The principle of electromechanical surface measurement
What is a level gauge (electromechanical level gauge): The weight of the gauge is placed on the measuring tape through a counter wheel. The tensile force of the weight decreases when it hits the surface of the product. This is recognized, the direction of rotation of the motor is reversed and the bar returns. As the weight of the assay moves downwards, the rotation of the wheel is calculated using the non-contact method. Each counting pulse corresponds to a certain length. The surface is obtained by subtracting this length from the total length (height of the tank)
Continuous surface measurements in bulk solids
Ancient sailors used weights on ropes to test the depth of the sea floor. In industrial level measurement, the basic idea of sound is still used in the electromechanical system. Applications involving bulk solids often use electromechanical surface measurements. Cost-effective devices provide safe measurements in highly dusty environments.
Electromechanical level gauge systems measure the weight of the surface in silos with concentrated, fine or coarse solids in tanks. Due to the minimal fully electronic digital control, there is no reduction in the weight of the sensor in the power outlet and there is no danger to the transmission systems. Often used in applications containing cereals, plastic granules, powders.
Application of electromechanical level gauge
- The result of the measurement under the influence of environmental factors such as sound waves, dust, static electricity, humidity and dielectric, etc. can not be used for applications in mining, cement, petrochemical, power and power plants.
-
Suitable for various types of materials such as powder, pellets, liquid as well as for open tanks or closed tanks without internal pressure.
-
Complete work with material management system software, monitoring and accurate material management inside the tank
-
Safe measurement in very dusty environments
-
High tensile strength system prevents damage due to immersed weight
Advantages of using an electromechanical level gauge:
- Ineffective of intermediate properties
- Ineffective from the value of dc
- Proven and reliable measurements
