FIELD: construction industry. ^ SUBSTANCE: channel has chamber for strain gauge located in it and a sealing cup. Chamber provided for gauge is located in channel section, approximately in the middle and in area of edge of sealing channel. From area of channel edge, near passage from edge to chamber with gauge, but being spatially separated from chamber with gauge, near chamber with gauge there drawn immediately from edge area is sealing cup which protrudes outwards corner-wise to the edge and beyond external circuit of chamber with gauge in direction perpendicular to the edge. ^ EFFECT: improving reliability, sensitivity of response to jammed thin objects, and improving sealing. ^ 4 cl, 2 dwg |
