1 Scope

1.1 This procedure applies to the type identification (or prototype test) of the load cell (hereinafter referred to as the sensor), the first inspection Determination and subsequent verification. 1.2 This procedure specifies the main static metering performance and static assessment methods for load cells used in quality measurements. This procedure is to provide the metrology department with a uniform method of determining the metering performance of the sensors used in the controlled metering device. 1.3 This procedure considers several errors of the sensor together, and characterizes the characteristics of the sensor with the allowed error envelope. That is to say, the corresponding error limits are not specified for a given characteristic (such as nonlinearity, hysteresis, etc.), but are considered as poles. The entire allowed error envelope of the limiting factor. Using the concept of error envelopes gives us the same results Each factor that contributes to the overall measurement error can be balanced. Note. The error envelope can be defined as the curve that provides the maximum allowable error bound (see Table 5), which is within the measurement range. Load function (mass). The specified comprehensive error can be positive or negative and includes nonlinearity, hysteresis and spirit. Sensitivity temperature effects. 1.4 Meters used in conjunction with the sensor and giving a quality indication are not included in the scope of this regulation.

2 Terms and definitions

The terms and definitions most commonly used in the sensor field are given below (see 2.6 for some definitions) The terms used in this protocol are consistent with the basic terminology of international metrology and the terminology of legal metrology. For the convenience of this For the application of the procedure, the relevant definitions are given below. To help locate the corresponding definitions, the index of all defined terms is published as a separate form at the end of this procedure. tail. 2.1 General terminology 2.1.1 applied load (aplicationofload) 2.1.1.1 Compression loading The compressive force exerted on the sensor. 2.1.1.2 Pullloading (tensionloading) The tensile force exerted on the sensor. 2.1.2 Load cell (loadcel) After considering the influence of the point of gravity acceleration and air buoyancy, by converting the measured mass-- Another force sensor that measures - the output signal to measure mass. 2.1.3 Sensors with electronic circuits (loadcelequippedwithelectronics) A sensor that uses an electronic component that identifies its own function.
