Namely, the weighing accuracy is ensured according to the feedback of the environmental parameters of the temperature and humidity sensors, and the parameters of the sensors are intelligently judged to carry out compensation correction.
The specific principle is as follows:
the core element of the high-precision weighing sensor is a resistance strain gauge, and the performance of the high-precision weighing sensor mainly depends on two aspects, namely the substrate material of the strain gauge and the strain alloy material of a sensitive grid of the strain gauge. Whatever strain gauge is selected, the most important point is that the temperature characteristic is self-compensating, so that the temperature drift of the sensor can be ensured to be as small as possible.
In actual work, the sensor usually does not work under a constant temperature condition, so that deformation quantity drifts along with temperature change when the sensor works, the change of the piezoresistance quantity of the weighing sensor is influenced, the voltage change of the weighing analog quantity is caused, and the weighing data is not accurate enough. This variation will affect the accuracy and performance of the sensor and sometimes its unavailability.
Under the condition of no load, except that the resistance value of the strain gauge attached to the elastic body of the sensor changes along with the change of temperature, other physical properties of the elastic body material and the strain alloy also change slightly, the change is the false strain of the strain gauge purely generated by the temperature, and in the case of the sensor, the temperature drift is generated, namely the temperature effect of the sensor.
The temperature effect of the resistance strain gauge is mainly caused by two factors, one is that the resistance of the strain alloy wire (or foil) material changes along with the temperature change, and the other is the additional deformation caused by the change of the linear expansion coefficients of the sensor elastomer and the strain alloy wire (or foil) material, so that the resistance of the strain gauge also changes correspondingly. If the influence of the adhesive is not considered, when the temperature changes by delta t, the change amount of the grid resistance of the strain gauge resistance wire is delta R1, and the corresponding relation is shown.
The temperature self-compensation of the weighing sensor mainly comprises that the resistance strain gauge can achieve self-compensation through resistance obtained by deformation in temperature change. The physical compensation method is to connect a temperature sensitive resistor in series on one arm under the bridge, attach the resistor to the non-deformation area of the elastomer and have a good contact place. The foil grid is cut off by a successive approximation method to reach the required compensation value.
Setting a standard value, setting a weighing value measured at the temperature of 25 ℃ as the standard value, comparing other values to measure the compensation amount, combining different latitudes and variable parameters of the gravity acceleration, calculating through a plurality of times of experiment results to obtain linear compensation data, and performing software compensation.
The sensor is a primary element of the weighing apparatus, is the basis of an electronic weighing system, and directly influences the stability and accuracy of the electronic weighing. Temperature variation is one of the important factors influencing the accuracy of the sensor, and as discussed above, temperature variation directly influences the indexes of the sensor, such as zero point, sensitivity, linearity, repeatability, hysteresis, and the like, none of which are related to temperature, which all indicate that temperature compensation is the most important technical link of the sensor, and temperature drift is an important index for measuring the sensor.
