What is the weighing instrument, what is its type and structure
Weighing instrument is a kind of sensor machine equipment, which can accurately measure the force of an object according to the load borne by the inspection bearing medium. The weighing instrument can convert the pressure from the medium into a relative electronic signal, and then achieve the purpose of accurate measurement. , Weighing instrument is a machine equipment that converts quality data signals into electronic signals that can be accurately measured. Before installing the weighing instrument, you should first consider the specific office environment where the weighing instrument is used. This is very important for selecting the appropriate installation of the weighing instrument. The natural environment of the weighing instrument application and whether the weighing instrument is in normal operation and The service life and its reliability are related to the safety factor. According to the conversion rules, the weighing instrument is divided into 8 types: optical, hydraulic, electromagnetic induction, capacitor, geomagnetic pole conversion method, vibration type, mobile phone gyroscope, resistor Types of strain force, etc. In the basic elements and evaluation methods, the performance indicators of the weighing instrument are different from the quality of the national industry standards, such as S-type weighing instrument, hanging wall weighing instrument, spoke weighing instrument, plate ring weighing instrument , Metal bellows type weighing instrument, bridge type weighing instrument, pole type weighing instrument, etc. The principle of the weighing instrument is to pull down and narrow the metal material heating wire in the supporting force function, and then the resistor is raised, that is, the metal material resistor changes with the strain force it bears. The weighing instrument is used to transfer the net weight data signal or The working pressure data signal is converted into the conversion equipment of the electricity consumption data signal. The construction principle of the weighing instrument is that the metal material resistor has the characteristics of blocking the flow of current. Generally speaking, the denser the metal wire, the greater the resistance value. When the metal resistor wire is stretched under external force, its resistance value will expand or decrease within a certain range. Therefore, if the metal wire (or film) is firmly adhered to the measured object, it will be When the object is telescopic under external force, the metal material resistor wire will expand and contract in proportion, and its resistance will change relatively. The weighing instrument will stick the metal material resistor strain gauge to the metal material weighing main beam for accurate measurement Net weight data signal. The polyurethane elastomer of the weighing instrument has a unique structure. It has two functions. The first is to bear the external force of the weighing instrument, and the external force creates a recoil to complete the relative static balance. The second is weighing. The polyurethane elastomer of the instrument can create a high-quality strain force field (area) to adhere to the area. The polyurethane elastomer of the weighing instrument is an ideal choice for the daily task of transforming the strain force data signal.
