What is the working environment like for electronic vehicle scales? What issues should be noted when using electronic vehicle scales? What are the characteristics of electronic vehicle scales? Here, we will answer all your questions.
**Introduction to Electronic Vehicle Scales:**
The English term for an electronic vehicle scale is "Electronscale." It is primarily used as a weighing device by factories and merchants for bulk goods measurement.
**Characteristics of Electronic Vehicle Scales:**
It fundamentally addresses problems such as corrosion and reduced accuracy that arise from exposure to rain, sunlight, acid-alkali environments, and thermal expansion/contraction experienced by fully steel-structured electronic floor scales. The electronic vehicle scale has strong anti-corrosion capabilities, stable structure, high self-weight, accurate positioning, no deformation, and is easy to maintain. It is suitable for public weigh stations, chemical enterprises, ports, docks, freezing industries, and other sectors with high anti-corrosion requirements.
**Requirements for the Working Environment of Electronic Vehicle Scales:**
1. **Humidity of the working environment:** ≤95%
2. **Power supply:** 220V error range: -15%~+10%, 50Hz maximum error: ±2%
3. **Temperature of the working environment:** Sensors: -20℃～60℃; Weighing instrument: -10℃～40℃
4. **Maximum safe load:** 125% F.S. of the maximum weighing capacity
5. **Temperature difference changes:** ≤5℃/h
6. **For some special environments:** Determined according to needs
**Maintenance of Electronic Vehicle Scales:**
To ensure long-term precise and safe use of electronic vehicle scales, it is necessary to understand how to maintain them and perform regular maintenance.
1. Frequently check if all wiring connections are loose or broken, and ensure the grounding wire is secure.
2. When the weighing instrument is not used for a long time, power it on periodically based on environmental conditions to prevent moisture or other harmful gases from affecting its reliability.
3. Avoid placing the weighing instrument near heat sources or vibration sources.
4. Ensure there are no flammable/explosive gases or dust in the usage environment.
5. Do not connect inductive loads to the same phase line as the weighing instrument.
6. When the weighing instrument is unused for a long time, when replacing fuses, moving positions, or cleaning dust, remember to disconnect the power.
**Usage Precautions for Electronic Vehicle Scales:**
1. During weighing, vehicles must not be parked on the scale for extended periods.
2. Before vehicles go on the scale, wait for the weighing instrument to start up and display zero before following staff instructions to get on the scale.
3. Each time a vehicle is weighed, both getting on and off the scale requires careful driving, with a speed not exceeding 15 km/h.
4. Vehicles going on the scale should drive within the safety yellow lines on both sides of the scale.
5. Keep the pit clean and free of garbage or items.
6. Regularly check the scale platform during use to ensure it remains centered in the pit to avoid edges touching surrounding concrete surfaces, which could affect weighing accuracy.
7. The printer's power cord should be plugged into a well-connected socket to prevent power outages during printing. When replacing print paper, keep your hands clean to avoid oil stains, which can harden the rubber wheels, causing slipping and resulting in unsmooth printing.
8. In rainy weather, ensure proper drainage to avoid sensors being submerged in water, which can reduce sensitivity and shorten their lifespan.
