What are the mechanical protection measures for load cell?

The mechanical protection measures of load cell are designed to prevent damage caused by external factors such as impact, vibration and overload. The following are some common mechanical protection measures

A. overload protection device:

1. Limit switch: A physical limit switch is set around the sensor, which can stop the loading process and avoid overload when it reaches the preset position.

2. Safety pin: A replaceable safety pin is installed in the system. When it is overloaded, the safety pin breaks to protect the sensor from damage.

3. Spring buffer: Use the spring as a buffer element to absorb and disperse sudden impact.

B. Vibration reduction measures:

1. Rubber or elastomer damping pad: rubber pads or other elastic materials are placed between the sensor and the supporting structure to reduce vibration transmission.

2. Air spring: uses the compressibility of gas to absorb vibration, which is suitable for high-frequency vibration environment.

3. Hydraulic damper: It consumes energy through the flow of liquid, thus reducing vibration and impact.

C. structural design optimization:

1. Increase the structural rigidity: by strengthening the rigidity of the sensor and its installation structure, improve its ability to resist deformation.

2. Reasonable layout: Ensure that the installation position and direction of the sensor can minimize the influence of external interference.

D. protective device or casing:

1. dustproof and waterproof: use a well-sealed protective cover or shell to prevent dust and moisture from entering the sensor and affecting its performance.

2. Anti-collision protection: add anti-collision materials or designs on the shell to reduce the damage caused by accidental collision.

E.  installation and use specifications:

1. Correct installation: install according to the manufacturer's guide to ensure that the sensor is in the correct state and avoid problems caused by improper installation. Regular inspection: check the state of the sensor and its accessories regularly, find and solve problems in time, and prolong the service life.

F. signal processing and software protection:

1. Overload alarm: overload detection function is set in the control system, and when abnormal load is detected, it will automatically give an alarm or take protective measures.

2. Data filtering: noise and short-term spikes are filtered by software algorithm to improve the accuracy of measurement.

Through the above measures, the load cell can be effectively protected from various unfavorable factors and its long-term stable operation can be ensured. In practical application, you should choose appropriate protection measures according to the specific working environment and conditions.
