An apparatus for sensing an elastic deformation of a hollow element, wherein the apparatus comprises at least one sensor that is arranged in a watertight capsule which is connected in a watertight manner to a connector device comprising at least one watertight electrical connector that is electrically connected to the at least one sensor, the at least one watertight electrical connector forming a first waterproof barrier of the connector device between an outside of the watertight capsule and the at least one sensor, and wherein the connector device comprises at least one further waterproof barrier that is formed between the first waterproof barrier and the at least one sensor.

A weighing mechanism (1) includes: a hopper (105) configured to store an article; a hanger (2) on which the hopper is hung; a mass weighing instrument (3) configured to weigh the article stored in the hopper; a connection member (4) that connects the hanger and the mass weighing instrument; a main body member (6) having a through hole (5) through which the connection member penetrates; a diaphragm (7) that connects an outer edge of the connection member and an inner edge of the through hole of the main body member; and a waterproof cover (8) that covers at least part of the through hole between the diaphragm and the hanger. The waterproof cover is detachably attached only to the hanger among the main body member and the hanger.

A windshield for a balance which has a door that can be automatically opened and closed or half opened and half closed is provided. The windshield includes doors to which air cylinders are joined as driving means, sensors for monitoring movements of the doors, pressure sensors configured to monitor a pressure of air to be supplied to the air cylinders of the driving means, and a control unit configured to stop an air supply to the air cylinders when a pressure of air monitored by the pressure sensor exceeds a predetermined value. Stoppers are disposed on movement paths of the doors to block movement, and when air pressure inside the air cylinder increases to the predetermined value due to contact with the stopper, the door stops. The door can be freely fully opened and half-opened according to the position of the stopper.

Provided is a windshield for a balance, for which opening and closing doors of the windshield are smoothly moved without wobbling, dust or the like is unlikely to accumulate on the part of guide rails that guide the opening and closing doors, and cleaning is easy. Upper portions of the pair of opening and closing doors of the windshield are respectively suspended by upper frames provided along respective side portions of an upper surface door, and the opening and closing doors are reciprocated by air cylinders by being guided by guide rails each formed of a horizontal portion and a vertical portion. On the respective horizontal portions, projections that restrict lower ends of the respective opening and closing doors from being displaced in separating directions from the vertical portions are provided along movement paths of the respective opening and closing doors.

A sensing and digital display type weighing and code scanning integrated machine with a damping and dust-proof smart case includes a case device. A weigher is placed at an upper end of the case device. A code scanning device is fixedly connected to the upper end of the case device. The case device includes a case, a guide hole, a threaded hole, a through groove, a groove, a fan, a case door, a magnet, a guide rod, a first spring, a host base, a first clamping groove, a computer host, a filter cartridge, a circular groove and an efficient filter screen. The case door is hinged to the case. The magnet is fixedly connected to the case door. The guide rod is slidably nested in the case. The host base is fixedly connected to an upper end of the guide rod. The computer host is clamped in the host base.
