Car weighing instrument, also known as portable automotive wheel axis weighing, which is mainly used in the field of automobile manufacturing and automotive detection, by allowing automobiles to dynamically pass or stationary on a certain width of a wide range, each wheel is called each wheel.  Weight, then add the axial weight of the car and the intensity of the car, which in turn determines the function of the stability of the car design according to a certain standard.  It is one of the commonly used verification standard tools commonly used in the field of automobile manufacturing and automotive testing!

STW-18 car weighing instrument structure accessories is usually divided into four parts, namely weighing, wired instruments, data cables, and standard accessories.  Among them, the weighing is typically called four wheels corresponding to the car; the wired instrument is generally 1; the data line is generally 4, connected to the four major models; standard accessories generally include bridge, charger, printing paper,  Ribbon, etc.

The most important structure is called the rendering and its sensors, and its working principle is worth exploring!

The working principle of the model of the car weighing instrument is as follows: When the car tire is applied to the weighing station, the weighing sensor releases the voltage signal, and the output signal size is proportional to the weight of the tire, and the signal is transmitted to  After the amplifier is enlarged, the modulus converter is converted to the digital signal to display in the display.  The single board is the wheel weight value of the car, and the two plates are shafts. According to the axle type, the total weight of the car can be added.

The working principle of the weighing sensor of the automobile weighing instrument is as follows: When the rendering of the pressure-generated deformation, the resistance value of the resistance strainer in the sensor will change the output of the signal.

There are two sensors employed by the rendering sensor, which are embedded structural sensors and integrated structural sensors. At present, the market is more popular with embedded structural sensors.  The embedded structural sensor has more pressure and accuracy than the previous integrated sensor.

The working principle and function of the instrument is mainly to receive sensor signals, and perform calculation and analysis signals, convert to an intuitive value display!

After the above introduction, we learned that the car weighing instrument is really an indispensable tool for automobile manufacturing and testing persons, but is it suitable for any scenario?

Not like this, the use of car weighing instruments is actually a matter of nothing to pay attention to:

1. Sensor and car weighing instruments must be reliably connected, away from strong electric fields, strong magnetic fields, sensors, and automotive weighters should be away from strong corrosive objects, away from flammable and explosive items.

2. Do not use in applications with flammable gas or flammable steam.

3. In areas where the lightning is frequent, a reliable arrester must be installed to ensure personal safety, prevent lightning strikes from damaging the car weighing instrument and corresponding equipment.

4. Sensors and car weighing instruments are electrostatic sensitive equipment, and anti-static measures must be effectively taken in use. It is strictly forbidden to carry out electric welding operations or other strong electric field operations on the weighing stage; in the thunderstorm season, reliable lightning measures must be implemented to prevent  Damage caused by lightning strikes, the damage of the vehicle weighing instrument, ensuring the personal safety and weighing equipment of the operator and the safe operation of related equipment.

5. Before swapping the car weighing and external equipment coupling line, you must first cut off the car weighing instrument and corresponding equipment power supply!  Before plugging the sensor coupling line, you must first cut off the car weighing instrument power supply (shutdown)!  Before plugging the communication coupling line, you must first cut off the car weighing instrument and the upper power supply!

The above is some precautions for the car weighing instrument. In the process of use, the operation process should be specified, eliminating from the source, so as not to occur, there is unnecessary losses!

I believe that as long as we use car weighing instruments in strict accordance with the operation, it will become a good helper, good tools we are in verification work!
