / WDP: Depending on the dimensions of the sightglass disc with central bore hole
