What should I pay attention to when using a weighing sensor?

The use of weighing sensors in modern technology and industry is ubiquitous, as resistance strain type weighing sensors themselves are sturdy, durable, and reliable electromechanical products. However, in order to ensure testing accuracy, there are still many issues that need to be paid attention to in use. So, what precautions should be taken when using weighing sensors? The following are some issues that must be noted when using weighing sensors:

Firstly:

Horizontal adjustment: There are two aspects to horizontal adjustment. One is that the installation plane of a single sensor mounting base needs to be adjusted horizontally using a level gauge. On the other hand, it means that the installation surface of multiple sensor mounting bases should be adjusted to the same level as much as possible (using a level gauge), especially in weighing systems with more than three sensors. The main purpose of doing so is to ensure that the load borne by each sensor is basically consistent. The loading direction of each type of weighing sensor is determined, and when we use it, we must load in this direction. Lateral forces, additional bending moments, and torque forces should be avoided as much as possible.

Secondly:

Although the weighing sensor has a certain overload capacity, it should still be prevented from overloading during the installation process of the weighing system. It should be noted that even short-term overloading may cause permanent damage to the sensor. During the installation process, if necessary, a cushion block of the same height as the sensor can be used to replace the sensor first, and finally, the sensor can be replaced. During normal operation, sensors should generally be equipped with mechanical structural components for overload protection. If a screw is used to fix the sensor, a certain tightening torque is required, and the screw should have a certain depth of thread insertion. Generally speaking, fixed screws use high-strength screws.

Next:

Try to use structural accessories with automatic positioning (resetting) function, such as spherical bearings, joint bearings, positioning fasteners, etc. They can prevent certain lateral forces from acting on the sensor. It should be noted that some lateral forces are not caused by mechanical installation, such as lateral forces caused by thermal expansion, lateral forces caused by wind force, and lateral forces caused by vibration of agitators on certain container scales, which are not caused by mechanical installation. Some scales must be connected to accessories on the scale body (such as the feeding pipeline of the container scale), and we should make them as soft as possible in the direction of the sensor loading spindle to prevent them from being damaged; Eat&# quo; The actual load of the sensor causes errors.

Then:

Sensors should use hinged copper wires (with a cross-sectional area of approximately 50mm2) to form electrical bypasses to protect them from hazards caused by welding currents or lightning strikes. During the use of sensors, it is necessary to avoid strong thermal radiation, especially on one side.

Finally:
　 　 　 　 　
Try to set up some around the weighing sensor as much as possible; Baffle”, Even cover the sensor with a thin metal plate. This can prevent debris from contaminating the sensor and certain movable parts, and this; Staining; It often causes discomfort in the movement of the movable part, which affects the weighing accuracy. The following methods can be used to determine whether the system is experiencing discomfort in movement. Add or subtract approximately one thousandth of the rated load on the weighing platform to check if the weighing display shows any response. If there is a response, it indicates that the movable part is not affected; Staining&# quo;.
