When measuring the weight of some items, some weighing instruments are often used. The existence of these instruments and instruments plays a very important role in the development of the measuring tool industry. Among these measuring instruments, there is a product called weightless scale instrument. With very good performance, it has become more and more applications in recent years. So do you know the advantages of the weightless scale instrument and how to operate it?

There are impurities between the adjustment blocks or joints between the main moving parts and the fixed parts of the weightless scale instrument controller in the weightless scale instrument, the blade or adjustment block falls off, the weight is corroded, and the weight sensor is moved due to abnormal vibration or misoperation. caused by the position.

When the weight loss scale instrument is unloading, when the weight of the material in the bucket reaches the preset value, the loss-in-weight scale instrument controller will output a signal to control the feeder to stop feeding.

●The action time of the relevant relays in the control loop of the loss-in-weight scale instrument controller, the time from opening to closing of the feeding valve, and the lag of the space drop between the feeding device and the bucket will cause packaging weight errors, which are dynamic errors. .

●For some products that are easy to absorb moisture, if they are placed in a humid environment for a long time, a layer of material will adhere to the walls of the bucket and discharge chute, and the residual material will also cause weight errors.

●Clean the weightless scale regularly to ensure the weighing accuracy.

●The weightless scale needs to be grounded reliably to prevent static electricity from affecting the weighing data.

●Regularly refuel the gearbox of the weightless scale to ensure the lubricity of the gear rotation and reduce wear.

● Adopt necessary common mode or differential mode suppression circuit, and also take certain filtering and anti-electromagnetic shielding measures to reduce the entry of interference.

● Take various isolation measures as far as possible to block the spread of interference.

● Try to thicken the width of the power line and reduce the loop resistance, which will help to enhance the anti-interference ability.

●In the design of weightless scale instrument, grounding is an important method to control interference.

●Configure appropriate decoupling capacitors for each key part of the weightless scale instrument.
