摘要： The assembly has a vibrating finger (110) integrated with a mast (120) in a transversal manner with respect to air flow and extending out from the mast. A cooling system comprises of an air circulation channel connecting air inlet openings and air outlet openings provided on the finger, where channel circulates the air in the finger to cool the finger.

摘要： The sensor has a core (1) conductor extending at interior of a conductive sheath (2). The core and sheath are separated by a material with positive or negative temperature coefficient. The sensor has a wire (4) made of a material with positive or negative temperature coefficient extending on the sheath and separated from the sheath by an insulating material. The core, sheath and the wire are linked by a connection unit.

摘要： The appts. comprises a probe (1) attached to a flexible measuring tape (2) coiled in a support mounted at the top of the tank in which liquid level is to be measured. The probe (1) consists of an enclosure (100) containing a sensing element (200) which is a metallic wave guide with four sections. Mechanical vibrations at a predetermined frequency (fi) are initiated in the sensing element (200) by a transducer (201) driven by electronic circuits. The transducer detects changes in the pattern of reflected vibrations when the lower face (208) of the sensor makes contact with the surface of the liquid.

摘要： The detector for detecting the presence of a liquid comprises: a) a metal waveguide having a solid cylindrical top first portion of relatively small section with an outside diameter having a first value d1, which first portion is fixed on a support, a cylindrical rigid bottom second portion whose outside diameter has a second value d2 greater than the first value d1, which second portion extends the first portion downwards and is connected thereto by a short linking portion; b) transducer means disposed in the vicinity of the top portion of the waveguide; and c) electronic processing means. The value of the frequency at which the transducer means are excited is selected in such a manner that acoustic wave trains propagate in the cylindrical first portion at the group velocity of low frequency waves, and propagate in the cylindrical second portion at the minimum group velocity corresponding to the point of inflection in the curve of phase velocity as a function of frequency.
