The multihead weigher is a kind of sensor equipment, which can accurately measure the force of the object according to the load borne by the test bearing medium. The multihead weigher can convert the pressure from the medium into a relative electronic signal, and then achieve the purpose of accurate measurement. A weigher is a device that converts quality data signals into electronic signals that can be accurately measured. Before installing the multihead weigher, you should first consider the specific office environment in which the multihead weigher is used. This is very important for selecting the appropriate multihead weigher to install. Whether the application environment of the multihead weigher and the multihead weigher are all normal operation and use period and its availability Reliability and safety factor are related. According to the conversion rules, multihead weigher is divided into 8 types: optical, hydraulic, electromagnetic induction, capacitor, geomagnetic pole transition method, vibration type, mobile phone gyroscope, resistor strain force type, etc. In the basic elements and evaluation methods, the performance index of multihead weigher is different from the quality among national industry standards, such as S-type multihead weigher, cantilever type multihead weigher, spoke-type multihead weigher, plate ring multihead weigher, metal bellows type multihead weigher multihead weigher, bridge type multihead weigher, pole type multihead weigher, etc.
The principle of the multihead weigher is to stretch and narrow the metal heating wire under the support force function, and then the resistor is raised, that is, the metal material resistor changes with the strain force it bears. The multihead weigher is used to measure the net weight data signal or working pressure. A conversion device that converts data signals into power consumption data signals. The construction principle of multihead weigher is that metal material resistors have the characteristics of blocking current flow. Generally speaking, the denser the metal wire, the greater the resistance value. When the resistor wire is retracted under external force, its resistance value will expand or decrease within a certain range. Therefore, if the wire (or film) is firmly adhered to the object to be measured, it will be When it is retractable, the metal material resistor wire will be retractable proportionally, and its resistance value will change relatively. The multihead weigher sticks the metal material resistor strain gauge on the metal material weighing main beam to accurately measure the net weight data signal. The polyurethane elastomer of the multihead weigher has a unique structure. It has two functions. First, it bears the external force of the multihead weigher, and creates a recoil force with the external force to complete the relative static balance. Second, the polyurethane of the multihead weigher Elastomers are capable of creating a high quality strain force field (region) to adhere to the region, and the multihead weigher's polyurethane elastomers are ideal for the daily task of performing strain data signal transformation.
