Radiation protective cover for temperature sensors

The invention relates to a radiation shelter for temperature sensors with several, essentially the same Shaped and coaxially spaced, upwardly convex shells

Huts of this type are used instead of the earlier English huts for temperature observation · For many purposes however, it is desirable to observe a further component in addition to the temperature which has the property of The atmosphere at the place where the hut is set up has a say, in particular ZcB. the damp.

The invention is based on the object of a radiation protection hut of the type mentioned at the beginning in such a way that they are also suitable for the reception of others,

; ¹¹¹ O'ti, Ι

if necessary ζ α sät zl ich sr instruments are suitable;

To solve this problem, a radiation shelter of the type mentioned is characterized in that the upper Part of the hut as a chamber connected to the lower interior of the hut to accommodate additional instruments is trained. In a preferred embodiment, the radiation protection shelter is provided by a topmost, inverted cup-shaped hood marked. After The invention is also provided that the hood down to the central area through a disk with a central opening is completed. According to a further feature, the disk is made from a body that is reinforced in the edge area Cast light metal on which the hood is detachably attached, e.g. by means of a bayonet lock or head screws

The shells and the hood of the hut according to the invention can be made of brass or zinc sheet or plastic. In a preferred embodiment, the shell and the hood are made of aluminum or an aluminum alloy and are anodized on the outside in natural color.

The hut according to the invention accordingly has a space in the upper part that can accommodate an additional instrument allowed. The hood with the baseplate of the chamber simultaneously takes on the task of otherwise closing a double shell provided for a radiation hut.

Further advantages and features of the invention emerge from

711901026.8.71 " ⁵ "

the claims and from the following description and the drawing, in which a preferred embodiment of the invention is explained and shown, for example.

The only drawing figure shows a side view of a radiation protection hut according to the invention, with individual parts are broken away or shown in section

A radiation shelter according to the invention has a plurality of essentially identically shaped and coaxially rdneten at equal intervals, upwardly convex shells 10 which are open in the middle. The bowls are arched or frustoconical and end on a short, cylindrical skirt at the edge.The middle opening of each bowl is surrounded by an annular flange 12.The number of bowls is determined by the length of a sensor 24 to be placed in the radiation shelter, the lower one of which End should be above the annular flange 12 of the bottom shell "

To protect against lateral scattered radiation, at least in the lower area of the radiation shelter in the spaces between between successive shells frustoconical, downwardly convex shells arranged, the outer opening diameter is chosen so that between the outer upper edge of each shell 14 and the reaching away over the edge Shell 10 remains a gap for air to pass through · You shells 14 lie with a substantially equal size Ring flange 16 on the ring flange 12 of the respective underlying shell 10The shells are made with spacing

pieces 20 lined up on a threaded rod at the end, the one on the outside of an upper and lower Holding plate 26 and 18 is attached by screws. Three or four rods 28 are provided for a steady line-up.

On a rod 28 is a pin 22 for mounting the bottom Hut attached to a standard stand

The top plate 26 is a light alloy casting with a reinforced rim. A cup-shaped hood 30 is releasably attached to this edge with cap screws 32. The head screws engage in radial bores in the edge of the plate 26. The space in the hood 30 is so large that instead of the usual temperature sensor, a sensor with an additional instrument 25 can be arranged, which is connected through the hole in the disk 26 with the ventilated space below the radiation shelter. In particular, a humidity transmitter can be arranged in the hut according to the invention, which has a sensor part 24 and an electronic part 2.5. Cables are not designed in this way for the sake of simplicity.

The Schalr.i 10 and 14 and the hood 30 are made in the illustrated embodiment sr.s on the outside anodized aluminum. The surfaces of these parts facing the janenraum are provided with a matt black coating. Instead , it is also possible to manufacture the shells from a plastic with a low heat capacity, the outside of which is preferably coated with a radiation-repellent coating, e.g. covered with a bare metal foil on the outside.
