High-precision anti-vibration electronic balance

Abstract

The invention discloses a high-precision anti-vibration electronic balance. The high-precision anti-vibration electronic balance comprises a weighing sensor, a signal amplifier, a signal filter, an A/D (analog/digital) converter, a controller, a display screen, a control mainframe, an audible and visual alarm, a vibration compensation sensor, a temperature compensation sensor and a signal receiver. An output end of the temperature compensation sensor is connected with an input end of the controller, the vibration compensation sensor and the weighing sensor are subjected to actions of mechanical vibration signals simultaneously, and output ends of the vibration compensation sensor and the weighing sensor are simultaneously connected with an input end of the signal receiver. An output end of the signal receiver is connected with an input end of the signal amplifier, an output end of the signal amplifier is connected with an input end of the signal filter, an output end of the signal filter is connected with an input end of the A/D converter, and an output end of the A/D converter is connected with the input end of the controller. The high-precision anti-vibration electronic balance has the advantages that weighting precision is improved while weighting speed is increased, and dynamic stability in operation of weighing systems in severe environment is improved.

Description

technical field [0001] The invention relates to the technical field of electronic balances, in particular to a high-precision and anti-vibration electronic balance. Background technique [0002] People call a balance that uses electromagnetic force to balance the gravity of an object to be called an electronic balance. It is characterized by accurate and reliable weighing, fast and clear display, automatic detection system, simple automatic calibration device and overload protection device. When the existing electronic balance works in a workshop with many large machines, the weighing accuracy of the electronic balance will be affected due to interference from ground vibration. Moreover, the resistance value of the sensitive grid of the sensor in the existing electronic balance will be affected by temperature, and the temperature change will cause the resistance value of the sensitive grid of the sensor to change, which will also cause the weighing accuracy of the electroni...

When the existing electronic balance works in a workshop with many large machines, the weighing accuracy of the electronic balance will be affected due to the interference of the ground vibration.

Moreover, the resistance value of the sensitive grid of the sensor in the existing electronic balance will be affected by temperature, and the temperature change will cause the resistance value of the sensitive grid of the sensor to change, which will also cause the weighing accuracy of the electronic balance to decrease.
