A weighing cell for insertion into an associated receiving holder, a) wherein the receiving holder can be provided for arrangement in a machine intended for weighing tasks, and b) wherein the weighing cell has alignment elements (104, 105, 106) that are formed to cooperate with alignment elements (204, 205, 206) of the receiving holder, and c) wherein the weighing cell extends in a first horizontal direction, a second horizontal direction perpendicular thereto, and a third direction perpendicular to both directions (X, Y), d) wherein the weighing cell is formed to produce at least one releasable mechanical and electrical connection with the holder by inserting the weighing cell into the holder, and e) wherein alignment elements (105, 106) of the weighing cell in each case comprise at least one stop means which in the inserted state cooperates with at least one stop means that is formed in a manner complementary thereto and pertains to the alignment elements (205, 206) of the receiving holder so that the weighing cell occupies an exactly predeterminable relative position with respect to the receiving holder, characterised in that f) the weighing cell can be pre-positioned in the receiving holder, wherein it rests against a contact face of the receiving holder that functions as a stop acting in the direction, and wherein upon further displacement in the direction it reaches a stop acting in the X-direction, and g) the alignment elements (104, 204) of the weighing cell and of the receiving holder have guide elements that run in the direction and are formed so as to be complementary to each other in order to secure the weighing cell upon insertion into the receiving holder against twisting and/or lateral displacement transversely to the direction. a) wherein the receiving holder can be provided for arrangement in a machine intended for weighing tasks, and b) wherein the weighing cell has alignment elements (104, 105, 106) that are formed to cooperate with alignment elements (204, 205, 206) of the receiving holder, and c) wherein the weighing cell extends in a first horizontal direction, a second horizontal direction perpendicular thereto, and a third direction perpendicular to both directions (X, Y), d) wherein the weighing cell is formed to produce at least one releasable mechanical and electrical connection with the holder by inserting the weighing cell into the holder, and e) wherein alignment elements (105, 106) of the weighing cell in each case comprise at least one stop means which in the inserted state cooperates with at least one stop means that is formed in a manner complementary thereto and pertains to the alignment elements (205, 206) of the receiving holder so that the weighing cell occupies an exactly predeterminable relative position with respect to the receiving holder, characterised in that f) the weighing cell can be pre-positioned in the receiving holder, wherein it rests against a contact face of the receiving holder that functions as a stop acting in the direction, and wherein upon further displacement in the direction it reaches a stop acting in the X-direction, and g) the alignment elements (104, 204) of the weighing cell and of the receiving holder have guide elements that run in the direction and are formed so as to be complementary to each other in order to secure the weighing cell upon insertion into the receiving holder against twisting and/or lateral displacement transversely to the direction.
