The most common equipment in construction is the concrete mixing plant. Load cells have extensive applications in these plants. A concrete mixing plant’s weighing system has a weighing hopper, load cells, a boom, bolts, and pins. Among these components, the load cells play an important role in weighing.
Unlike common electronic scales, concrete mixing plants weigh in harsh conditions. The environment, temperature, humidity, dust, impact, and vibration affect their sensors. So, it’s vital to ensure the weighing sensors are accurate in harsh environments. They must also be stable.
Application of weighing sensors in concrete mixing plants
In this case, we should consider the following issues when using sensors.
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 converts weight signals into an electrical signal. The sensor is very sensitive to the environment. You must install, use, repair, and maintain it with care. These factors affect the accuracy of the subsequent weighing.
3. Consideration of the load
Overloads damage weighing sensors. Therefore, the presence or absence of overload protection has a certain impact on the reliability of the weighing system. You need to consider two parameters: allowable overload and ultimate overload.
4. Protection class of weighing sensor
The protection class is usually expressed in IP.
IP: enclosure protection class for electrical products with a voltage not exceeding 72.5KV.
IP67: dust-proof and protected against the effects of temporary immersion
IP68: dust-tight and protected against continuous immersion
The above protection does not cover external factors. This includes damage to small motors and corrosion. The most common equipment in construction is the concrete mixing plant.
