  • the interactive casing can house and protect sensors only, actuators only, emitters only, in- struments only, or a combination thereof.

  • the casing, object of the present invention can consist of two bodies (an “instrument body” containing the instrument chamber for protecting sensors and/or actuators and a “door body” containing the door-chamber for the driving of the door) to facilitate the maintenance and the "in loco" installation of the entire spare parts or it can con- sist of a single body with two chambers (instrument chamber and door chamber) .
  • said body alone can represent an independent accessory, useful for being installed in and protecting industrial equipment, al- ready existing on the market for recording and measuring.

  • UV Ultra Violet
  • Both the wedged linear door and the revolving door prevent or limit the entry of water, oil, powder, metal sprays, chemical substances or other pollutants into the casing and open only for the time necessary for reading the sensors and/or for the action of the actuators.
  • the injection of gas or compressed air prevents or limits the entry of water, oil, powder or other pollutants into the casing: this is preferably obtained by the presence of an overpressure in both chambers and consequently, in case of separate bodies, it is advisable to have injection means also in the door-chamber .
  • the body or bodies which form the casings can be produced, for example:
  • the lightening is at its maximum when the casing must operate on the arm of a production robot.
  • the installation of robots allows the reading in very particular moments of a productive process and exploration in spaces which cannot often be reached with fixed instrumentations.
  • the box can be heavier when it has to work from fixed positions.

  • electro-valves and springs the use of an air overpressure inside the casing prevents the entry of powder, water vapour, oil-air and other aggressive chemical agents.
  • the gasket physically closes the door.

  • the lat- ter in the presence, for example, of a cloud of oil-air, have the defect of creating turbulence near the object being measured, modifying its properties.
  • the revolving door is able to avoid a possible drawback which could be created by a contact door with a gasket, such as a linear door.
  • a very long stop could cause the non-opening of the wedged door due to the adhesion between the gasket and the mobile section; in this latter case a button can be envisaged for the manual driving of the door after long stops, before the automatic and remote operation.
  • the instrument-chamber contains sensors of electromagnetic waves inside a cone of a certain opening
  • a spherical joint system or a system with horizontal coordinates (height and azimuth) can be used for the orientation of the casing.
