A method for controlling charge accumulation on a mobile platform in a tank containing a non-conductive, energetic substance includes configuring the mobile platform to include at least an electrical power supply and a charge accumulation control system. The power supplied from the electrical power supply to one or more electrical power consumers associated with the mobile platform adds an electrical charge to the mobile platform. The charge accumulation control system controls an accumulation of the electrical charge on the mobile platform by one of: (i) reducing the supplied power and preventing an increase in the supplied power later while the mobile platform is inside the tank, and (ii) disengaging the electrical power consumer(s) from the supplied power and preventing a reengagement of the supplied power with the electrical power consumer(s) later while the mobile platform is inside the tank.

An optical probe includes an elongate hollow probe body, an optical window mounted at a distal end of the probe body for transmitting light therethrough, an ultrasonic transducer mounted within the probe body for applying ultrasonic vibrations to the optical window for cleaning the optical window, and one or more light guides located within the probe body for transmitting light through the optical window to a measurement region and/or for receiving light transmitted through the optical window from the measurement region. The ultrasonic transducer is located within the distal end of the probe body adjacent the optical window to transmit ultrasonic vibrations directly from the ultrasonic transducer to the window.

A process scope for monitoring, closed-loop and open-loop control of chemical and physical processes in the interior of explosion-proof containers and reactors during operation without interruption of the production and/or research processes. The device has an observation tube tip, an electro-optic or spectroscopic camera, a shock-proof housing with an electronic protection circuit, a lighting device, and image processing electronics. The tube tip does not have any ignition sources and is suitable for use in danger zones. Optical fibers are provided for transferring light from the lighting device to the tube tip and for the image transfer from the tube tip to the electro-optic or spectroscopic camera. A glass fiber data cable is provided for the transmission of image data from the camera to the data acquisition, system. By arranging the lighting and monitoring front windows laterally in the tube tip, parallax distance measurements can be made within the reaction vessel.
