Environmental selection of electronic crane scale installation

Before the electronic crane scale is installed, the first choice is to choose the installation location. The choice of the installation location should consider the surrounding environment, which has a great impact on the use and maintenance of the electronic crane scale.

There are mainly the following aspects:

1:Temperature and relative temperature. For analytical balances, the room temperature is required to be between 18 and 26 degrees, and the temperature fluctuation should not exceed 0.5 degrees per hour.

2:Dustproof. Dust has a great influence on the electronic balance. The dust attached to the agate knife and the knife pad will increase the variability of the balance, and it will make the weight inaccurate if attached to the weight. For electronic balances, dust in the weighing pan or large dust in the air also makes the balance unstable.

3:Other environmental conditions. The balance cannot be affected by vibrations, air currents and other strong magnetic fields.

4:The balance room and each electronic balance must have a dedicated person in charge, and have use and repair records to maintain and maintain the balance.

Seven important rules for choosing the location of the electronic crane scale:

1:The installation site should avoid high-voltage transmission lines. Electromagnetic coupling and electrostatic coupling cause the transmission cable to interfere with the signal line of the electronic platform scale. The longer the signal line, the stronger the interference. Covering the signal wire with a well-grounded metal mesh protection tube can theoretically suppress interference and improve weighing accuracy.

2:Do not install near large substations.

3:The installation location of the electronic crane scale should be far away from strong radio frequency interference sources, such as post and telecommunications, television stations, etc.

4:Comprehensively understand the soil pressure resistance, frozen layer and water level of the installation site, confirm that the local installation is suitable, and then determine the specific construction plan.

5:It has an independent power supply to avoid common electricity with frequently started electrical equipment and high-power electrical appliances.

6:The installation location should also consider the wind direction, and try not to install the electronic platform scale on the "air outlet". Otherwise, when the monsoon is blowing, the electronic platform scale will not be able to display a stable and accurate weighing value.

7:There is a relatively spacious installation site, and there is enough space to build up and down straight approach roads. The length of the approach road is approximately equal to the length of the scale body; sharp bends are prohibited for the approach road. The gentle slope is to slow down the impact of the load cell when the car is on the scale.
