Summer is a hot and rainy season. The electronic truck scale is usually installed outdoors and used in the open air. The equipped electronic components such as the load cell and junction box are affected by damp, lightning and other environments, which are very likely to cause measurement errors. Correct use and maintenance can improve the measurement accuracy of the electronic truck scale in hot and rainy seasons. The following is a brief discussion on some precautions for the use of the electronic truck scale in the hot, rainy and thunder weather in summer.

First, do a good job of waterproofing in summer

1. Waterproof work shall be done in summer. Desiccant shall be placed in the junction box of truck scale without foundation pit. The foundation pit of truck scale in shallow foundation pit shall ensure that the sewer and drainage pipeline are unblocked. The foundation of shallow foundation pit and drainage pipeline shall be unblocked. Frequent inspection and dredging of drainage pipeline shall be carried out to ensure that there is no ponding in heavy rain, and rainwater is not allowed to drain and irrigate the foundation pit. Electronic weighbridge manufacturer In particular, the truck scale in food processing or grain industry should do a good job of rat prevention. When the cable is broken, the joint should be waterproof, and the cable should be sleeved with a metal hose.

2. The scale platform and its surroundings shall be kept clean and dry to prevent water accumulation and other debris pollution, especially the junction box shall be dry and clean, and the desiccant in the box shall be replaced regularly. For extension Electronic loadometer Long service life, take necessary anti-corrosion measures for the weight sensor.

Electronic truck scale

Second, how to use electronic truck scale more safely in thunderstorm weather in summer, and countermeasures

1. When thunder strikes, the power supply of the instrument must be cut off. In case of thunderstorm weather or imminent thunderstorm, the truck scale shall be stopped as soon as possible, and all configuration parts shall be turned off to cut off the power supply.

2. Improve the safety of equipment. In summer, when thunderstorms are frequent, the electronic truck scale installed in the open air is vulnerable to direct lightning damage, Electronic loadometer long Most of the weighing instruments installed indoors are damaged by inductive lightning. When lightning strikes the scale body directly, the components in the weighing sensor and junction box are destroyed. Inductive lightning invades the weighing room through wires, power lines and signals, causing damage to the weighing instruments. In thunderstorm weather, unplugging the power plug of the electronic truck scale can be regarded as an emergency measure, but it will affect the normal work and operation, which is very inconvenient. Effective lightning protection measures can greatly improve the work efficiency. Lightning rod, lightning arrester and other lightning protection devices can be directly installed near the scale body;

3. For the weighing body of electronic truck scale, each weighing sensor is required to be grounded (one end of the grounding wire is connected to the weighing body near the weighing sensor, and the other end is connected to the lower grounding pile of the weighing sensor). For the junction box installed in the foundation, its grounding wire must also be effectively connected to the weighing body. The grounding wire of the whole weighing body is connected to the grounding pile near the weighing body to form a grounding grid. For the weighing instrument installed indoors, the power line and signal line introduced into the weighing room shall be protected by shielding layer, and the shielding layer shall also be effectively grounded, Features of electronic weighbridge The power circuit in the weighing room shall be equipped with power surge protector, air switch and other protective measures. The grounding wire of the weighing instrument shall be connected with the grounding pile of the weighing room to achieve the dual function of anti-interference and lightning protection.

4. After the completion of lightning protection measures, it is necessary to regularly check whether the connection points of all lines in the scale body and the weighing room are in good contact, so as to prevent oxidation, looseness, corrosion and other conditions of the connection points after a long time, so as to prevent them from happening.
