When dispatching from the factory, earlier digital weighing sensor is demarcated and made it to have unified ISN output, ISN according to each sensor output carries out inverse operation in use, draw the weight that each sensor bears, weight to all the sensors adds up then, draw total weight, exactly because employing said method, the method that difference and common simulation weighing apparatus are averaged to signal, guaranteed that digital weighing sensor output valve at the scene is identical with output valve when the factory calibration, make electronic weighing system not need on-site proving, also can satisfy the requirement of 3 grades of scales.
As an ingredient of patent of the present invention, above-mentioned carrier designs according to actual conditions, can be the table top of weighbridge, and batch can etc. can bear the object of weight.
Major part as patent of the present invention, the concrete form of above-mentioned digital weighing sensor and structure are prior art, mainly be made up of elastic body, strainometer, fluid sealant, digital module and connection lead etc., this digital sensor was demarcated before dispatching from the factory, and made it unified output.
As the major part of patent of the present invention, above-mentioned indicating device has identical signal transfer protocol with digital sensor, and numerical code that can receiving sensor is also carried out computing and shown weight it.
The present invention can adopt different installation methods according to different sensor constructions: can not export the sensor that exerts an influence to sensor for erection stress, can adopt conventional directly fastening with bolt; Can export the sensor that exerts an influence to sensor for erection stress, must adopt the installation sleeve structure identical with the output when the factory calibration with the output that guarantees sensor, be that preferred described digital weighing sensor is provided with mounting hole, be provided with installation sleeve in the mounting hole, described digital weighing sensor is connected on the weighing apparatus basis by the bolt of passing installation sleeve.
For the output that further guarantees sensor identical with the output when the factory calibration, the carrying pressure head of sensor when carrying pressure head and the contact point of sensor should not change along with rocking of carrier, be to fixedly connected with carrier in described carrying pressure head upper end, described carrying pressure head lower end and digital weighing sensor are maintained fixed and contact.
The weighing apparatus basis generally be the requirement level and enough intensity arranged.As preferably, described weighing apparatus is fixed with built-in fitting on the basis, and described digital weighing sensor is installed on the built-in fitting.Described built-in fitting can adopt the steel plate of processing and regulating after the level.As preferably, this built-in fitting preferably carried out the steel plate of modifier treatment.
The present invention is owing to adopted above technical scheme, earlier digital sensor is demarcated and made it to have unified ISN output, ISN according to each sensor output carries out inverse operation in use, draw the weight that each sensor bears, weight to all the sensors adds up then, draw total weight, exactly because employing said method, the method that difference and common simulation weighing apparatus are averaged to signal, guaranteed that digital weighing sensor output valve at the scene is identical with output valve when the factory calibration, make electronic-weighing weighing apparatus not need on-site proving, also can satisfy the requirement of 3 grades of scales.
