Explosion proof electronic truck scale

Explosion proof electronic car scales are manufactured using utility model technology. By installing relevant explosion-proof weighing appliances and explosion-proof weighing modules on the scale platform to form an explosion-proof system, the links that may generate explosion sources (electrical short-circuit sparks, electrostatic friction sparks, high temperature concentration, etc.) in the system are eliminated or cut off, thus achieving the purpose of using the scale in environments with explosion hazards.

　　1、 Product specifications

The electrical part of the explosion-proof electronic car scale has explosion-proof function. The number of scale body sections can be customized according to customer requirements, and the size will be selected according to the length of the vehicle. All sizes can be customized, and large screens, computers, weighing software, etc. can be optionally selected.

　　2、 Composition of the product

Explosion proof truck scale consists of four parts: explosion-proof scale body, explosion-proof junction box, explosion-proof instrument, and explosion-proof sensor. A single platform scale has 4 sensors, a double platform scale has 6 sensors, a 3-section scale has 8 sensors, and a 4-section scale has 10 sensors.

　　3、 How to choose

Depending on your usage environment, sensors and junction boxes are generally intrinsically safe and explosion-proof. The explosion-proof level of sensors and junction boxes should be checked for different gases and areas. If the instrument is arranged on site, the manufacturer generally provides explosion-proof configurations. If used indoors, general instruments can be selected to install safety barriers to isolate hazardous and safe areas. In addition, the limit part of the car scale is generally treated with spark free treatment (the limit impact part is made of copper)

　　4、 Selection and Configuration

1. Intrinsic safety configuration: Place all explosion-proof weighing instruments, explosion-proof sensors, and explosion-proof junction boxes in hazardous areas.

2. Composite configuration: Place non explosion proof weighing instruments in a safe area, place the scale body, explosion-proof sensors, and explosion-proof junction boxes in a hazardous area, and connect them with isolation barriers in the middle.

3. Explosion proof configuration: The instrument itself is not explosion-proof, but is placed in a specially customized explosion-proof box to achieve explosion-proof effect.

　　5、 Advantages of Explosion proof Electronic Truck Scale Technology

1. The safety barrier is built-in, reducing the number of faulty links and making it more reliable;

2. The explosion-proof weighing sensor adopts a bridge type sensor, with stainless steel laser welding sealing and steel ball bearing, which has good automatic centering ability and dynamic response, making the sensor resistant to eccentric load.

3. The explosion-proof weighing display instrument adopts patch component technology internally, with a beautiful appearance and a large function.

4. Explosion proof grade: EX ia Ⅱ CT5, with a wider range of adaptability.

　　6、 Product Features

1. All explosion-proof electrical components adopt intrinsic safety explosion-proof or explosion-proof methods.

2. High precision: meets the standards of Level 3 weighing instruments, reaching over one ten thousandth

3. Long distance transmission: up to 200 meters or more (external devices can reach 1000 meters)

4. Prevent malicious remote control

5. High strength U-shaped steel structure weighing platform, shot blasting anti-corrosion treatment, sturdy and durable

6. Anti RF interference

7. Zero point tracking, self diagnosis, clock, data power-off protection

8. Overload, underload and other status prompts

9. Digital filtering and automatic zero tracking function

10. Zero setting, skinning, skinning, micro printing and other functions

11. Automatic switching of division values: higher display accuracy

12. Self diagnostic function: multiple error message prompts and alarms

　　7、 Installation method

There are two ways to install a weighing scale: with and without a foundation pit. With a foundation pit, the weighing scale is installed in a pit with the surface of the scale level with the ground. Its advantages are easy to use and small footprint, but in case of poor drainage, it is prone to water accumulation and moisture, and installation and maintenance are also inconvenient. No foundation pit refers to the installation of the weighing scale above the ground, with the weighing platform on top of the ground. This installation method is easy to maintain and cost-effective, but protective measures should be taken on both sides of the weighing scale to prevent it from being accidentally hit by vehicles.
