The concrete mixing plant is the most common equipment in construction. Load cells are often found in these plants.
The weighing system in a concrete mixing plant includes:
-
Weighing hoppers
-
Load cells
-
Booms
-
Bolts
-
Pins
Among these components, the load cell plays an important role in weighing.
Concrete mixing plants use load cells that face tough conditions. These cells are different from regular electronic scales. They handle factors like temperature, humidity, dust, impact, and vibration. The environment plays a big role in their performance, too. So, it’s crucial for the load cell to stay accurate and stable in tough environments.
In this case, we should consider the following issues when using the sensor.
1. Rated load of load cell = weight of hopper = rated weight (0.6-0.7) * number of sensors
2. Selection of load cell accuracy
A load cell in a concrete mixing plant turns weight signals into electrical signals. The load cell is sensitive to its surroundings. So, handle it with care during installation, use, repair, and maintenance. These factors affect the accuracy of the subsequent weighing.
3. Load considerations
Damage to load cells due to overloads occurs from time to time. Overload protection affects the reliability of the weighing system. You need to consider two parameters: the allowable overload and the ultimate overload.
4. Protection class of load cell
The protection class is usually indicated by IP.
IP: the protection class of enclosures for electrical products with a voltage up to 72.5KV.
IP67: dust-proof and protected against temporary immersion
IP68: dust-proof and protected against continuous immersion
The protections listed do not cover outside factors. This includes damage to small motors or corrosion. The concrete mixing plant is the most common equipment in construction. Load cells are also common in these plants. A concrete mixing plant’s weighing system has a few key parts: the weighing hopper, load cell, boom, bolts, and pins. Among these components, the load cell plays an important role in weighing.
Concrete mixing plants use load cells that operate in tough conditions. Unlike typical electronic scales, these load cells face challenges from the environment. Factors like temperature, humidity, dust, impact, and vibration can all affect their performance. It’s crucial for the load cell to maintain accuracy and stability in tough environments.
