Load cell A force sensor used on a scale. The principle of resistance strain gauge weighing sensor, which can convert the gravity acting on the measured object into a measurable output signal in a certain proportion. The performance indexes of load cell mainly include linear error, hysteresis error, repeatability error, creep, zero point temperature characteristic and sensitivity temperature characteristic.

In the traditional concept, load sensor is a general term of load sensor and force sensor, and its metrological characteristics are evaluated by single parameters. The old national standard combines the two sensors of "weighing" and "force measurement", which are applied objects and use completely different environmental conditions, into one consideration, and does not distinguish between test and evaluation methods. The old national standard has 21 indexes, all of which are tested at room temperature; The accuracy level of the weighing sensor was determined by the maximum error of the six indexes of nonlinearity, hystereation error, repeatability error, creep, zero point temperature additional error and rated output temperature additional error, which were expressed by 0.02, 0.03 and 0.05 respectively.

A force sensor used on a weighing instrument. It can convert the gravity acting on the measured object into a measurable output signal in a certain proportion. Considering the influence of gravity acceleration and air buoyancy on the conversion, the performance indexes of the load cell mainly include linear error, hysteresis error, repeatability error, creep, zero point temperature characteristic and sensitivity temperature characteristic. In various weighing and mass measurement systems, the comprehensive error is usually used to bring the comprehensive control sensor accuracy, and the comprehensive error belt is linked with the weighing instrument error belt (Figure 1) in order to select the weighing sensor corresponding to a certain accuracy weighing instrument. The International Organization of Legal Metrology (OIML) stipulates that the error band δ of the sensor accounts for 70% of the error band Δ of the weighing device, and the sum of the linear error of the weighing sensor, the hysteresis error, and the error caused by the effect of temperature on the sensitivity in the specified temperature range cannot exceed the error band δ. This allows the manufacturer to adjust the individual components that make up the total measurement error to achieve the desired accuracy.
