Provided is an electronic balance that enables a user to recognize the magnitude of disturbances in real time. An electronic balance (1) whose natural frequency is known, includes a load measurement mechanism (4) configured to detect weighing data (Zn), and an arithmetic processing unit (8) configured to perform arithmetic processing by using the weighing data (Zn), wherein the arithmetic processing unit (8) extracts a vibration component (Fr) of the natural frequency from the weighing data (Zn) detected by the load measurement mechanism (4) and displays the vibration component (Fr) of the natural frequency. By using the vibration component (Fr) of the natural frequency as an index of disturbances, it becomes possible to recognize in real time the magnitude of the disturbances during weighing.

Aweigh module with a load-receiving portion, a fixing portion, and a parallel guide portion also has a lever system with a first lever and a second lever. An additional portion of the load-receiving portion extends towards the fixing portion. An extension of the fixing portion extends towards the load-receiving portion. A first end of the first lever is connected by joints to the additional portion and the extension portion. A first end of the second lever is connected by joints to the second end of the first lever and to the extension portion. All joints are of a thin sheet structure. The second end of the second lever is configured for connection to a magnetic system. The weigh module is manufactured integrally. The use of the structure according to the present invention can meet design requirements of large range and small size of sensors.

The invention is a guitar hanger rack that comprises a piece of metal (or other rigid material) that is bent and notched at one end and has a curve-shaped cradle at the other bent end. This rack is designed to hold an instrument—such as an electric or acoustic guitar (or other similar type instrument that has a strap button on one end and a neck on the other). The notched end holds the strap button and the other curved cradle end holds the neck of the instrument so that it may be hung from a wall or ceiling. The purpose of the invention is to allow for the display of the instrument at multiple angles and in a manner that will not affect the finish of the instrument.

A weighing sensor is provided for an electronic balance. A weighing unit of the weighing sensor has a load-receiving portion, a fixing portion, and parallel guiding members that connect the load-receiving and fixing portions A lever, with a first end connected to the load-receiving portion, is located between the parallel guiding members and the fixing portion. A lower portion of a photoelectric position limiting block is connected to the fixing portion, and an upper portion thereof has a limiting structure. A tail end portion of a second end of the lever is disposed in the limiting structure, limiting its deviation. The photoelectric position limiting block has a photoelectric position sensor and a stop structure for limiting deviation of the tail end portion.

A magnetic suspension thermobalance based on quick photothermal heating comprises a sealed container, a reaction tank, a magnetic suspension device, a laser displacement monitoring component, a photothermal heating component and a photothermal heating component displacement device. A method comprises following steps: weighing a testing sample and adding same into the reaction tank; putting the reaction tank into the sealed container together with a magnetic suspension float; causing the magnetic suspension float to float in the sealed container; introducing gas into the sealed container; measuring the real-time position of the magnetic suspension float, and causing same to a measurement zero point; heating the reaction tank; maintaining a heating beam on the reaction tank; measuring the temperature of the testing sample in the reaction tank; and recording the displacement of the magnetic suspension float, and converting said displacement into mass.
