Industrial electronic scales are indeed affected by temperature. Temperature changes can cause changes in the measurement accuracy of electronic scales. The main impacts include the following aspects:
Mainboard heating: During long-term operation, the motherboard of the electronic scale may cause the temperature to rise due to heat, which in turn affects the measurement accuracy. To solve this problem, a temperature chip can be added to the motherboard, and the chip can react to different temperatures and perform algorithm calculations to reduce the impact of temperature on measurement accuracy.
Sensor sensitivity: The strain gauge in the sensor will change its resistance value and other physical properties as the temperature changes, resulting in false changes in the measurement system and affecting accuracy. In order to compensate for this temperature drift, a symmetrical series compensation resistor can be connected at the input end of the bridge to reduce the bridge voltage and compensate for the output sensitivity.
Ambient temperature: Drastic changes in ambient temperature can cause the measurement error of the electronic scale to increase. For example, in the cold winter, if the electronic scale is used on the ground, antifreeze and preheating work needs to be done to prevent components from freezing and measurement errors.
