Application of column weighing sensor in automatic industrial equipment
In modern intelligent manufacturing, automatic batching, warehousing logistics and metallurgical building materials production lines, weight detection is the core link to realize closed-loop automatic control. With the characteristics of high strength, impact resistance, eccentric load resistance and high sealing protection level, column weighing sensor has become the core component of metering module of large-scale automation equipment, which is widely suitable for weighing in batching bin, automatic filling, heavy platform scale, assembly line weight sorting and other working conditions.
This column sensor is made of integrated stainless steel alloy steel elastomer, and the integral cylindrical pressure-bearing structure can bear large-tonnage axial pressure. With the upper and lower flange mounting bases, it can be directly fixed at the bottom of automation equipment rack, bin leg and weighing platform without additional complicated supports. After temperature compensation, the internal high-precision strain gauge can still keep stable output signal in high and low temperature workshop environment; The fully sealed waterproof and dustproof structure meets the IP68 protection standard, which can adapt to the harsh production site with dust, water vapor and slight spraying, and greatly reduce the probability of equipment failure. Automatic equipment weighing system is usually used in parallel with multiple column sensors. When the material or workpiece exerts pressure, the elastic body linearly deforms, and the strain gauge converts the weight into a standard analog signal and transmits it to the weighing instrument or PLC control system. The equipment relies on real-time weight data to complete the automatic process: the filling equipment automatically starts and stops the valve to accurately control the quantity, the batching production line automatically mixes the raw materials according to the warehouse weight, the logistics assembly line completes the sorting and elimination according to the weight, and the heavy storage equipment monitors the material stock in real time, so as to realize the whole automatic operation without intervention.
Compared with cantilever beam and single-point sensor, column weighing sensor have stronger compression resistance and outstanding lateral impact resistance, and have obvious advantages in heavy-duty and frequent vibration automation equipment. Matching flange and spherical bearing head can automatically offset the lateral torsion caused by equipment installation deviation and thermal expansion and contraction, effectively protect the sensor body and prolong its service life. At the same time, the product adapts to the transformation of old automation equipment, replaces the traditional mechanical weighing device, and quickly completes the digital upgrade of the production line. Stable weighing data is the basis for automatic equipment to accurately perform the process. Column weighing sensor gives consideration to high range, high stability and strong environmental adaptability, helps all kinds of automatic equipment to realize high-precision weight detection and closed-loop control, reduces material loss and improves production efficiency, and is an indispensable core sensing accessory for heavy-duty automatic production line.
