Basic definition and function of weighing instrument technical parameters

Abstract: The basic definition and function information of the technical parameters of the weighing instrument are provided by the excellent manufacturers of flowmeters and flowmeters. 1. Rated load: the maximum axial load that the sensor can measure within the specified technical index range. But in actual use, generally only 2/3~1/3 of the rated range is used. (2) Allowable use load (or safe overload): the maximum axis allowed to be applied by the load cell. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the basic definition and function of the technical parameters of the weighing instrument. 1. Rated load: the maximum axial load that the sensor can measure within the specified technical index range. But in actual use, generally only 2/3~1/3 of the rated range is used. (2) Allowable load (or safe overload): the maximum axial load allowed by the load cell. Overwork is allowed within a certain range. Generally 120%~150%. (3) Limit load (or limit overload): the maximum axial load that the load cell can bear without making it lose its ability to work. This means that the sensor will be damaged when the work exceeds this value. (4) Sensitivity: the ratio of the output increment to the applied load increment. Typically mV of rated output per 1V of input. (5) Nonlinearity: This is a parameter that characterizes the accuracy of the correspondence between the voltage signal output by this sensor and the load. (6) Repeatability: Repeatability indicates whether the output value of the sensor can be repeated and consistent when the same load is repeatedly applied under the same conditions. This feature is more important and can better reflect the quality of the sensor. The description of the repeatability error in the national standard: the repeatability error can be used to determine the maximum difference (mv) between the actual output signal values ​​of the three measurements at the same test point at the same time as the nonlinearity. (7) Lag: The popular meaning of hysteresis is: when the load is applied step by step and then unloaded in turn, corresponding to each load level, ideally there should be the same reading, but in fact it is consistent, the degree of inconsistency is measured by the hysteresis error. represented by an indicator. In the national standard, the lag error is calculated as follows: the maximum difference (mv) between the arithmetic mean of the actual output signal value of the three trips and the arithmetic mean of the actual output signal value of the three upstrokes at the same test point. (8) Creep and creep recovery: It is required to check the creep error of the sensor from two aspects: one is creep: the rated load is applied without impact for 5-10 seconds, and 5-10 seconds after loading Take readings and then record the output values ​​sequentially at regular intervals over a 30-minute period. The second is creep recovery: remove the rated load as soon as possible (within 5-10 seconds), immediately read within 5-10 seconds after unloading, and then record the output value at certain intervals within 30 minutes. The technical parameters of the weighing instrument The technical index unit is as follows: Multiple input 0-20mV single output 0-20mV accuracy≤±0.1%F.S Power supply voltage 12, 24VDC Working temperature -20~85℃ Protection class IP65 The above is the whole content of this article.
